[Surprise at the end of the article] Selection of capacitors, antennas, and connectors: we have helped you dig out three treasure resources, come and watch!
If you think of a circuit board as a stage, the electronic components on it are working together to perform a big show. Among them, IC is always the undisputed "protagonist" because it defines the function of the entire circuit and product performance, but this does not mean that the peripheral components as "supporting roles" are dispensable; on the contrary, they are It plays an important role in supporting the performance of core ICs, ensuring the reliability and safety of circuits, and improving system performance.
However, due to the wide variety of these peripheral components and the complexity of the materials, they are destined to require a lot of effort when selecting them. If the selection process is regarded as casting for a big drama, the energy spent on these "supporting actors" is no less than that of IC as the protagonist. For engineers, facing thousands of models of products every day and looking at their glossy "datasheets", it is inevitable that they will be dazzled. The feeling of "finding a needle in a haystack" is not wonderful. If you look at too much, you may even get confused. "Aesthetic fatigue" makes it even more difficult to start.
I understand the difficulties faced by electronic engineers, and this article is specifically here to help you solve your problems!
We have done a round of "audition" for you, and from KYOCERA AVX 's rich product portfolio, we have discovered three categories of components with excellent performance and significant differentiation advantages: capacitors, antennas, and connectors. We recommend them to you so that everyone can Component selection is easier, faster and more accurate.
Okay, no more gossip. What are the outstanding “beautiful points” of these products? Let’s take a look at them one by one.
TCJ capacitors with conductive polymer electrodes
The first one to appear on our recommendation list is the KYOCERA AVX TCJ tantalum capacitor with conductive polymer electrode.
Tantalum capacitors and the most common aluminum capacitors are both electrolytic capacitors. They obtain a stable oxide film dielectric through electroformation to achieve capacitive characteristics. Since the Ta 2 O 5 dielectric film in tantalum capacitors has stronger electrical stability than the Al 2 O 3 dielectric film in aluminum electrolytic capacitors , the capacitance of tantalum capacitors will not change significantly over time, and the capacitance of tantalum capacitors will not change significantly over time. That is to say, there is no obvious aging, so it usually has a longer service life.
Moreover, tantalum capacitors use a special manufacturing process: pressed tantalum powder is sintered into porous tantalum blocks, and then the surface of the porous tantalum blocks is oxidized to obtain a dense tantalum oxide film. This "porous" structure allows tantalum capacitors to obtain a very large surface area in a limited volume. In addition, the dielectric constant of Ta 2 O 5 is higher than that of Al 2 O 3. Therefore, in the same volume, tantalum capacitors have a very large surface area. Capacitors can obtain larger capacitance values.
In addition, in addition to high capacitance per unit volume, stable performance, and long life, tantalum capacitors also have good temperature characteristics and low ESL, so they are ideal for power supply filtering and energy storage applications with high capacitance, high reliability, and high temperature resistance. Ideal.
However, traditional solid tantalum capacitors have a "hot temper" that is very confusing. Because it uses MnO 2 as the cathode electrolyte, its ability to withstand surge voltages and surge currents is poor. When encountering voltage spikes, the tantalum anode may come into contact with the MnO 2 cathode, causing a chemical reaction, causing short circuit failure, and even triggering Smoke and flames have become a major safety hazard in electrical circuits. In order to solve this problem, people are exploring the use of new materials to replace the "bad temper" MnO 2 as the cathode material of tantalum capacitors. Therefore, polymer tantalum capacitors using the polymer material PEDT came into being.
KYOCERA AVX's TCJ capacitors are an outstanding product series among polymer chip tantalum capacitors. They do not cause fires and secondary breakdown effects, and have lower ESR. They are iconic polymer tantalum capacitor products. . At the same time, the TCJ series tantalum capacitors are compatible with three 260°C reflow soldering processes and have passed the surge current test. The CV range is 0.47μF to 470μF / 2.5V to 125V. 16 package sizes are available, and they are compliant with the RoHS directive and are suitable for It has a wide range and can meet the design requirements of many applications such as smartphones, tablets, laptops, LCD TVs, power supplies, etc. It is a choice worthy of attention when selecting polymer tantalum capacitors.

Ethertronics/KYOCERA AVX Standalone Antenna
After entering the era of the Internet of Things, the widespread application of wireless technology has brought a variety of new applications to a variety of possibilities. With the explosive growth of wireless connection applications, the demand for various types of antennas is also becoming increasingly strong.
If in the field of polymer tantalum capacitors, KYOCERA AVX products attract attention with their excellent performance, then in the field of antennas, the biggest "beautiful point" of KYOCERA AVX products is just one word - complete.
As we all know, when selecting an antenna, you need to consider many factors from different dimensions, such as:
Experience tells us that based on the above selection factors and through layers of screening, we can find a suitable antenna product. However, if the supplier's product portfolio is not rich enough, we are sometimes disappointed to find that after careful screening, we cannot find the antenna product or solution we want.
However, this disappointing situation will basically not occur in KYOCERA AVX. This is because KYOCERA AVX has a comprehensive product layout for different wireless technologies and application scenarios, among which "there is always one that suits you." Even if standard products cannot meet the application needs, KYOCERA AVX's customized solutions can achieve customer satisfaction! This is also the key reason why we recommend the KYOCERA AVX antenna product line to everyone.

KYOCERA AVX Connector Solutions
Through the above introduction of KYOCERA AVX polymer tantalum capacitors and antenna products, you may have felt their characteristics in pursuing higher performance and providing a more comprehensive product portfolio. In fact, these features have become the technical DNA of KYOCERA AVX and are also reflected in other product lines.
For example, in the connector solutions we recommend below, KYOCERA AVX can provide "performance-driven" solutions for a wide range of markets such as industrial, consumer, medical, energy, transportation, telecommunications and automobiles, covering wire-to-wire , wire-to-board, board-to-board, RF, FPC and other product types.
If we go deeper into the interior of these connector products, we will find another commendable "beautiful point" of KYOCERA AVX interconnection solutions, which is: in-depth optimization based on the requirements of specific applications to form differentiated advantages The product.
Let's give an example. The secret to the high performance of KYOCERA AVX connector products is largely due to its excellent contact technology. In particular, its innovative integrated interconnection solution, compared with hard-wired connections and "plug + socket" two-piece solutions, only requires a connector joint to be directly mated with a wire, making it simpler and more efficient. Faster and more reliable electrical connections. Around this interconnection architecture, KYOCERA AVX has launched Poke Home connector products that are cost-effective and easy to operate, as well as IDC that performs better in terms of reliability and is more efficient and cost-effective in large-scale cabling and termination. connector (insulation displacement connector), which has gained wide market recognition.
At the same time, in order to meet the more "harsh" requirements of specific applications such as LED lighting in terms of size reduction and cost reduction, KYOCERA AVX has specially launched the STRIPT™ "shell-less" connector, which only retains "exposed" contacts. While the shell of the traditional connector is removed, it can still provide complete electrical connection functions and meet reliability requirements. It has outstanding competitive advantages in achieving design miniaturization, cost control, and improved heat dissipation performance.
If you dig carefully, similar examples are not uncommon in KYOCERA AVX connector products, which means that choosing these connectors will bring you additional value and surprises beyond the technical specifications marked in the Datasheet.
