Multilayer Ceramic Chip Capacitors

Multilayer Surface Mount Ceramic Capacitors are constructed by screen printing alternative layers of internal metallic

electrodes onto ceramic dielectric materials and firing into a concrete monolithic body, then completed by application of

metal end terminations which are fired to assure permanent bonding with the individual internal electrodes.

Multilayer ceramic capacitors have various features such as large capacitance values in small sizes and excellent high

frequency characteristics.

Moreover, chip capacitors can be used on surface mount assembly equipment. Our fully integrated manufacturing and

total quality control systems ensure unprecedented high standards of quality and reliability.

Chip Capacitor Selection

Selection of the most suitable capacitor for any application is based on the following:

Dielectric Type

The choice of dielectric is largely determined by the temperature stability required.

COG (NPO)

Capacitance change with temperature is 0-30ppm/°C which is less than -0.3%°C from -55°C to +125°C. Typical capacitance

change with life is less than -0.1% for NPOs, one-fifth that shown by most other dielectrics. NPO formulations show no aging

characteristics.

X7R

Its temperature variation of capacitance is within ±15% from -55°C to +125°C. This capacitance change in non-linear.

Z5U

Despite their capacitance instability, Z5U formulations are very popular because of their small size, low ESL, low ESR and

excellent frequency response. These features are particularly important for decoupling application where only a minimum

capacitance value is required.

Y5V

Y5V formulations are for general purpose use in a limited temperature range. They have a wide temperature characteristic

of +22% - 82% capacitance change over the operating temperature range of -30°C to +85°C. Y5Vs high dielectric constant

allows the manufacture of very high capacitance value (up to 22MF) in small physical sizes.

Capacitance Value & Tolerance

Determined by circuit requirements. Note that chip prices decrease with lower capacitance value and looser tolerance.

Voltage

Determined by circuit requirements. Units are designed to exceed the withstanding voltage specification, i.e., the user need

not incorporate an additional safety margin.

Capacitor Size

Select the smallest unit permitted by the circuit constraints that provides the required capacitance and voltage rating.

Smaller units are generally less expensive : 0805 is the most economical size.

Capacitor Termination

Termination choice is largely determined by the chip attachment method. Silver-palladium is adequate for most applications

involving soldering or solder reflow.

Nickel barrier is standard and recommended for units exposed to repeated solder cycles, to minimize leaching of the

termination.
