Could you give me some information about classic circuits and microcontrollers for beginners? Thank you! I just graduated. I was really touched after reading what you said. I must learn from you and take you as an example. I hope seniors can help me find some information. Mainly some information about circuits and microcontrollers. Thank you!!!
Our company is the agent of Korean electronics KEC (KEC first-level agent, with agent certificate), can deliver directly in Hong Kong and mainland China, and can open 17%. We are the agent of KEC's full range of products. Including: various types of diodes, triodes, 78 voltage regulator series IC (such as: KIA7805, KIA7812), 79 series voltage regulator IC (such as: KIA7905, KIA7912), operational amplifier IC (such as: KIA4558, LM358 (KIA358), LM393 (KIA393), LM324 (KIA324), LM494 (KIA494), LM339 (KIA339) etc.). Reset IC (KIA7019/KIA7029, KIA7039, KIA7045), etc., high-precision reset IC (KIA7419/KIA7432/KIA745), etc., as well as KEC's MOS tubes, KEC series amplifier tubes. In terms of products, KEC Semiconductor can replace the relevant models of international brands such as Sanyo, Philips, Toshiba, ROHM, NEC, Samsung, Fairchild, TI, etc. The price is lower than the above brands, and the delivery time can be shortened by at least half. In terms of tubes, they can directly replace Toshiba amplifier tubes (such as KEC brand KTB817, KTD1047 can directly replace Toshiba's A1941 and C5198 tubes). Our company's supply channels are unique and stable, and we have received strong support from KEC's original factory. We can provide KEC's original technical support, stable prices, and long-term stable supply (we can sign a supply guarantee agreement with customers). Amplifier tube models: 778/998 power 60W, 688/718 power 80W; 817/1047 power 100W, TIP35C/TIP36C power 125W. Power series components: For MOS, we can directly replace the following MOS models of IRF and Fairchild: IRF840/830/740/730/640/630, Fairchild 50N06/20N50/1N60/2N60/4N60/7N60/22N60/4N65/7N65/3N70/4N80/9N90/7N80/1N80. We also have a large number of stock: KID65003AP, KID65083AP, KIA431/KIA431F, 2N3904/3904S, KTA1023/KTD1027, KTB1366/KTD2058, KTB631/KTD600K, KTA1273, KDV804S, and other components. For strong companies, we can provide monthly settlement. If you need any help, please contact us. Contact information: 13928487140 Mr. Gou. QQ: 372427836.
