RCD’s Series MC resistors utilize precision thick film technology
offering inherently low inductance, exceptional reliability and superior
performance. Heavy plating with NO LEACHTM nickel barrier assures
superb solderability and long shelf life. State-of-the-art production line
enables the industry’s most precise accuracies (0.25% & 50ppm!)
thereby replacing more costly thin-film chips in many applications.
RCD offers low cost offshore assembly of SM and leaded PCB’s (refer
to RCD’s Assembly Services p.114 for more information).

看门狗,又叫 watchdog timer,是一个定时器电路,一般有一个输入,叫喂狗(kicking the dog or service the dog),一个输出到MCU的RST端,MCU正常工作的时候,每隔一段时间输出一个信号到喂狗端,给 WDT 清零,如果超过规定的时间不喂狗,(一般在程序跑飞时),WDT 定时超过,就会给出一个复位信号到MCU,使MCU复位. 防止MCU死机. 看门狗的...[详细]
