FAQ

Q: What parameters need to be considered in resistor selection?

A: 1. Rated power
Power = current square x resistance, a small resistance, if the heat cannot be dissipated in time, it will overheat and burn out. So be careful not to let the power exceed the standard when designing the hardware

2. Working temperature and high temperature power limitation
Operating Temperature Range -55℃to +155℃,but in actual use, there is a power limit at high temperatures.

3. The maximum working voltage of the varistor
Maximum Working Voltage, Maximum Overload Voltage, the two parameters are for the instantaneous peak voltage. In normal design, it is ok to control the voltage not to exceed the standard according to the actual working power. If the circuit has glitches, you need to consider whether the peak value exceeds the standard.
