* Question
| Varistor specifications |
* Answer
| For the selection of varistor, which indicators must be considered? For signal transmission lines, ESD protection must be considered:
(1) The maximum working voltage of the varistor is greater than the operating voltage of the circuit; (2) The varistor capacitance andThe signal transmission rate is matched, that is, when the varistor is transmitting signals,For the power supply line, inductive overvoltage and operation overvoltage protection, we must consider: (1) The maximum working voltage of the varistor is greater than the working voltage of the circuit; (2) The maximum peak current and energy tolerance of the varistor must be greater than that in the circuit.Induced overvoltage, operating overvoltage amplitude. |
