1. Functional characteristics: Varistors can quickly conduct during voltage surges, absorb overvoltage energy, protect circuits from surge damage, and are suitable for lightning protection and overvoltage protection of power supplies, household appliances, and other equipment.
2. Parameter selection: The appropriate varistor voltage value should be selected based on the working voltage, and the surge current tolerance should be matched with the equipment requirements to ensure that it is in a high impedance state during normal operation.
3. Installation points: It is recommended to connect it in parallel with the protected circuit, with short and secure leads, avoiding high temperature environments, staying away from flammable components, and improving stability.
4. Applicable scenarios: Widely used in electronic products, industrial equipment, smart homes, etc., effectively responding to voltage surges caused by lightning strikes, power fluctuations, etc.
5. Safety reminder: Although it is a protective component, it is still necessary to cooperate with other protective measures, regularly check the status, and ensure that the protective performance is long-lasting and reliable.
