High Surge Type Multilayer Chip Varistor 2220 5650 5750 85V 4500A for Surge Current Suppression of Communication Equipment
Description
Zinc oxide varistor is the 1 kind of zinc oxide as the main body, adding a variety of metal oxides as additives, after high temperature sintering in the air made of polycrystalline semiconductor ceramic elements. Varistor is the 1 type of voltage limiting protection device. The varistor and the protected circuit element are connected in parallel in the circuit. When lightning overvoltage, electrostatic overvoltage or transient operating overvoltage occur in the circuit, the varistor will quickly drop the voltage at both ends to a relatively fixed safe voltage value with a response speed of nanosecond time by using the nonlinear characteristics of the varistor, thus avoiding the damage of the protected circuit element due to the impact of overvoltage.
Features
1) SMD small patch, saving space and convenient production;
2) The response time is ns level, and the response speed meets various circuit protection requirements;
3) High surge suppression, the same volume surge capacity is much greater than TVS;
4) Stable high temperature performance, no derating at 125 ℃;
5) Low leakage current IL<10μA;
6) Bidirectional non-polar protection, low clamping voltage;
7) Better than UL94V-0 flammability rating;
8) comply with RoHS environmental standards
Application
1) Automotive electronic applications: car control unit, electro-hydraulic brake, ABS/ESP, sunroof, window control and other load sudden drop protection and quick start protection;
2) Industrial instrumentation, control and measurement equipment, security cameras, electronic watt-hour meter control board;
3) 5G communication base station, Netcom equipment, network product interface, leakage protector control board;
4) ESD protection of video and audio line I / O port, high-speed data line (such as HDMI, USB 3.0, IEEE 1394 interface, RF antenna, RF module);
5) IEC 61000-4-5 surge protection, IEC 61000-4-4 EFT protection, ESD protection in accordance with IEC 61000-4-2 (level 4)
