Multilayer Chip Metal Oxide Varistor 0806 1206 1210 1812 For LED Power Circuit
Description Of The Multilayer Chip Metal Oxide Varistor
Multilayer chip varistor is a SMD packaged varistor. It is made of multilayer monolithic structure and semiconductor ceramic technology. It has small parasitic inductance, small size, high SMT efficiency, short response time, high operating temperature, and protection The advantage of strong ability. It is applied to the power protection of LED high-voltage linear drive schemes, and suppresses transient overcurrent caused by grid surge, short circuit or overload in LED lighting, as well as transient overvoltage caused by grid voltage fluctuations and inductive load switching, including IEC61000 -4-2, IEC61000-4-5 and other transient events used in electromagnetic compatibility (EMC) standards.
At present, the LED industry has begun to adopt optoelectronic integrated high-voltage linear solutions for various smaller filament lamps, bulb lamps, flat lamps, etc. The electronic components and lamp beads are integrated on the aluminum substrate at the same time, which means that all components must be patched. Therefore, the varistor as a protection device must also adopt SMD components. The original mass-produced laminated chip varistor suitable for LED lighting AC power protection, from 0604 to 1812, has the characteristics of thin thickness, small volume, and large flow rate. It can replace the plug-in varistor. , With fuse, resistor, bridge stack, it can meet the combined wave test above 1KV, which is enough to meet the needs of LED protection.
Features Of The Multilayer Chip Metal Oxide Varistor
* SMD type suitable for high density mounting
* Excellent clamping ratio and strong capability of voltage surge suppression
* High voltage varistor, suitable for AC circuit
* SMD small patch, save space and facilitate production;
* High surge suppression, the surge capacity of the same volume is much greater than TVS;
* Stable high temperature performance, no derating at 125°C;
* Low leakage current IL<5μa;
* Two-way non-polarity, low limit voltage;
* Better than UL94V-0 flammability rating;
* Comply with RoHS environmental protection standards
Applications Of The Multilayer Chip Metal Oxide Varistor
* Used for Power supply, Network Interface, LED lighting.
* Able to replace part of leaded Varistor.
