4000V MOV Protection Device , 230pF Sensitive Components Chip Varistor

Sensitive Components Chip Varistor 10D511K 510V For Surge Overvoltage Protection

Introduction Of The Chip Varistor 10D511K

MLA (Multilayer Varistor), SMD transient voltage suppressor, also known as zinc oxide varistor or "surge absorbers", is a kind of voltage and current-voltage properties of symmetric properties resistors. MLA is semiconducting ceramics (zinc oxide) for materials through lamination technology (multi-layer) manufacturing, with excellent instantaneous energy absorption capacity, as well as fast internal thermal fugitive character, to achieve the effect of protection circuit, also known as multilayer varistor.

Dimension Of The Chip Varistor 10D511K

Highly Recommended:
1. In the drawing board, it is recommended that the A solder joint be used as the L line, the B solder joint
as the N line, and the copper skin connected to the B solder joint is routed around the pressure-sensitive
chip circle (the entire diameter D should be regarded as belonging to the A solder joint.

2. For the sake of safety arcing, the circular edge of the chip should be at least 2.5mm away from any

other conductive device, as shown in the figure above (in order to prevent mutual displacement with

other devices during patching, if the space allows, please reserve the larger the interval is. Okay.)
3. The use of varistors in DC circuits has unfavorable factors. It is not recommended to use varistors in
rectified DC circuits. Please consider carefully or contact our company at 18128566098

Specification Of The Chip Varistor 10D511K

For different voltage application environments, we recommend the following pressure sensitive
combinations to provide overvoltage, surge and lightning stroke protection for ACLED.

Because the varistor is easy to deteriorate in an environment with large voltage fluctuations, the varistor
voltage should be selected as much as possible under the premise that the IC (MOS tube) + lamp bead
on the lamp board has a sufficient withstand voltage and the voltage fluctuation area is large. A
combination with a higher value should be selected, and a varistor with a large flow and a large size
should be selected as far as possible under the premise of the cost.
