82537040 Description

Short technical summary and product information.

The Würth Elektronik 82537040 is a surface-mount multilayer chip varistor (MLCV) in the 0402 (1005 metric) package, part of the WE-VS series. It provides overvoltage protection for low-voltage electronic circuits.

 

Key electrical specifications include a varistor voltage of 8V (tested at 1 mA), maximum AC operating voltage of 4V, and maximum DC operating voltage of 5.5V. The device can handle peak pulse currents up to 20A (8/20 µs waveform) and absorb up to 0.04J of energy (10/1000 µs waveform). Clamping voltage is 21V maximum at 1A.

 

The varistor is designed for operating temperatures from -40°C to +85°C and has a typical capacitance of 220 pF at 1 MHz. It is RoHS, REACH, and halogen-free compliant, with MSL Level 1 moisture sensitivity.
