Multilayer Chip Varistor for Surge Current Suppression – SDVL Series
Overview
Based on multilayer construction and improved material with excellent energy volume distribution and power dissipation, SDVL series varistors provide the features of high energy absorbing ability and fast response, and are especially designed to suppress high energy transient voltage of circuit.
 
SDVL series cover wide DC operating voltage range from 5.5V to 100V with the size including 3216, 3225, 4532 and 5650.
Background
With the increasing tendency of slim and flat of electronic devices, big and lead type components in power circuits are requested to be replaced by SMD type, such as varistor, NTC thermistor, coil, and so on.
 
Thanks to profound experience in varistor technology, Sunlord developed multilayer chip varistor successfully to suppress large surge current to meet the market’s requirements. They are suitable for numerous applications on power supply, i.e., automotive application, LED lighting, smart grid, and so on.
