Surface Mount Varistors
VA Series Automotive Grade 125°C
Overview
Applications
KEMET's VA series of varistors are transient suppressors
with temperature independent suppression characteristics
enablingꢀprotectionꢀfromꢀ−55°Cꢀtoꢀ+125°C.
Typical applications include almost all-electronic systems
in an automobile, anti-lock brake system, direct ignition
system, airbag control system, wiper motors and air
conditioning systems that are susceptible to damage from
destructive voltage transients.
VA varistors offer excellent transient energy distribution and
requireꢀsignificantlyꢀlessꢀspaceꢀandꢀpadꢀareaꢀthanꢀsiliconꢀ
TVSꢀdiodes,ꢀofferingꢀgreaterꢀcircuitꢀboardꢀlayoutꢀflexibilityꢀ
for the designer.
