Leaded Varistors
VM Dual Function Automotive Grade 125°C
Overview
Applications
KEMET's VM series of dual function protective devices
protect against voltage surges in an automotive voltage
region and against radio frequency noise. This component
replaces two components – a low voltage varistor and a
capacitor.
Typical applications include the protection against voltage
transients and suppression of radio-frequency interference
in automobile electronics including wiper motors, central
locking systems, seat adjustment motors, seat heating, and
electric window systems.
KEMET's VM series incorporate a varistor function in
automotive applications in a voltage region of 12 V,
24ꢀVꢀandꢀ42ꢀVꢀandꢀaꢀfunctionꢀofꢀaꢀradio-frequencyꢀfilteringꢀ
capacitor in a high capacitance range from 0.47 – 1.5 µF,
making them ideal for protection in automobile electronic
applications.
KEMET's VM series are square shaped components with in-
line leads and require at least 30% less mounting space.
