Introduction

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. KEMET's VM series incorporate a varistor function in automotive applications in a voltage region of 12 V, 24 V and 42 V and a function of a radio - frequency filtering capacitor in a high capacitance range from 0.47 to 1.5 μF, making them ideal for protection in automobile electronic applications. KEMET's VM series are square shaped components with inline leads and require at least 30% less mounting space.

Features

• Through - hole form factor
