Introduction

KEMET's VK series of dual function protective devices protect against voltage surges in a low voltage region and against high frequency noise, replacing two components, those being a low voltage varistor and a capacitor. KEMET's VK series incorporate a varistor function in the DC voltage range from 3 to 125 V (up to 170 V upon request) and function as high frequency by-pass capacitors operating in the capacitance range from 10 nF to 1 µF. Lower capacitance values are also available. They are intended for protection of all sensitive electronic devices experiencing both voltage transients and high frequency noise produced by electromechanical devices, such as buzzers, relays, etc. KEMET's VK series are square shaped components with inline leads and require at least 30% less mounting space.
