Stackpole Electronics Intros MV Series Varistor/Capacitor


New Products Mar 17, 2005 by Jeff Shepard

Stackpole Electronics Inc. (SEI, Raleigh, NC) introduced its new dual-function MV Series, which protects electronic equipment operating in a low-voltage region against voltage surges and high-frequency noise, replacing two components -- a low-voltage varistor and a capacitor. The MV Series incorporates a varistor in the dc voltage range from 3 V to 125 V, and a by-pass capacitor operating in the capacitance range of 10 nF to 1,000 nF. The MV Series is rated from –40 °C to +85 °C, and exhibits response times of less than 25 ns.

Applications for the MV Series include electrostatic surge absorption, relay surge suppression effect and relay reset time, and piezoelectric buzzer shock noise absorption. The MV Series are square-shaped components with in-line leads, requiring at least 30% less mounting space than the two components they replace. They are available in one size, 6 mm x 9 mm, with straight or crimped leads. The MV Series is able to withstand a single pulse surge current of 150 A (8/20 µsec waveform) and demonstrate single pulse energy absorption of 0.1 J to 2.5 J (10/1000 µsec waveform). The MV Series is intended for protection of all sensitive electronic devices experiencing both voltage transients and high-frequency noise produced by electromechanical devices, such as buzzers and relays.

The MV Series is available in bulk, ammo pack, and tape and reel in 2,000-piece quantities. Pricing for 2,000-piece quantities is $0.25 each.
