Dual function Varistor/Capacitor protects against voltage surges and high frequency noise...

NEW VARISTOR TECHNOLOGY FROM STACKPOLE
OFFERS SPACE AND COMPONENT COST SAVINGS

RALEIGH, NC (January 25, 2004) – Stackpole Electronics, Inc. has introduced a dual function device, 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 3V to 125V, and a by-pass capacitor operating in the capacitance range of 10nF to 1000nF. The MV Series is rated from –40ºC to +85ºC and exhibits excellent response times of less than 25ns.

The MV Series of varistors 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, 6mm x 9mm, with straight or crimped leads. The MV Series is able to withstand a single pulse surge current (Ip) of 150 amps (8/20 µsec waveform) and demonstrate single pulse energy absorption (Wmax) of 0.1 Joules to 2.5 Joules (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.

Regarding the use of the MV Series, Stackpole Director of Sales & Marketing’s, Rob Hudspeth commented, “The MV Series is a truly innovative design by our engineering group. This technology reduces component count and cost, two very important considerations in this age of efficiency.

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 is available in bulk, ammo pack, and tape and reel in 2000 piece quantities. Pricing for 2000 piece quantities is $0.25 each.
