Vishay Technology EPIC: Bridge resistors target pyrotechnic applications

Offering joule-effect ignition for 50-µsec firing times, the EPIC (electropyrotechnic-initiator-chip) thin-film, or bridge, resistor suits pyrotechnic applications with a 70% no-fire/all-fire ratio. Resistive elements of the bridge resistors convert electrical energy into heat energy in an electrothermal profile for initiating a series of pyrotechnic events in a controlled energetic reaction. The EPIC resistors suit squib-header applications in automotive-safety systems for the deployment of air bags and other safety devices; military pilot-ejection systems, explosive-bolt disengagement of airborne missiles, chaff dispensers, artillery-projectile activators, and antitank mines; and mining and demolition systems. Prices for the EPIC resistors range from 20 to 50 cents.
