EPC-505
PLUG-TYPE ELECTRIC IGNITER
PRODUCT OVERVIEW
A compact, low-voltage igniter for fuze applications. Thin-film Electro-Pyrotechnic Initiator Chips (EPIC) provide repeatable ignition without the mechanical fragility of conventional bridge-wire structures.
KEY FEATURES
- Thin-film EPIC electro-thermal ignition
- Dual chips in parallel for redundancy
- Defined All-Fire / No-Fire characteristics
- High immunity to ESD and unintended stimuli
- Direct drive from low-voltage SMPS outputs
- Hermetic, glass-to-metal sealed 2-pin interface
