Ignitor Chip

DZ Series

The Ohmite DZ series is an element resistor desinged to be used with Electro-Pyrotechnic systems. This SMD chip replaces traditional bridge wires. When compared to a traditional bridge wire, the ignitor resistor can accurately control the ignition time of the detonator. The ignitor resistor is the most critical factor that determines whether the entire digital electronic detonator can be successfully ignited. The Ohmite ignitor chip is available in multiple values for use with varying devices and set-ups.


  • SMD design using alumina substrate
  • Heat insulating layer to assit in "No Fire" safety
  • Peak surface temp of 500°C for ignition
