- PDF pages: 2
Technical content
Features
- RoHS compliant
- Ceramic chamber for ultimate reliability.
- Very high switching speed once switching voltage has been reached, resulting in high di/dt to be generated enabling the best performance to be extracted from ignition transformers.
- Tape and reel to EIA 481-1
Applications
- For switching stored electrical energy (such as capacitive discharge) at predetermined voltages.
- Designed for ignition circuits used in high pressure HID lighting.
