Product Overview
Xenon Strobe Flash Tube Trigger Coil — Encapsulated 3-Pin Through-Hole, Wire Secondary Lead
Condition
Single unit available. Unused NOS — stored in bulk in a private maker's workshop estate, with cosmetic scuffs and scratches on the encapsulated body from storage. Evaluation: Visual inspection only. Function testing not performed. No original packaging.
Ships same business day from Idaho. Packed carefully.
Product Overview
Unbranded encapsulated trigger coil transformer with a 3-pin through-hole primary and a white wire secondary lead. Trigger coil transformers produce a high-voltage ionization pulse that fires a xenon flash tube — without this pulse, the tube will not conduct. Three pins mount through a PCB on the primary side; the wire lead connects to the flash tube's trigger electrode.
Key Features
- 3-pin through-hole primary configuration
- White wire secondary lead — rated 300V continuous working voltage
- Fully encapsulated body — potted construction
- Output voltage (kV): Not confirmed — verify against circuit requirements before use
- Trigger type (external vs. series injection): Not confirmed
Applications
- Photographic speedlight and studio strobe repair
- Industrial and warning strobe light servicing
- Xenon flash circuit construction — hobbyist and maker projects
Frequently Asked Questions
What is the output voltage of this trigger coil?
Not confirmed. No brand, part number, or datasheet is available for this unit. Output voltage for trigger coils typically ranges from 4 kV to 20 kV or higher depending on the original application. Verify your circuit's trigger voltage requirement before use.
Is this an external trigger or series injection type?
Not confirmed. The 3-pin primary plus single wire secondary configuration is consistent with external triggering, where the wire wraps around or contacts the flash tube's trigger electrode — but this has not been verified. Evaluate the pinout and construction against your circuit before installation.
What does the 300V marking on the wire mean?
The 300V rating is the continuous working voltage of the wire's insulation. Trigger coil secondary pulses are extremely brief — microseconds — so the wire can handle transient voltages well above its continuous rating. This is standard for trigger coil wire leads.
Are there any inclusions — packaging, datasheet, or mounting hardware?
No. This unit is sold bare — no packaging, no datasheet, no mounting hardware included. It came to us from the estate of a private maker's workshop.
Intended for experienced builders and technicians who can evaluate an unbranded component against their own circuit requirements. If output voltage, turns ratio, or trigger type must be confirmed before purchase, this unit is not the right fit.
