Product Overview
Equipped with dual parallel internal electrodes and flexible bare leads, this cold-cathode gas discharge indicator provides pilot lighting, relaxation timing, and reference discharge operation across classic instrumentation, audio gear, and electronic control circuits.
Key Features
- Dual parallel internal electrodes inside a sealed tubular glass capsule
- Flexible bare wire leads for direct circuit board soldering or point-to-point wiring
- Cold-cathode gas discharge operation
- Tubular envelope measuring approximately 20 mm body length
Applications
- Restoring status indicators in legacy audio amplifiers, communications gear, and bench equipment
- Assembling relaxation oscillators, stroboscopic triggers, or analog synthesizer modulation circuits
- Wiring vintage orange glow accents into custom maker enclosures and DIY electronics
Frequently Asked Questions
Does this lamp require an external series resistor?
Yes. Like all cold-cathode gas discharge tubes, a ballast resistor must be wired in series on standard line or DC supply rails to limit discharge current.
What industry standard cross-reference applies to the NE-68 designation?
The NE-68 cross-references to industry designation 5AC and military specification MIL-L-15098/2-001.
Nothing matches the warm, instant strike of a classic discharge capsule when the high-voltage rail comes alive. Solder it into the circuit and let that unmistakable gas glow get right to work.
