Product Overview
Corning Glass Works GIL-271 fixed glass dielectric capacitor. 270pF capacitance, 500V rating, axial termination. The GIL designation refers to the Glass-In-Lead axial construction - a sealed format associated with high reliability and stable performance across temperature and frequency. CGW glass capacitors have a long record in audio, aerospace, and military electronics where drift and failure are not options.

- Makers and experimenters building or restoring high-voltage circuits where a reliable small-value cap matters
Frequently Asked Questions
What is the voltage rating on this capacitor?
500V. This matches confirmed ratings for 270pF Corning glass capacitors of this type. Some GIL series references cite 300 WVDC as a common standard - verify against your specific circuit requirements before installing.
What does the date code "431" indicate?
The "431" marking visible on the body is consistent with a date code format used on vintage components - not confirmed as a specific year without a datasheet, but typical for manufacturer lot or date tracking. The part is unused NOS regardless of production date.
Is a datasheet included?
Not included. A specific GIL-271 datasheet was not located. Buyers should verify capacitance, voltage, and physical dimensions against their circuit requirements before installation.
Are the leads solderable as-is?
Yes. Leads are straight, clean, and show no oxidation based on visual inspection. No pre-treatment should be needed for standard soldering.
Glass capacitors from Corning don't show up often in this condition - teal body intact, leads straight, never soldered. Wherever it goes next, it arrives ready.
