Product Overview
Sprague's 10TC was a 1 kV ceramic disc line, though no Sprague catalog page for the series has been located. What is certain about this piece is what the body carries: a circled Sprague logo mark with a small numeral on the top line, then 50J, then NPO, then 1KV, pressed into orange coating. The live listing calls the value 5 mf; the disc prints 50 with no unit beside it, so the digits do not match the name either, and the listed wording stands here rather than a conversion we cannot support. Thirteen on the shelf, sold each.
Key Features
- Value: the listing's own wording is 5 mf. The body prints 50J with no unit, so nothing here is restated as picofarads or microfarads
- Voltage: 1 kV, marked 1KV on the body
- Temperature coefficient: NPO, marked on the body (EIA Class 1, nominally 0 parts per million per degree C, per Vishay's published TC code data)
- Catalog number: 10TCC-050, from the listing's own name
- Marking string, verbatim from the body: circled logo mark with a small numeral, 50J, NPO, 1KV
- Package: orange-coated ceramic disc, teardrop profile with a small nub of coating at the top edge
- Leads: two long radial leads from one edge, splayed and untrimmed as photographed
- No Sprague 10TC datasheet or catalog page was located and no carton label was photographed with this part, so verify the value against Vishay's published Class 1 ceramic data, or on a meter, before designing in.
Applications
- Tuned and tank circuits in tube-era radio gear
- Oscillator padding where a stable Class 1 dielectric matters
- Coupling and bypass on nodes rated to 1 kV
- Restoration of vintage transmitters and instrument chassis
Frequently Asked Questions
How many should I order? Order the count the build needs. Thirteen are on the shelf and they sell one at a time. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
The listing says 5 mf and the disc says 50J. Which is right? We are not going to guess for you. The body prints 50J with no unit, the listing says 5 mf, and the digits themselves disagree, so this is not a tidy unit mix-up anyone can quietly correct. No Sprague 10TC catalog page was located and no carton label was photographed with this piece, so the listed wording stands and the body reading is printed above for you to judge. If the value has to be certain, meter it on arrival; returns are no-hassle.
One orange disc, stamped 50J, NPO, 1KV, and a value we would rather leave open than pretend to know.
