Product Overview
Sprague's 10TC was a 1 kV ceramic disc line, and this part still has its own paperwork with it: a small orange disc stamped NPO / 20-J / 1KV, photographed beside a Sprague carton label reading .000020 MF, 1000 VOLTS, plus or minus 5%, CAT. NO. 10TCC-Q20, TYPE NPO. That photographed label is what sets the value at 20 pF and corrects the 20 MF that had been riding on the old name. Seven on the shelf, sold each; what ships is the capacitor, not the label.
Key Features
- Capacitance: 20 pF, from the carton label reading .000020 MF photographed with this part; the body is stamped 20-J
- Voltage: 1 kV, marked 1KV on the body and 1000 VOLTS on that carton label
- Tolerance: plus or minus 5 percent, printed on the carton label shown
- Temperature coefficient: NPO, marked on the body and on the label (EIA Class 1, nominally 0 parts per million per degree C, per Vishay's published TC code data)
- Catalog number: 10TCC-Q20, printed on the Sprague carton label shown
- Marking string, verbatim from the body: NPO, 20-J, 1KV
- Package: orange-coated ceramic disc, roughly a quarter to five sixteenths of an inch across estimated against the rule in the photos, so treat that figure as approximate
- Leads: two radial leads from one edge, long and untrimmed as photographed
- No Sprague 10TC datasheet or catalog page was located, so verify against Vishay's published Class 1 ceramic data before designing in.
Applications
- Oscillator and tank circuit trimming in tube and RF gear
- Feedback and compensation positions needing a stable small value
- Coupling on high impedance nodes rated to 1 kV
- Vintage radio and test equipment restoration
Frequently Asked Questions
How many should I order? Order the count the build needs. Seven are on the shelf and they sell one at a time, so the order can be one piece or all seven. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
Why does the old paperwork say 20 MF? Because the Sprague carton label photographed with this part writes the value in microfarads: .000020 MF, which is 20 pF. Lose that decimal in a retype and you get the 20 MF that was sitting in this listing's name. The disc itself reads NPO / 20-J / 1KV.
Twenty picofarads, and a carton label that still spells the value out the long way.
