Product Overview
Sprague 10TCC-T10 Ceramic Disc Capacitor - 100 pF, 1000 VDC, NPO Temperature Characteristic
Condition
New, unused stock. The photographed piece is an orange dipped ceramic disc marked with a small maker's logo, NPO, 100J and 1KV. The coating is clean and unchipped, the printing is crisp, and both radial leads are straight, bright and free of solder, kinks or trimming. It is shown alongside the original Sprague Capacitors card, which reads .000100 MF, 1000 VOLTS, plus or minus 5 percent, CAT. NO. 10TCC-T10, TYPE NPO. That card is photographed for reference and provenance only. You are buying one capacitor; the label card is not included, and pieces beyond the one photographed may carry different date or lot markings.

Product Overview
This is a leaded ceramic disc capacitor from Sprague's 10TCC series, catalog number 10TCC-T10. The Sprague label states the value in the old microfarad convention as .000100 MF, which is the same value the body abbreviates as 100J: 100 picofarads at plus or minus 5 percent, rated 1000 volts. The dielectric is NPO, the class 1 temperature characteristic chosen when capacitance needs to hold steady as the chassis warms up rather than drift the way a general purpose Y5V or Z5U disc does. The radial leads suit through-hole board or terminal-strip work, and the 1 kV rating puts it in reach of tube-era plate circuits, snubbers and high-voltage coupling positions that a 50 V chip part cannot cover. Our records also cross-reference the Vishay and Cera-Mite line for this part; confirm any substitution against the current datasheet before you commit a build.
Key Features
- Catalog number: Sprague 10TCC-T10
- Capacitance: 100 pF, stated on the Sprague label as .000100 MF
- Tolerance: J, plus or minus 5 percent, confirmed on the label
- Voltage rating: 1000 VDC, marked 1KV on the body
- Temperature characteristic: NPO, marked on both the body and the label
- Construction: dipped ceramic disc, orange coating, radial leads
- Leads: straight, bright, uncut and unsoldered on the photographed piece
- Sold each, from a small remaining group of the same part
Applications
- Guitar amp technician replacing a failed 1 kV disc in a plate or tone circuit without dropping to a lower voltage rating
- Restorer rebuilding a tube radio or test set that expects a 100 pF NPO part in its original through-hole position
- RF hobbyist building a tuned stage where a stable, low-drift class 1 dielectric matters more than bulk capacitance
- Bench engineer adding a high-voltage snubber or coupling cap to a prototype on perfboard or a terminal strip
Frequently Asked Questions
Is this 100 pF or 100 microfarads?
100 picofarads. The Sprague card in the photo writes it the old way, .000100 MF, meaning 0.0001 microfarad, and the body carries the shorthand 100J. Both markings describe the same 100 pF part, and we have written the value out here exactly as the part and its label are marked.
What do NPO and the J after the value mean?
NPO is the class 1 temperature characteristic, the flat, low-drift dielectric used where capacitance must stay put across a temperature swing. J is the tolerance code for plus or minus 5 percent, and the Sprague label spells that same tolerance out as plus or minus 5 percent.
Do I get the Sprague label card shown in the photo?
No. One capacitor ships per unit purchased. The card is photographed so you can read the factory specification for yourself and see where the catalog number comes from, but it stays here.
Is this the same part as the Vishay or Cera-Mite equivalent?
The piece we are selling is marked and labelled as Sprague 10TCC-T10, and that is what we can confirm. Vishay and Cera-Mite appear in our cross-reference records for this part rather than on the capacitor. Not confirmed - check the equivalence against the current datasheet before you design it in.
Why buy the two or three pieces I actually need instead of a bag of 100?
Because a 100 pF NPO disc at 1 kV is a part you usually need in ones and twos: one for the amp on the bench, a spare for the drawer, maybe a third if the circuit is symmetrical. Bulk sellers force a hundred-piece bag for a repair that needs two, and the other ninety-eight sit in a bin for a decade. Here you take the exact count. Shipping is a flat $8, free once your order passes $28, so a couple of pieces added to a parts order costs less than the forced lot did, and orders leave our Idaho warehouse the same or next business day.
NPO ceramic earns its keep by refusing to change its mind when the chassis gets hot, which is exactly why a 100 pF at a thousand volts ends up in the spots where drift would be a service call. Count out what your board needs and put this orange disc back to work.
