Product Overview
Published vendor listings put Sprague's 10TC as a 1 kV Class 1 ceramic disc line. This one is a temperature-compensating member of the group rather than an NPO: the orange bullet-shaped disc is stamped 3D on the top line, N220 under it, 1KV under that. That is the whole marking, and the 3D line carries no unit, so we repeat it here as it reads rather than converting it to a value. The listing has carried 3 mf and that wording stands until the reading is confirmed. Ten on the shelf, sold each.
Key Features
- Capacitance: stated as 3 mf in this listing. The body is marked 3D with no unit and we found no published Sprague 10TC catalog page to read it against, so no converted value is claimed here
- Voltage: 1KV as marked on the body
- Temperature coefficient: N220, marked on the body (EIA Class 1 temperature compensating, minus 220 parts per million per degree C, per Vishay's published TC code data)
- Catalog number: 10TCR-V30
- Marking string, verbatim from the body: 3D on the top line, N220 under it, 1KV under that. Nothing else is printed on the part, and we have no published Sprague key for the 3D line
- Package: orange-coated ceramic disc, tall bullet profile as photographed
- Leads: two radial leads from the bottom edge, long and untrimmed as photographed
- We did not locate a published Sprague 10TC datasheet, so verify against Vishay's published Class 1 ceramic data before designing in.
Applications
- Temperature compensation in LC oscillators and VFOs
- Drift correction on tuned circuits in warm chassis
- Small coupling values on nodes well under the 1KV marking
- Vintage transmitter and receiver alignment work
Frequently Asked Questions
How many should I order? Order the count the build needs. Ten pieces are on the shelf here, sold 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.
What does the N220 on the body mean for my circuit? N220 is an EIA Class 1 temperature-compensating code: the capacitance falls by about 220 parts per million for every degree C the part warms up (per Vishay's published TC code data). That is deliberate, not a defect.
N220 was Sprague's way of promising the drift would go the right direction on a hot chassis.
