Product Overview
Sprague's 10TC was a 1 kV ceramic disc line, though no Sprague catalog page for the series has been located. What this piece carries is on the body: the orange bullet-shaped disc is stamped 4.7D on the top line, N750 under it, 1KV under that, with a small nub of coating still on the crown. The listing calls the value 4.7 mf and the body prints 4.7 with a trailing D and no unit, so the listed wording stands here rather than a conversion we cannot support. Five on the shelf, sold each.
Key Features
- Value: the listing's own wording is 4.7 mf. The body prints 4.7D with no unit, so nothing here is restated as picofarads or microfarads
- Voltage: 1 kV, marked 1KV on the body
- Temperature coefficient: N750, marked on the body (EIA Class 1 temperature compensating, minus 750 parts per million per degree C, per Vishay's published TC code data)
- Catalog number: 10TCU-V47, from the listing's own name
- Marking string, verbatim from the body: 4.7D, N750, 1KV. No published Sprague key for the trailing D was located, so nothing is claimed from it
- Package: orange-coated ceramic disc, tall bullet profile with a small nub of coating at the crown
- Leads: two radial leads from the bottom edge, long and bent back on themselves 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
- Temperature compensation in LC oscillators
- Offsetting positive drift in tuned circuits and VFO tanks
- Trim and padding positions on nodes rated to 1 kV
- Alignment work on vintage transmitters and signal sources
Frequently Asked Questions
How many should I order? Order the count the build needs. Five 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.
What does the N750 on the body mean for my circuit? N750 is an EIA Class 1 temperature-compensating code: the capacitance falls by about 750 parts per million for every degree C the part warms up (per Vishay's published TC code data). That drift is deliberate rather than a fault, and it is why a part marked this way gets chosen for a tuned circuit that wanders the other way as it heats.
An orange bullet stamped 4.7D, N750, 1KV, still unsoldered and still honest about what it does not say.
