Product Overview
The TS line is Tepro's axial precision power wirewound family, a steatite or alumina core wound in copper-nickel or nickel-chrome under a high-temperature silicone seal, per Tepro's published TS series data. The unit photographed is stamped on four lines down a small matte black cylinder: TEPRO, then TS1, then 5 0.05%, then 9317; the 9317 is a stamped code, and Tepro's published data offers no reading for it. It is held between fingertips in the photos, which gives the honest scale - the body is about the size of a fingernail, with bright tinned leads several times its length running straight out both ends. Sixteen are on the shelf at this value, sold one at a time.
Key Features
- Body of the unit photographed stamped TEPRO TS1 with 5 0.05% and the code 9317, giving 5 ohm at 0.05% tolerance
- TS1 is a 1 W type published as covering 0.01 to 20K ohm (Tepro published TS data)
- Axial precision power wirewound with high-temperature silicone sealant and tinned copper-weld standard terminals (Tepro published TS data)
- TS standard tolerances span 0.05% to 5%, with 0.01% offered on most types as a variation (Tepro published TS data)
- Temperature coefficient +/-50 ppm across the 1 to 9.9 ohm range, special TC to +5 ppm offered on request (Tepro published TS data)
- Rated on characteristic U with a 275 degC maximum hotspot and 0.5% maximum delta-R over 2000 h load life (Tepro published TS data)
- Short-time overload of 5 s at 5x rated power on 3 W and smaller types (Tepro published TS data)
- Verify against Tepro's published TS series data before designing in.
Applications
- Bridge legs and ratio arms in measurement circuits
- Calibration and reference resistance standards
- Low-value shunts where the reading has to be trusted
- Test fixtures and lab instrument rebuilds
Frequently Asked Questions
How many should I order?
Order the count the build needs. Sixteen of this value are on the shelf, sold one at a time, so a fixture wanting three or four matched legs fills from this listing in one order. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
Is 0.05% a stock tolerance here, or a special order?
Tepro's published TS data lists 0.05% to 5% as the standard tolerance range, so the 0.05% stamped on this body is the tight end of standard rather than a special, and tolerances to 0.01% are published as an available variation on most types. The stamp on the unit photographed carries the type, the value, the tolerance and the 9317 code and nothing else visible in these photos, so if a purchasing system wants a longer ordering code you will be assembling it from TS1, 5 ohm and 0.05%.
Five ohms held to half a thousandth, small enough to lose in a palm and steady enough to check a meter against.
