Vitreous Enamelled Heavy Duty Tape wound Resistors
Vintage ‘Milspec’ part Nato NSN No. 10W 5905 99 7202860
1R0 (1 Ohm) 10% 125W @ 20’C
GENERAL INFORMATION
The U400 Series of resistors is particularly suitable for overload applications, due to the large energy absorption capability of the heavy tape element and careful matching of tube and enamel thermal characteristics. The Welwyn range is based on six sizes of tube, each of which has a recommended dissipation which limits operating surface temperature to a maximum of 350°C. The resistors may be fitted with tapping bands as required; these may also be used as adjusting bands. Please Note! These are not supplied here!
CONSTRUCTION
The stability and reliability of this range of resistors
result from the use of best quality materials in the
construction. A high purity ceramic tube is matched
with nickel chromium or copper nickel alloy
resistance tape and specially formulated enamel,
ensuring the resistors withstand repeated heat
cycling without damage. Connections between the
resistance element and terminations are welded;
other connections are brazed. Ferrules are anchored
into the tubes with high temperature adhesive.
TERMINATIONS
Ferrule, electrically live Nickel plated brass. Denoted by prefix ‘UC’ thus: UC414.

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large distribution Co. and have been kept in storage for a time, we have therefore classified them as ‘new other’, they are however pristine, stored with us sealed in original packaging and in good serviceable condition, the photographs are representative of their general appearance, being of some of our actual stock, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
