Specifications
TOLERANCE

For values > 1R0 - ±5%
For values < 1R0 - ±10% or ±0R05 or whichever is greater
For taped/adjustable/non-inductive values ±10%
Other tolerances on request

TEMP. COEFF.of RESISTANCE: 
[TCR]

±50ppm/°C - JSS limit = ±200ppm/°C : MIL limit = ±260ppm/°C
[in lower values higher TCR wires may be used]

POWER RATING:

Rated @ 70°C ambient and derated linearly to zero power at 350°c in horizontal or vertical mounting with blocked ends.

Max. voltage applicable as per specifications or ÖPR w hich ever is lower. In tapped resistors, the power handling capacity is reduced by approximately 10% per tap.

The power per tapped resistor will be in proportion to the length of the tap and the overall length of the resistor.

In adjustable resistors, power is proportional to the setting.

Design engineers should ensure that the dissipation does not exceed the ratings. the best method is to treat the full resistor as a current limited device and arrive at the maximum power for the value set.
