Resistance Range:
1 Ohm to 10 M Ohms
for
E24
values(5%)
1 Ohm to 1 M Ohms for E96 values(1%)
Rated Power:
1/16 to 1W
at 70°C
(Please see Power
Derating Curve)
Rated Voltage:
Rated Power x Nominal Resistance.
Overload Voltage:
Please refer to
Power Ratings
Table.
Temperature Coefficient:
±
100 ppm or ±
200 ppm per °C.
Temperature Range:
-55°C to +125°C with derating above 70°C
Tolerance:
± 5%
or
±1%
(Special tolerance upon
request.).
Load Life:
The component will be subjected to 1000 hours of testing at rated
voltage and 70° C, with duty cycles of 1.5 hours ''on'' and 0.5 hours ''off''.
After the test the Resistance change will remain within ±3% of the initial
value + 0.1 Ohm for values above 1 M Ohm and 5% for values less than
1 M Ohm.
Resistance to Soldering Heat:
The component can be subjected to a soldering temperature of 270 °C
for 10 seconds. After the test the Resistance change will remain within
±3% + 0.1 Ohms.
