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.
