Test Method
25°C (Measurement position: 10mm under from the case)
+25°C/-55°C and +25°C/+125°C (Application range; the straight style of 0.012Ω over)
Rated power x 2.5 for 5 seconds
260°C ± 5°C, 10 seconds ± 1 second
40°C ± 2°C, 90 - 95% RH, 1000 hours, 1.5 hr ON, 0.5 hr OFF cycle
70°C ± 2°C, 1000 hours, 1.5 hr ON, 0.5 hr OFF cycle
+125°C, 100 hours
After immersing the sample in I.P.A for 60 seconds ± 10 seconds,
the resistor surface should be rubbed with absorbent cotton 10 times
