Performance Characteristics
Test
Performance or Quality Acceptance
R < 100KΩ: -500 ~ +350ppm/ºC
100KΩ ≤ R < 1MΩ: -700 ~ 0ppm/ºC
R ≥ 1MΩ: -1500 ~ 0ppm/ºC
Test Condition and Method
Measure resistance (R0) at room temperature (t),
after that, measure again the resistance (R) at
100ºC higher than room temperature.
TCR - Temperature Coefficient of Resistance
Overload (Short Time)
Change of resistance
≤±(0.75% + 0.05Ω)
Apply the 2.5 times rated voltage or max overload
voltage whichever is lower for 5 seconds and leave
in room temperature for one hour after test.
In the chamber having temperature 40±2ºC and
relative humidity 93±3%, apply one percent of the
power rating, 1.5 hour ON, 0.5 hour OFF for
1000 hours and leave in room temperature for
one hour after test.
At 70±2ºC, apply rated DC voltage 1.5 hour ON,
0.5 hour OFF for 1000 hours and leave in room
temperature for one hour after test.
121ºC, 2atm, 98-100% R.H.
Apply the rated DC voltage for 100 hours.
Damp heat (Steady State)
Change of resistance
R < 100KΩ: ≤±(3% + 0.05Ω)
R ≥ 100KΩ: ≤±(5% + 0.05Ω)
Change of resistance
R < 100KΩ: ≤±(2% + 0.05Ω)
R ≥ 100KΩ: ≤±(3% + 0.05Ω)
Change of resistance
≤±(20% + 0.05Ω)
