Moisture Resistant Carbon Film Resistor Resistive Product Solutions Performance Characteristics Item Performance or Quality Acceptance Test Condition and Method TCR - Temperature Coefficient of Resistance R < 100K: -500 ~ +350ppm/C 100K R < 1M: -700 ~ 0ppm/C R 1M: -1500 ~ 0ppm/C Measure resistance (R0) at room temperature (t), after that, measure again the resistance (R) at 100C higher than room temperature. 6 10 R-R0 TCR = x (ppm/C) R0 (t + 100)-t Overload (Short Time) Change of resistance (0.75% + 0.05) 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. Damp heat (Steady State) Change of resistance R < 100K: (3% + 0.05) R 100K: (5% + 0.05) In the chamber having temperature 402C and relative humidity 933%, 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. Change of resistance R < 100K: (2% + 0.05) R 100K: (3% + 0.05) Change of resistance (20% + 0.05) Load Life Pressure Cooker Bias Test At 702C, 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. 121C, 2atm, 98-100%RH. Apply the rated DC voltage for 100 hours.
