General Data
- Nominal Resistance Tolerance: 5%, 10%
- Climatic Category: 55/155/21
- Low Pressure: 8.5kpa
- Stability Grade: 5%
- Resistance Change Limit:
- Long-term Test: (5%R+0.1)
- Short-term Test: (1%R+0.05)
- Temperature Coefficient: Regular type 350 ppm; Semi-fusing type, explosion-proof type, high lightning surge type: 35001500 ppm
- Rated Current: I(A) = P(W)/R()
- Derating Curve: Rated power is the maximum value for continuous operation at 70. Power derating is required above 70 according to the curve.
- Fusing Characteristics: Defined as a significant increase in resistance when subjected to specified overload, reducing the current to below 1/50th of the initial test current. Fusing time is the duration from applying overload until fusing occurs.
- Impact Resistance: Tested by repeatedly closing and opening switch K1 for 100 cycles (2s ON, 2s OFF). The test resistor should not become open-circuited.
Main Test Items, Methods, and Performance Requirements
