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: Standard 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 continuous operating value 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 1/50 of the initial test current. Fusing time is the duration from applying overload to fusing.
- Impact Resistance: Test involves repeatedly switching a circuit for 100 cycles (2S on, 2S off) to ensure the resistor does not open circuit.
