General Data
- Nominal resistance allowable deviation: 5%, 10%
- Climatic category: 55/155/21
- Low air 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-fuse 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 consumption is derated according to the curve when exceeding 70.
- Fusing characteristics: Defined as significant increase in resistance when subjected to specified overload, causing current to drop below 1/50 of initial test current. Fusing time is the time from application of overload until fusing occurs.
- Fusing time requirements under specified rated current overload multiples are detailed in tables 3-1, 3-2, and 3-3 (not fully provided).
- Impact resistance: Tested by repeatedly switching a circuit for 100 cycles (2s ON, 2s OFF). The resistor should not become open circuit.
