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:
- General 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 power at 70. Power derating is required above 70 according to the curve.
- Fusing Characteristics: Defined as significant increase in resistance when subjected to specified overload, causing current to drop below 1/50 of the initial test current. Fusing time is the time from applying overload to fusing.
- Requirements: Fusing time must comply with the table under specified rated current multiples overload conditions. - Impact Resistance: Tested by repeatedly switching on and off a switch for 100 cycles (2S on, 2S off). The resistor should not become open-circuited.
