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)

- Standard Type: 350 ppm
- Semi-fusing, Explosion-proof, High Surge Resistance Types: 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 Characteristic: 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 required from applying overload until fusing occurs.

Impact Resistance Performance
When switch K is closed and K2 is open, repeatedly switch K1 on/off for 2 seconds on/off for 2 seconds, for 100 cycles. The test resistor should not become open-circuited.
Note: 1. Capacitor C capacity is selected based on customer requirements; if not specified, C=10uF. 2. Resistor R value is selected based on the application circuit and converted to internal resistance. Resistor power is 20W, power factor is 0.8. Resistors below 10W generally use 20W, 5.1K (5%).
