General Data
- Nominal Resistance Tolerance: 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-fusing type, explosion-proof type, high lightning surge type: 35001500 ppm - Rated Current: I(A) = P(W)/R()
- Derating Curve: Refer to Figure 2. Rated power is the maximum continuous operating value at 70. Power derating is required above 70.
- Fusing Characteristic: Defined as the significant increase in resistance when subjected to specified overload, causing the current to drop below 1/50 of the initial test current. Fusing time is the duration from the application of overload until fusing occurs.
- Requirements: Fusing time under specified rated current multiples of overload should comply with the table.
- Standard and High Lightning Surge Types: See Table 3-1.
- Explosion-proof type: See Table 3-2.
- Semi-fusing type: See Table 3-3.
- Fusing time can be customized upon user request. - Impact Resistance: According to Figure 3, repeated switching of switch K1 (ON for 2S, OFF for 2S) for 100 cycles should not result in an open circuit.
- Capacitor C selection based on customer requirements; default C=10uF if not specified.
- Resistor R value selected based on the circuit, converted to internal resistance; power rating 20W, power factor 0.8. For resistors under 10W, typically use 20W, 5.1K (5%).
