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: 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: Refer to Figure 2. Rated power is the maximum value for continuous operation at 70. Power consumption derates according to the curve above 70.
- Fusing Characteristics: Defined as significant increase in resistance when overloaded, causing current to drop to below 1/50 of the initial test current. Fusing time is the duration from overload application to fusing.
- Fusing Time Requirements: Refer to Table 3-1 (General and High Lightning Surge Type), Table 3-2 (Explosion-proof Type), Table 3-3 (Semi-fusing Type). Fusing time can be customized upon request.
- Impact Resistance: Test according to Figure 3. Repeatedly switch K1 ON for 2S and OFF for 2S, 100 times. The test resistor should not become open-circuited.
