Performance Test:
| Test Item | Test Condition | Performance |
| Temperature coefficient | Test the resistance value at normal temperature and normal temperature added 100℃,calculate per℃ resistance value change rate . | ±300ppm/℃ |
| Short time overload | 1/2~4W:According 5 times rated voltage, 5~10W:According 10 times rated power to account the voltage or Max.overload voltage (get the lower) for 5 seconds. | ΔR≤±(2%R0+0.05Ω) |
| Pulse overload | At 4 × rated voltage or Max. pulse overload voltage (get the lower) cycle 10000±200 times(1 second on, 25 seconds off ). | ΔR≤±(1%R0+0.05Ω) |
| Resistance to soldering heat | Immerge into 350±10℃ tin stove for 2~3 seconds. | ΔR≤±(1%R0+0.05Ω) |
| Solderability | Immerge into 245±3℃ tin stove for 2~3 seconds. | The area of soldering is over 95% |
| Temperature cycling | At -55℃ for 30 min, then at +25℃ for 10~15 min, then at +125℃ for 30 min, then at +25℃ for 10~15 min, total 5 cycles. | ΔR≤±(1%R0+0.05Ω) |
| Load life in humidity | Overload rated voltage or Max.working voltage (get the lower) for 1000 hours (1.5 hours on and half-hour off ) at the 40±2℃ and 90~95% relative humidity. | ΔR≤±(5%R0+0.05Ω) |
| Load life in heat | Overload rated voltage or Max.working voltage (get the lower ) for 1000 hours (1.5 hours on and half-hour off) at the 70±2℃. | ΔR≤±(5%R0+0.05Ω) |
| Nonflammability | Respectively load AC voltage by 5,10,16 times rared power for 5 minutes. |
