Other Specifications
- Short-time Overload: No abnormalities when subjected to 2.5x rated voltage for 5 seconds. Resistance change rate within ±1% after 30 minutes cooling.
- Withstanding Voltage: No abnormalities or burning after applying 350V AC for 1 minute or max overload voltage for 1 minute. Resistance change rate within 0.5%.
- Insulation Resistance: ≥10000 MΩ (DC 500V).
- Damp Heat Life: Resistance change rate within ±5% after 500 hours at 40 ±2°C, 90-95% humidity.
- Load Life: Resistance change rate within ±5% after 1000 hours at 70°C.
- Solderability: Solder covers ≥95% of terminal area after immersion at 235 ±5°C for 2 seconds.
- Solder Heat Resistance: Resistance change rate within ±1% after immersion at 270 ±5°C for 10 ±1 seconds (or 350 ±10°C for 3.5 ±0.5 seconds).
- Non-flammability: No open flame when subjected to 8x rated current for 5 minutes.
- Usage Precautions: To avoid galvanic corrosion risk (approx. 10ppm defect rate after one year), limit usage to below 50V when ambient temperature and humidity exceed 85°C/85%.
