Other Specifications

  • Lead Strength (Tensile): 1.5kg for 10 seconds without detachment or looseness.
  • Lead Strength (Torsion): Withstand specified torsion without breakage or looseness.
  • Short-time Overload: No abnormality when 2.5x rated voltage is applied for 5 seconds. Resistance change within 1% after cooling.
  • Withstand Voltage: 350V AC for 1 minute. No abnormality or burn damage. Resistance change within 0.5%.
  • Insulation Resistance: 10000M (DC 500V).
  • Damp Heat Life: Resistance change within 5% after 500 hours at 402, 90-95% RH.
  • Load Life: Resistance change within 5% after 1000 hours at 70 with rated power applied cyclically.
  • Solderability: Solder coverage 95% on terminal area after immersion in 2355 tin bath for 2 seconds.
  • Solder Heat Resistance: Resistance change within 1% after immersion in 2705 tin bath for 101 seconds (or 35010 for 3.50.5 seconds).
  • Non-flammability: No open flame when 8x rated current is applied for 5 minutes.

Application Notes

  • To avoid risk of galvanic corrosion (approx. 10ppm failure rate after one year of use), limit usage to below 50V when ambient temperature and humidity exceed 85/85%.
