Notes:

  1. The Hi-Pot test point is Wire to Core, and not more than 10uA at 600V / 5 Sec.
  2. The I-sat that will cause initial inductance value approximately 20% rolloff at 25°C ambient temperature.
  3. The I-rms that will cause temperature rise approximate 40°C without core loss.

Storage
  1. Temperature and humidity conditions: Less than 40℃ and 70% RH.
  2. Recommended products should be used within 6 months from the time of delivery.
  3. The packaging material should be kept where no chlorine or sulfur exists in the air.
Transportation
  1. Products should be handled with care to avoid damage or contamination from perspiration and skin oils.
  2. The use of tweezers or vacuum pick up is strongly recommended for individual components.
  3. Bulk handling should ensure that abrasion and mechanical shock are minimized.
