*1 When rated current is applied to the products, inductance will be within ±30% of initial inductance value range.
*2 When rated current is applied to the products, temperature rise caused by self-generated heat shall be limited to 40°C
max.
*3 Keep the temperature (ambient temperature plus self-generation of heat) under 125°C.
4. Testing Conditions
Unless otherwise specified
Temperature: ordinary temperature (15°C to 35°C)
Humidity: ordinary humidity [25% to 85% (RH)]
In case of doubt
Temperature: 20°C±2°C
Humidity: 60% to 70% (RH)
Atmospheric pressure: 86 kPa to 106 kPa
