*1 When rated current is applied to the products, inductance will be within ±50% 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 As shown in the diagram below, derating is applied to the rated current based on the operating temperature.  
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
