1. Open circuit inductance (OCL) test parameters: 100 kHz, 0.25 Vrms, 0.0 Adc, +25 °C 

2. Full load inductance (FLL) test parameters: 100 kHz, 0.25 Vrms, Isat, +25 °C 

3. Isat: Peak current for approximately 20% rolloff @ +25 °C 

4. Part number definition: LD2-xxx-HV 

- LD2 = Product code 

- xxx= Inductance value in μH, R=decimal point 

- -HV suffix = High voltage capability 

5. Irms: DC current for an approximate temperature rise of 40 °C without core loss. Derating is necessary for AC currents. PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed +125 °C under worst case operating conditions verified in the end application
