Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.250 Vrms, 0.0 Adc 3. Peak current for approximately 30% roll-off 20 C 2. Irms: DC current for an approximate temperature rise of 40 C without core loss. Derating is necessary 4 Part Number Definition: UP0.4C-xxx-R for AC currents. PCB layout, trace thickness and width, air-flow, and proximity of other heat generating UP0.4C= Product code and size components will affect the temperature rise. It is recommended that the temperature of the part xxx= Inductance value in H, R= decimal point, if no R is present then last character equals number of zeros not exceed 125 C under worst case operating conditions verified in the end application. -R suffix = RoHS compliant 5.
