1. Open Circuit Inductance (OCL) Test Parameters: 1MHz, 0.1Vrms, 0.0Adc, 25°C
2. 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.
3. Isat: Peak current for approximately 30% rolloff at +25°C
4. BLK:-pf-(paInc=tdoKurc:*tUaLnsec*ed∆itIno. BµdHpe-pt):,e(G∆rmaI u(iPnseesa)B,kKp-tp:o(fKop-refacacoktrroeiprlpofrlsoesmc(usterarebelngetr),ainphA)m. ps). 5. Part Number Definition: MPI2520Rx-yyy-R
- MPI2520Rx = Product code and size - yyy = Inductance value in µH, R = decimal point,
if no R is present then third character = number of zeros. - “-R” suffix = RoHS compliant
