SD52 Series

A) Part Marking: Line 1: (1st digit indicates the inductance value per part marking

designator in chart above)

(2nd digit is a bi-weekly production date code)

(3rd digit is the last digit of the year produced)

Line 2: 52 (indicates the product size code)

Mechanical Diagrams

(1) Open Circuit Inductance Test Parameters: 100KHz, 0.25Vrms, 0.0Adc.

(2) RMS current for an approximate

∆T of 40°C without core loss. It is

recommended that the temperature of the part not exceed 125°C.

(3) Peak current for approximate 30% roll off at 20°C.

(4) DCR limits @ 20°C.

5) Applied Volt-Time product (V-uS) across the inductor at 100kHz necessary to

generate a core loss equal to 10% of the total losses for 40°C temperature rise.
