Effective August 2017

SD

Low profile metalized shielded drum core power inductors

Product specifications

(1) Open Circuit Inductance Test Parameters: 100 kHz, 0.25 Vrms, 0.0

Adc.

(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) SD10,12,18,25 Peak current for approximate 30% rolloff at +20 °C.

SD14 Peak current for approximate 20% roll off at

+20 °C.

(4) DCR limits @

+20 °C.

5) Applied Volt-Time product (V-u

s) across the inductor at 100 kHz necessary to

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