(range is application specific). Temperature rise is

approximately 40°C at rated rms current

• Solder reflow temperature: +260°C max for 10 seconds

max.

Packaging

• Supplied in tape and reel packaging,

4,150 parts per 13" reel

SD38 Series

Low Profile, Shielded Inductors

(1) Test Parameters: 100KHz, 0.100Vrms, 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.

De-rating is necessary for AC currents.

(3) Peak current for approximately 30% rolloff 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.

De-rating of the Irms is required to prevent excessive temperature rise.
