• Buck, boost, forward, and resonant converters

• Noise filtering and filter chokes

Environmental Data

• Storage temperature range: -40°C to +125°C

• Operating temperature range: -40°C to +125°C

(range is application specific)

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

Packaging

• Supplied in tape and reel packaging, 1350 (DR73), 1100 (DR74),

600 (DR125), and 350 (DR127) per reel

(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-µS) across the inductor. This value represent the applied V-µS

at 100kHz necessary to generate a core loss equal to 10% of the total losses for 40°C

temperature rise.

6) Part number definition: DRxxx-yyy-R

DRxxx = product code and size,

-yyy = inductance value in µH,

R = decimal point. If no R is present, third character = # of zeros

-R suffix = RoHS compliant
