1 / 6 page DR Series High Power Density, High Efficiency, Shielded Inductors 1207 BU-SB07327 Page 1 of 6 Data Sheet 4315 Description • 125°C maximum total operating temperature • Four sizes of shielded drum core inductors • Inductance range from 0.33µH to 1000µH • Current range up to 56 amps peak • Magnetic shielding • Secure mounting • Ferrite core material Applications • Computer, DVD players, and portable power devices • LCD panels • DC-DC converters • 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 Part Number Rated OCL(1) Irms(2) Isat(3) DCR(4) Volt-µSec(5) Inductance +/-20% Amps Amps (Ω Ω ) Typ. (µH) (µH) Peak Typ.
