• 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.
