The Cooper Industries DR125-4R7-R is a shielded drum core inductor belonging to the DR Series. This component is designed for high power density and high efficiency applications.
Key electrical specifications include a nominal inductance of 0.47µH (tested at 100kHz, 0.25Vrms, 0.0Adc) with a +/-20% tolerance. It can handle a peak current of up to 33A (at 30% roll off) and has a typical DC resistance (DCR) of 0.0018 Ω at 20°C. The inductor is rated for a maximum total operating temperature of 125°C, with a storage and operating temperature range of -40°C to +125°C.
This inductor features magnetic shielding and secure mounting. It is supplied in tape and reel packaging, with 600 units per reel, and is designed for surface mounting. The solder reflow temperature is a maximum of +260°C for 10 seconds.
Applications for this series include DC-DC converters, noise filtering, and use in computer, DVD players, and portable power devices.
