DR1040-100-R Description

Short technical summary and product information.

The DR1040-100-R is a low-profile, surface-mount shielded drum inductor from Cooper Industries, part of the DR1040 series. It offers a nominal inductance of 10μH with a ±30% tolerance, tested at 100kHz, 0.25V, and 0.0Adc. This inductor is designed for power applications, handling a rated RMS current of 9.6A (typical) and a saturation current of 3.8A (typical).

 

The component utilizes a ferrite core material and has a maximum DC resistance of 35mΩ at 20°C. It operates within a wide temperature range, from -40°C to +125°C, with a maximum total operating temperature of 125°C. The solder reflow temperature is rated at a maximum of 260°C for 10 seconds.

 

With dimensions of 10.3mm x 10.5mm x 4.0mm, this inductor is suitable for space-constrained applications. It is supplied in tape and reel packaging, with 850 units per reel. The DR1040 series is designed for applications such as notebook power, portable devices, wireless modems, and point-of-load power supplies.
