SDR0403-120ML Description

Short technical summary and product information.

The Bourns SDR0403-120ML is a surface mountable, unshielded fixed inductor from the SDR0403 series. It offers a nominal inductance of 12µH with a tolerance of ±20% and a rated current of 1.05A. The DC resistance is a maximum of 210mOhm, and it has a saturation current of 1.6A.

 

This drum core, wirewound inductor operates within a temperature range of -40°C to 125°C. Its compact dimensions, with a height of 3.50mm and a footprint of 4.50mm x 4.00mm, make it suitable for space-constrained applications. The inductor is designed for input/output filtering in DC/DC converters and power supplies for portable communications equipment, camcorders, and LCD TVs.

 

Key electrical characteristics include a Q factor of 28 at 2.52MHz and a self-resonant frequency of 30MHz. The ferrite core material contributes to its performance in power applications. It is supplied in tape and reel packaging for automated assembly processes.
