47 µH wirewound in a 1210 footprint
The LBC3225T470MR is a 47 µH wirewound inductor from Taiyo Yuden's LB, C Type series, rated for 220 mA continuous current with a 670 mOhm DC resistance. The unshielded construction and ±20% tolerance are typical for general-purpose wirewound inductors used in DC-DC converter input/output filters and low-frequency noise suppression.
Temperature range and self-resonant frequency
Operating from -40°C to 105°C, the inductor suits industrial and automotive ambient environments where board temperatures stay below the 105°C ceiling. With a self-resonant frequency of 10 MHz, it remains inductive up to that point; above 10 MHz the impedance becomes capacitive, so it is best applied in switching converters switching below a few MHz.
Taiyo Yuden lists the LBC3225T470MR as Active in production, so it remains a standard catalog item available through authorized distribution. The part is offered in Tape & Reel and Cut Tape packaging, making it straightforward to order for both prototyping and volume production.
