Wirewound inductor for signal filtering and DC-DC output chokes
The LBC2518T471KV is a wirewound inductor from Taiyo Yuden's LB, C Type series, offering 470 µH inductance in a compact 1007 (2518 Metric) surface-mount package. Rated for 50 mA with a maximum DC resistance of 28.6 Ohm, this unshielded inductor suits low-current signal filtering, DC-DC converter output chokes, and noise suppression in power supply rails where board space is tight.
The 470 µH inductance at 796 kHz test frequency and 3.5 MHz self-resonant frequency define the usable band — above SRF the inductor behaves capacitively, so this part is best for switching frequencies well below 3.5 MHz. The 50 mA current rating is the continuous DC limit at 25 °C ambient; the 28.6 Ohm DCR means a 50 mA load drops 1.43 V across the winding and dissipates 71.5 mW, which must be accounted for in the thermal budget of a dense PCB. Operating from -40°C to 105°C, the inductor covers industrial and automotive cabin environments, though the current derating above 85 °C should be checked against the application's worst-case ambient.
