22 µH wirewound inductor for DC-DC filtering and bias-T circuits
The LBC2518T220MV is a 22 µH wirewound inductor from Taiyo Yuden's LB, C Type series, rated for 250 mA continuous current with a maximum DC resistance of 1.001 Ohm. Its self-resonant frequency of 19 MHz sets the upper bound for effective filtering — above this frequency the inductor behaves capacitively, so it is best suited for switching regulators and bias-T networks operating below 10 MHz. The unshielded construction means the magnetic field is not contained within a ferrite shield — adjacent traces or components within a few millimeters may couple noise, so layout separation is required in dense power rails.
