22 µH wirewound inductor for power and signal filtering
The Taiyo Yuden LBC2518T220KV is a 22 µH wirewound inductor in the LB, C Type series, housed in a 1007 (2518 Metric) surface-mount package. Rated for 250 mA continuous current with a maximum DC resistance of 1.001 Ohm, it suits low-to-moderate current DC-DC converter output filters and power supply decoupling stages where the 22 µH value sets the ripple current. The self-resonant frequency of 19 MHz defines the upper frequency limit before parasitic capacitance causes the impedance to fall — stay below this in switching converters to keep the inductor behaving as an inductor.
Unshielded construction and temperature range
Unshielded construction means magnetic flux radiates from the core — board layout should keep sensitive traces or other magnetics at least one package width away to avoid coupling. Inductance is tested at 2.52 MHz, a common test frequency for this value range, ensuring the measurement reflects the core material's permeability at a representative switching frequency.
