56 µH Wirewound Inductor for DC-DC Filtering and Signal Conditioning
The LQH32MN560K23L: Rated for 85 mA DC current with a maximum DC resistance of 4.9 Ohm, this unshielded inductor suits low-power filtering, DC-DC converter output chokes, and signal conditioning in portable or space-constrained designs.
Parametric Fit: Inductance, Current, and Self-Resonant Frequency
The 56 µH inductance is tested at 1 MHz, and the self-resonant frequency is 10 MHz — above this frequency the component behaves capacitively, so it must be kept below 10 MHz in the application. With a Q factor of 40 at 1 MHz, the inductor offers moderate efficiency at that frequency; the 4.9 Ohm DCR means conduction loss at 85 mA is roughly 35 mW, which is manageable in most low-power circuits.
