560 µH, 60 mA — the DC bias and SRF ceiling
The LQH32CN561K23L is a drum-core wirewound inductor from Murata's LQH32 series, offering 560 µH ±10% in an unshielded 1210 (3225 metric) surface-mount package. The self-resonant frequency is 5 MHz; above that the impedance becomes capacitive, so this inductor is a fit for DC-DC output filters and low-frequency EMI suppression below 5 MHz, not for switching noise above that point.
Unshielded construction and board coupling
No magnetic shield means the stray field couples into adjacent traces and components — keep sensitive analog or RF routing at least 2-3 mm away from the body, and avoid placing it directly under a switching FET or a high-impedance node.
