In a buck converter, 22 µH at 250 mA supports output currents up to that limit before the core saturates or the temperature rise exceeds the ferrite's margin — the 710 mOhm DCR will drop about 178 mV at full load, so factor that into the output voltage budget for a low-voltage rail. ## Self-resonant frequency and layout note The self-resonant frequency is 19 MHz — above that the inductor's impedance becomes capacitive, so keep switching noise below that ceiling. The unshielded construction means the magnetic field radiates; keep sensitive analog traces or high-impedance nodes at least a few millimeters away from the body.","metaTitle":"Murata LQH32CH220K53L 22 µH Unshielded Wirewound Inductor","metaDescription":"Murata LQH32CH220K53L 22 µH unshielded wirewound inductor, 250 mA, 710 mOhm DCR, 1210 package.

At 250 mA, the resistive loss is about 44 mW — acceptable for most designs, but in a battery-powered rail every milliohm counts toward efficiency. The voltage drop across the DCR also shifts the output regulation point in a converter."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH32CH220K53L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH32CH220K53L when reusing this data.
