The self-resonant frequency is 100 MHz, meaning the inductor behaves inductively up to that point before the parasitic capacitance takes over. Below 100 MHz the impedance curve follows the expected 2πfL slope; above it the part looks capacitive and the filter or DC-DC converter loses attenuation. ## Footprint and board-fit — 1210 (3225 Metric) The nonstandard package designation means the pad layout follows the 1210 footprint — no special keep-out or thermal relief beyond the usual for a wirewound inductor. Unshielded construction means the magnetic field radiates into the surrounding board area. Keep a 0.5 mm keep-out zone around the part on adjacent layers to avoid eddy-current heating in nearby copper pours, especially under the inductor on inner layers. The base product number LQH32CH covers the full inductance range in this family. No pin-compatible direct second-source is listed, but the 1210 footprint is common across several Murata wirewound series — a parametric cross-check against the DCR and current rating is straightforward.","metaTitle":"Murata LQH32CH1R0M33L 1 µH Unshielded Wirewound Inductor","metaDescription":"LQH32CH1R0M33L from Murata Electronics: 1 µH ±20% wirewound drum core inductor, 1 A rated current, 60 mOhm DCR, 100 MHz SRF.
