Its 790 mA current rating and 97 mΩ DCR place it in the low-to-mid current range for a 1210 (3225 metric) footprint — the DCR at 97 mΩ means a 60 mV drop at full rated current, which is the conduction loss the board's copper pour has to sink. The self-resonant frequency is 64 MHz — well above the 1 MHz test frequency, so the inductor behaves as a pure inductance up through the low-MHz switching range typical of buck converters and filter networks. The unshielded construction means the external field fringe couples into adjacent traces; keep a keep-out zone under the part on the inner layers if EMI is a constraint. ## Temperature floor and board-fit The ferrite core material saturates gradually above the rated current; the 790 mA figure is the heating-current limit, not the saturation current, which is typically higher in the LQH32 series. The unshielded body means no magnetic shield layer — the part's inductance changes less with DC bias than a shielded equivalent, but the radiated field is higher.","metaTitle":"Murata LQH32CH2R2M53L 2.2 µH Unshielded Inductor, 790 mA","metaDescription":"Murata LQH32CH2R2M53L drum core wirewound inductor, 2.2 µH ±20%, 790 mA rated current, 97 mΩ DCR.
