Parametric overview for BOM fit
The LQH32CH1R0M53L is a 1 µH wirewound inductor in Murata's LQH32 series, rated for 1 A continuous with a 60 mΩ DC resistance. The 100 MHz self-resonant frequency keeps the inductive impedance intact well into the VHF band — useful for decoupling or filtering in power rails switching at a few MHz where the SRF margin avoids capacitive roll-off. The unshielded ferrite-core construction means the magnetic field extends beyond the component body. In a dense layout, keep a 1–2 mm keep-out zone around the inductor to avoid coupling into adjacent traces or low-level analog loops.
The nonstandard case code means the pad layout follows the 1210 footprint — standard reflow profiles for a ferrite-core inductor apply, with a peak temperature of 260 °C for lead-free solder.
The 85 °C ceiling limits it to cabin or protected indoor environments; for 105 °C or 125 °C applications, look at the LQH32P or LQH43 series.
