It is rated for 1.2 A continuous current with a DCR of 186 mOhm max, making it a fit for input/output filtering on buck converters or as a supply rail choke in portable equipment. The 1210 (3225 Metric) footprint and 1.70 mm seated height suit it for space-constrained PCB layouts where a shielded inductor is needed to contain magnetic flux from adjacent traces or components. ## Current handling and saturation margin Rated current is 1.2 A, while the saturation current (Isat) is 1.6 A — a 33 % headroom above the continuous rating. This margin means the inductor can tolerate transient current spikes without a catastrophic drop in inductance, which is important for DC-DC converters during load steps or startup. The self-resonant frequency of 40 MHz is well above typical switching frequencies for point-of-load converters (1–4 MHz), so parasitic self-resonance does not interfere with normal filtering operation. With a ±30 % tolerance on the nominal 4.7 µH value, the actual inductance can vary from 3.29 µH to 6.11 µH. This is typical for ferrite-core power inductors and should be accounted for in the control-loop compensation of a regulator. ## Operating range and board integration The ferrite core material maintains stable inductance across this range, though DCR will increase with temperature per the copper winding's positive temperature coefficient. Packaged in Tape & Reel (TR) with Cut Tape (CT) options, the inductor is compatible with standard pick-and-place assembly. The 1210 (3225 Metric) footprint uses a common land pattern; no special pad geometry is required beyond the manufacturer's recommended layout.","metaTitle":"Murata LQH32PZ4R7NNCL 4.7 µH Shielded Inductor, 1.2 A","metaDescription":"Murata LQH32PZ4R7NNCL wirewound inductor, 4.7 µH, ±30%, 1.2 A rated, 186 mOhm DCR, shielded ferrite core, 1210 package.
