Its 1.2 A continuous current rating and 186 mOhm max DCR make it a fit for DC-DC converter input and output filter stages where the inductor's own resistance directly affects conversion efficiency — a 1.2 A load through 186 mOhm drops about 223 mV and dissipates roughly 270 mW, which the 1210 package must sink into the board copper. ## Saturation headroom and self-resonant ceiling The saturation current (Isat) is specified at 1.6 A, giving about 33% headroom above the 1.2 A continuous rating — a margin that keeps the inductance from collapsing under transient peaks in a buck converter's inductor current. The self-resonant frequency of 40 MHz sets the upper bound for the switching frequency the inductor can handle before parasitic capacitance between windings turns the part capacitive; for a 2.2 MHz switcher, 40 MHz leaves about an 18× margin, so the inductor stays inductive well into the switching harmonics. ## Shielded construction for noise-sensitive layouts The magnetic shield contains the flux within the ferrite core, reducing radiated emissions into adjacent traces or sensitive analog circuitry — useful when the inductor sits near a low-noise regulator or a high-impedance ADC input on the same board.","metaTitle":"Murata LQH32PN4R7NNCL Shielded Wirewound Inductor, 4.7 µH","metaDescription":"Murata LQH32PN4R7NNCL drum core wirewound inductor, 4.7 µH ±30%, 1.2 A rated, 186 mOhm DCR, shielded, 1210 package.
