Rated for 270 mA with a maximum DC resistance of 1.2 Ohm, the part is sized for low-current supply rail filtering or signal-path decoupling where the DCR drop at full load stays under 325 mV — a figure to check against the downstream circuit's headroom. ## Self-resonant frequency and Q factor The self-resonant frequency is 31 MHz, which sets the upper bound for effective filtering — above this frequency the inductor behaves capacitively, so the part is best applied in switching regulators or LC filters switching well below 31 MHz. A minimum Q of 20 at 1 MHz indicates moderate energy storage efficiency at that test frequency — adequate for general-purpose DC-DC converter output filters but not optimised for high-Q tank circuits. ## Sourcing posture for the BOM line Available through independent distribution channels; pricing and lead time are confirmed at quote against the BOM quantity.","metaTitle":"Murata LQH32NZ4R7K23L Inductor, 4.7 µH, 270 mA, 1210","metaDescription":"Murata LQH32NZ4R7K23L wirewound ferrite core inductor, 4.7 µH ±10%, 270 mA, 1.2 Ohm DCR, AEC-Q200.
