Rated DC current is 125 mA; the maximum DC resistance is 3.1 Ohm. In a buck-converter output filter, the I²R loss at full rated current is about 48 mW — negligible for the 1210 footprint, but the DCR also sets the low-frequency impedance divider with the load. Self-resonant frequency is 13 MHz, and Q factor is 35 at 1 MHz. Above SRF the inductor behaves capacitively, so the useful filtering band stops well below 13 MHz — a consideration for any switching regulator switching above 2–3 MHz. ## Drum core, wirewound, unshielded — construction trade-offs Drum-core wirewound construction with a ferrite core and no magnetic shield means the flux field extends beyond the component body. Adjacent traces carrying high-di/dt signals should be kept at least one component width away to avoid parasitic coupling. The unshielded body has no top-side metal, so pick-and-place nozzle clearance is straightforward. ## Temperature grade covers automotive and industrial ambient Operating range is -40°C to +105°C — the full automotive Grade 3 temperature band and the common industrial ambient envelope. No derating is required at 85°C ambient, but above 105°C the part is outside its rated operating range.","metaTitle":"Murata LQH32NZ270J23L 27 µH Inductor, 125 mA, 1210","metaDescription":"Murata LQH32NZ270J23L drum core wirewound inductor, 27 µH ±5%, 125 mA, 3.1 Ohm DCR, AEC-Q200, 1210 SMD.
