Its 530 mA current rating and 216 mOhm max DCR define the usable load range — the DCR sets the I²R conduction loss, so at full rated current the self-heating adds roughly 60 mW to the thermal budget. ## Unshielded drum core — when the self-resonant frequency matters more than shielding The unshielded construction means the magnetic field extends beyond the component body — this matters for board layout because a nearby trace or another inductor can couple into the field. The trade-off is a higher self-resonant frequency: 27 MHz gives useful inductance well into the HF band, so this part works in DC-DC converters switching at 1–3 MHz where a shielded inductor would resonate lower. The Q factor is 30 at 1 MHz — a moderate Q for a power inductor, reflecting the balance between core loss and copper loss in the ferrite drum core. For a buck converter's output filter, this Q is high enough to keep ripple current under control without excessive ringing at the switching edge. ## 1812 footprint — a standard land pattern for power inductors The 1812 (4532 Metric) package is a common size for inductors in the 5–22 µH range. Surface-mount assembly with tape-and-reel packaging supports high-volume pick-and-place.","metaTitle":"Murata LQH43NH8R2J03L Inductor, 8.2 µH, 530 mA, 1812","metaDescription":"Murata LQH43NH8R2J03L drum core wirewound inductor, 8.2 µH, 530 mA, 216 mOhm DCR, AEC-Q200, 1812 SMD.
