That inductance value and SRF combination places it in the low-frequency filtering and energy storage band — think DC-DC converter output chokes, EMI suppression below 3 MHz, or decoupling a supply rail that carries ripple at switching frequencies in the hundreds of kilohertz. If your load draws above 80 mA, the core saturates and inductance falls off — this part is sized for signal-level or low-power auxiliary rails, not a main power bus. ## 1812 footprint and unshielded construction — board-fit considerations The unshielded drum-core construction means the magnetic field extends beyond the package — keep sensitive traces or adjacent magnetics at least one part-width away to avoid coupling. Surface-mount assembly on standard FR-4 is straightforward; the 1812 footprint is common across multiple vendors, so the pad layout is interchangeable with other 1812 wirewound inductors. The Q factor is 40 at 796 kHz, which is typical for a ferrite-core part at this inductance — adequate for resonant tank circuits or tuned filters in that frequency range.","metaTitle":"Murata LQH43MN471K03L Inductor, 470 µH, 80 mA, 1812","metaDescription":"Murata LQH43MN471K03L drum core wirewound inductor, 470 µH ±10%, 80 mA rated current, 11.8 Ohm DCR, 1812 SMD.
