The 2.5 Ohm max DCR sets the DC loss budget — at full rated current the self-heating is roughly 64 mW, which is within the 85°C ambient ceiling for most board-level power filters. The self-resonant frequency of 6.8 MHz means the inductor's impedance peaks near that point and drops above it — useful for filtering switching noise from a buck converter running at a few hundred kHz, but not for RF tank circuits above 10 MHz. ## 1812 footprint, unshielded — layout and coupling Being unshielded, the magnetic field extends beyond the core — adjacent traces carrying sensitive analog signals should be kept at least one part-width away to avoid coupling. The ferrite core material gives a Q factor of 40 at 796 kHz, indicating moderate energy efficiency in the low-MHz range. The inductance is tested at 1 MHz, which is the standard reference frequency for this value range. ## Active production, industrial temperature range Surface-mount packaging options include Tape & Reel and Cut Tape, compatible with standard pick-and-place assembly.","metaTitle":"Murata LQH43MN101K03L 100 µH Unshielded Inductor, 160 mA","metaDescription":"Murata LQH43MN101K03L drum core wirewound inductor, 100 µH ±10%, 160 mA, 2.5 Ohm DCR, 1812 SMD.
