560 nH in a 1812 body — what the ratings mean on the bench
The LQH43CNR56M33L is a drum-core wirewound inductor from Murata's LQH43 series, packing 560 nH ±20% into an 1812 (4532 Metric) surface-mount package. Rated for 2.95 A continuous with a maximum DC resistance of 30 mOhm — the DCR is the number that governs copper loss and self-heating at that current, not just the inductance value. Self-resonant frequency sits at 160 MHz, so the inductor looks inductive well into the VHF band — useful for filtering in switching converters and RF bias-tee circuits where the SRF needs to stay above the operating frequency.
Unshielded construction means the magnetic field extends outside the core — keep sensitive traces or other magnetics at least one body width away to avoid coupling.
Sourcing and lifecycle posture
Marked as Active by Murata — this is a current-production part, not a last-time-buy or NRND situation.
