This unshielded part is built on a ferrite core and targets filtering, DC/DC converter output, and general-purpose inductive loads where moderate inductance and current are needed. ## Current, resistance, and frequency limits Rated for 130 mA continuous current with a maximum DC resistance of 3.7 Ohm — at full rated current, the I²R loss is roughly 62.5 mW, which is manageable for the 1812 body but should be considered in dense layouts where self-heating adds to ambient temperature. The self-resonant frequency of 5.5 MHz marks the upper bound for effective inductive behaviour; above this frequency the part becomes capacitive. The Q factor is specified as 40 at 796 kHz, giving a reasonable efficiency figure for tuned or resonant circuits operating near that test frequency. Tolerance is ±5%, which is tighter than the typical ±10% or ±20% for many power inductors — useful for precision filtering or timing applications where inductance variation must be minimised. ## Temperature grade and board fit The unshielded construction means magnetic flux radiates from the core — keep sensitive traces or low-level analog circuits at least a few millimetres away to avoid coupling. It is supplied in tape-and-reel packaging and also available in cut-tape quantities for prototyping.","metaTitle":"Murata LQH43NN151J03L Inductor, 150 µH, 130 mA, 1812","metaDescription":"Murata LQH43NN151J03L drum core wirewound inductor, 150 µH ±5%, 130 mA, 3.7 Ohm DCR, 5.5 MHz SRF, -40°C to 105°C.
