The 335 mA current rating and 1.19 Ohm max DCR define the DC loss budget — at full rated current the self-heating from I²R is roughly 134 mW, which stays within the 0806 package's thermal limits in still air. The self-resonant frequency of 90 MHz sets the upper bound for effective filtering — above that the inductor behaves capacitively. For a buck converter switching at 2 MHz, the impedance at the switching frequency is well below resonance, so the inductor delivers its nominal inductance with low parasitic loss. The inductance tolerance is ±20%, which is typical for power-grade ferrite-core inductors — the actual value at the operating current and temperature will shift within this band due to DC bias and core heating. ## Board-fit and sourcing posture The part is unshielded, so magnetic coupling to nearby traces or components should be considered in layout; a keep-out zone under the part on inner layers is not required. No pin-compatible direct replacement is listed, but the LQH2 series includes other inductance values in the same footprint if a design change is needed.","metaTitle":"Murata LQH2MCN4R7M52L 4.7 µH Unshielded Wirewound Inductor","metaDescription":"Murata LQH2MCN4R7M52L drum core wirewound inductor, 4.7 µH ±20%, 335 mA, 1.19 Ohm DCR, 0806 package.
