It's the sort of part you find on a power rail filter or a DC-DC converter output — the 450 mA current rating and 260 mOhm max DCR tell you it's sized for moderate loads, not high-current switching. The unshielded construction means the field radiates a bit, so keep sensitive traces a few mm away on the board. Self-resonant frequency sits at 43 MHz, so it behaves as an inductor well into the tens of MHz — fine for a buck converter switching at a few MHz or a filter on a 2.4 GHz supply rail where the SRF is comfortably above the noise band. The 1210 (3225 metric) footprint is a common size, easy to hand-place or reflow. ## Temperature range and board-fit notes The ferrite core material holds its inductance reasonably flat across that range, though the DCR will drift with temperature — expect about 0.4% per °C on the copper winding. The part is unshielded, so if you're stacking boards or placing it near a wireless antenna, budget for some magnetic coupling. The nonstandard case designation just means it's not a generic chip shape; the pad layout matches the LQH32 series datasheet. Tape-and-reel packaging is standard for pick-and-place.","metaTitle":"Murata LQH32DN4R7M23L Inductor, 4.7 µH, 450 mA","metaDescription":"Murata LQH32DN4R7M23L drum core wirewound inductor, 4.7 µH ±20%, 450 mA, 260 mOhm DCR, 1210 package.
