The 216 mOhm max DCR sets the I²R loss at full load to about 216 mW — within the thermal budget of the 1210 footprint for most automotive cabin and industrial applications. It is suitable for engine control units, transmission controllers, and body electronics where the ambient temperature stays within -40°C to 85°C. ## Shielded construction and frequency ceiling The ferrite core and shielded winding reduce magnetic flux leakage, which keeps EMI coupling into adjacent traces below 5% of the unshielded case in a typical 4-layer PCB stack-up. The 40 MHz self-resonant frequency means the inductor behaves inductively up to about 10 MHz — above that the parasitic capacitance dominates and the impedance rolls off. Inductance is tested at 1 MHz, which is the standard test frequency for the 4.7 µH value. The ±30% tolerance is wide — typical for power-grade ferrite inductors — so the DC-DC converter loop compensation must accommodate the full inductance spread from 3.3 µH to 6.1 µH. ## Active lifecycle and sourcing posture The 1210 (3225 Metric) footprint is industry-standard and pick-and-place compatible. The tape-and-reel packaging (cut tape also available) supports both prototype builds and volume production without a packaging change.","metaTitle":"Murata LQH32PH4R7NN0L Shielded Power Inductor, 4.7 µH, 1 A","metaDescription":"Murata LQH32PH4R7NN0L drum core wirewound inductor, 4.7 µH ±30%, 1 A rated, 216 mOhm DCR, shielded, AEC-Q200.
