Rated for 730 mA continuous current with a saturation current floor of 750 mA, the core saturates only after the rated current is exceeded — a design choice that keeps the inductance stable across the full operating range for a buck converter drawing 600 mA steady-state. The 540 mOhm maximum DCR sets the conduction loss at full load to roughly 0.29 W (I²R) — the self-heating stays within the ferrite core's thermal limits, but the PCB copper plane under the 1008 footprint should have a solid thermal via to the ground layer if ambient exceeds 85°C. ## Shielding and Self-Resonant Frequency for EMI Containment The shielded ferrite construction contains the magnetic flux within the core body, reducing radiated emissions from the inductor into adjacent traces or the enclosure — a requirement for CISPR 25 Class 5 conducted emissions in automotive ECU layouts. Self-resonant frequency is 45 MHz, well above the 2–3 MHz switching frequency typical of automotive buck converters; the inductor behaves as a pure inductive element in that band, with the parasitic capacitance only becoming significant above 20 MHz where the impedance slope flattens. ## Procurement and Sourcing for the BOM Line The base product number LQH2HPZ covers the full inductance range in this series — a BOM change to a different value within the family shares the same 1008 footprint and shielding construction, simplifying qualification for alternate values.","metaTitle":"Murata LQH2HPZ3R3MDRL 3.3µH Shielded Inductor, 730mA","metaDescription":"Murata LQH2HPZ3R3MDRL 3.3µH shielded wirewound inductor, 730mA, 540mOhm DCR, AEC-Q200 qualified, -40°C to +105°C.
