The 660 mOhm max DCR sets the conduction loss — at full rated current the I²R loss is about 0.38 W, which the 1212 (3030 Metric) package dissipates through the board copper. The 440 mA saturation current (Isat) is the hard ceiling: above it the inductance drops off, so a DC-DC converter drawing 500 mA steady-state needs a higher Isat part. AEC-Q200 qualified, so it passes the automotive-grade stress tests — thermal shock, moisture resistance, and mechanical shock per the standard. ## Package and rework reality Shielded construction means the magnetic field stays mostly inside the core — adjacent traces or a nearby inductor on the same rail won't couple parasitically. For a multi-phase buck converter, this lets you place the inductors closer together without cross-talk.","metaTitle":"Murata LQH3NPH330MMEL 33 µH Shielded Inductor, 760 mA","metaDescription":"Murata LQH3NPH330MMEL drum core wirewound inductor, 33 µH ±20%, 760 mA, shielded, AEC-Q200.

If your load draws 500 mA steady-state, the effective inductance falls below 23 µH — the ripple current in a buck converter increases, and the output voltage ripple rises. Choose a higher-current-rated part for that margin."},{"question":"What is the self-resonant frequency of this inductor?","answer":"The self-resonant frequency is 8 MHz.
