Active AEC-Q200 shielded inductor for automotive power rails
The LQH2HPZ1R0MDRL is an active-production shielded wirewound inductor from Murata's LQH2 series, qualified to AEC-Q200 for automotive-grade reliability. Its 1 µH ±20% inductance with a 960 mA rated current and 1.37 A saturation current means the part has roughly 40% headroom above the rated current before the inductance drops — a useful margin for DC-DC converter ripple currents that spike above the average load.
DC loss and thermal budget at rated load
With a maximum DC resistance of 288 mOhm, the I²R loss at 960 mA is about 265 mW. The 100 MHz self-resonant frequency sits well above the 1–4 MHz switching frequencies typical of automotive buck converters, so the inductor behaves as a pure inductor across the converter's operating band without capacitive coupling at the switching edge.
Package and board-fit for space-constrained ECUs
The shielded construction reduces radiated EMI into adjacent traces, which matters when the inductor sits next to a CAN transceiver or a sensitive sensor front-end on the same layer.
