82 µH shielded wirewound for automotive and industrial DC-DC
The Murata LQH2MPZ820MGRL is a drum core wirewound inductor in the LQH2 series, delivering 82 µH ±20% in a shielded 0806 (2016 Metric) package. Rated at 150 mA with a saturation current floor of 210 mA, it is built for power rail filtering and DC-DC converter output stages where inductance stability under bias matters. AEC-Q200 qualification means this part is characterized for automotive-grade stress profiles — thermal shock, vibration, and humidity bias per the passive component qualification standard. The ferrite core and shielded construction keep magnetic flux contained, reducing coupling into adjacent traces on a densely populated board.
Parametric fit: DCR, current, and self-resonant frequency
DC resistance is 8.76 Ohm max — the dominant loss term at 150 mA. The I²R loss at full rated current is roughly 0.2 W, which the 0806 body must dissipate through the board copper. The self-resonant frequency of 5 MHz sets the usable band: above this, the inductor behaves capacitively, so it suits switching converters switching below 2-3 MHz. Saturation current is specified at 210 mA, a 40 % headroom above the rated current. This margin means the inductance holds within ±10 % of nominal at the 150 mA operating point — critical for maintaining ripple current limits in a buck regulator's output filter.
Active lifecycle and sourcing posture
It is available through independent distribution channels, quoted to order against BOM quantities. The 0806 footprint and tape-and-reel packaging align with standard pick-and-place assembly.
