6.8 µH shielded power inductor for automotive and industrial DC-DC filtering
The Murata LQH32PH6R8NN0L is a 6.8 µH shielded wirewound inductor in the LQH32 series, rated for 850 mA continuous current with a maximum DC resistance of 288 mOhm. The shield construction contains the magnetic field, reducing radiated EMI that could couple into nearby signal traces on a dense PCB.
850 mA current rating and 288 mOhm DCR — what they mean for your power rail
The 850 mA current rating is the same as the saturation current (Isat 850 mA), so the inductor maintains its inductance up to the full rated current without a hard roll-off. This is important for DC-DC converter output stages where the inductor sees the full load current plus ripple — the part will not saturate prematurely at peak load. With 288 mOhm max DCR, the I²R conduction loss at 850 mA is about 208 mW. The self-resonant frequency of 40 MHz is well above typical switching frequencies for automotive and industrial buck converters (usually 400 kHz to 2.2 MHz), so the inductor behaves as a pure inductive element in that band without capacitive coupling.
1210 footprint and hand-solderability
The nonstandard case designation means the pad layout follows the 1210 footprint — the two terminals are on the short sides, so the inductor sits across the trace direction. It is hand-solderable with a fine-tip iron, though the shield can wick heat away from the joint; pre-tin the pad and use a hot-air station if you are doing more than a few.
