82 µH at 170 mA — filtering or decoupling fit
The LQH43MN820K03L is a Murata drum core wirewound inductor rated at 82 µH ±10% with a continuous current of 170 mA. The 2.2 Ohm max DCR means the DC voltage drop across the part at full rated current is about 0.37 V — a factor to budget in low-voltage rails where every millivolt of headroom matters. Unshielded construction and a ferrite core keep the self-resonant frequency at 7.5 MHz, so this choke is a natural fit for low-frequency filtering or DC bias decoupling below that band. The Q factor of 35 at 1 MHz gives a reasonable selectivity for tuned circuits if the application can tolerate the unshielded field.
Surface-mount footprint and temperature envelope
The ferrite core material and wirewound construction deliver stable inductance over the temperature band, though the unshielded design means the inductor radiates a magnetic field — keep sensitive traces or low-level analog circuits at least a few mm away.
