6.8 µH wirewound inductor — core parametrics and AC performance
The Murata LQH43NN6R8K03L is a drum-core, ferrite-core wirewound inductor in the LQH43 series, unshielded, with an inductance of 6.8 µH at 1 MHz test frequency and ±10% tolerance. Rated for 450 mA continuous current with a maximum DC resistance of 500 mΩ — the DCR sets the I²R heating floor at full load, so derate for ambient temperature above 85°C. Self-resonant frequency is 31 MHz, and the Q factor is 30 at 1 MHz, giving a usable inductive region up to roughly 10 MHz before parasitic capacitance dominates.
1812 SMD footprint and temperature envelope
Operating temperature range is -40°C to +105°C, suitable for industrial and automotive cabin environments but not for under-hood exposure above 105°C. Supplied on tape and reel (cut tape available), making it compatible with automated assembly lines.
