820 nH wirewound inductor for RF and decoupling
The Murata LQH31MNR82K03L is a drum core wirewound inductor in the LQH31 series, offering 820 nH inductance with ±10% tolerance. It is rated for 185 mA continuous current and has a DC resistance of 730 mOhm, which sets the self-heating limit at that current. With a self-resonant frequency of 120 MHz and a Q factor of 30 at 25 MHz, this inductor is suited for RF circuits, impedance matching, and filtering in the lower VHF band. The unshielded construction means it should be placed away from sensitive traces or shielded inductors in dense layouts.
Package and storage considerations
Supplied on tape and reel, the reels should be stored in a dry environment — the unshielded drum core is not moisture-sensitive per MSL, but the reel packaging can absorb humidity over long storage.
