Shielded 470 nH inductor for DC-DC input/output filtering
The Murata LQH2HPNR47MDRL is a shielded drum-core wirewound inductor in the LQH2 series, rated 470 nH ±20% with a continuous current rating of 1.25 A and a saturation current of 1.67 A.
Self-resonant frequency and board-fit parameters
A self-resonant frequency of 120 MHz means the inductor behaves inductively well into the VHF band, making it suitable for filtering in switching converters switching at a few MHz or for RF bias-tee applications where the inductor must not self-resonate within the signal bandwidth. Inductance is tested at 1 MHz, which is the standard reference frequency for this value range; the ±20% tolerance is typical for power-grade inductors where the DC bias characteristic matters more than the absolute L value.
