2.2 µH shielded power inductor at 990 mA — the Last Buy window
Murata has placed the LQH2HPN2R2MJRL into Last Buy status — the manufacturer no longer accepts new orders for ongoing production. This is the final procurement window for this specific inductance and current rating in the LQH2 series. The part is a shielded drum-core wirewound inductor rated at 2.2 µH with a saturation current floor of 1.7 A and a continuous current rating of 990 mA. The 110.4 mOhm max DCR sets the I²R conduction loss in the power rail — at full rated current the self-heating adds roughly 108 mW, well within the ferrite core's thermal budget at 105 °C ambient. The 50 MHz self-resonant frequency means the inductive impedance holds up well into the HF switching range — suitable for DC-DC converter applications switching at 1-2 MHz where the SRF stays a decade above the fundamental.
1008 footprint and board integration
The ferrite core and shielded construction reduce magnetic flux leakage into adjacent traces — useful when routing near sensitive analog or RF sections on a mixed-signal board. The inductance is tested at 1 MHz with a ±20 % tolerance — typical for power-grade ferrite inductors where the DC bias characteristic matters more than the no-load value.
Sourcing posture for a Last Buy part
Because Murata has flagged this as Last Buy, new-old-stock and surplus inventory are the remaining supply channels. Availability is lot-specific; quantities and date codes are confirmed at RFQ. The base product number LQH2HPN covers the series — buyers specifying this exact 2.2 µH ±20 % variant should verify the full suffix against their BOM before committing.
