22 µH in a 1008 shield — sizing the filter choke for a 95 mA rail
The Murata LQH2HNH220J03L is a 22 µH shielded wirewound inductor in the 1008 (2520 metric) package, rated for 95 mA continuous current with a DC resistance of 2.75 Ω. The 95 mA rating sets the ceiling for the DC bias current in a buck converter output filter or a low-power supply rail — the inductor saturates or overheats above this, so the load current plus ripple current peak must stay under it.
AEC-Q200 and the 125°C ceiling — where this part lives in the vehicle
AEC-Q200 qualification means the LQH2HNH220J03L passed the automotive-grade stress tests: thermal shock, mechanical shock, vibration, and solder heat resistance per the passive-component qualification standard.
Shielding and self-resonant frequency — keeping noise off the adjacent trace
The shielded construction contains the magnetic flux within the core — critical when the inductor sits next to a sensitive analog front-end or a crystal oscillator on a dense automotive ECU board. Self-resonant frequency is 21 MHz — the inductor behaves inductively only below that frequency. For a 2.2 MHz switching regulator, the 21 MHz SRF gives about 10× margin before the impedance turns capacitive, which is safe for the fundamental but check the harmonic content of the switching waveform.
Sourcing posture for the BOM line
The 1008 package and ±5% tolerance match the standard LQH2 series footprint, so a reel quantity can be quoted for the BOM line.
