Active part, 15 µH shielded inductor for DC-DC and signal filtering
The Murata LQH2MPN150MGRL is a 15 µH shielded wirewound inductor in the LQH2 series, rated for 340 mA continuous current with a saturation current of 490 mA. The 150 mA headroom between rated and saturation means the core holds inductance well into overload without abrupt roll-off — useful for circuits where the load current spikes above the DC average. Maximum DC resistance is 2.04 Ω, producing a copper loss of roughly 0.23 W at full rated current. Self-resonant frequency is 25 MHz. Below that frequency the part behaves as an inductor; above it the impedance becomes capacitive. For a buck converter switching at 2–3 MHz, the SRF provides margin; for a 10 MHz switching regulator, the margin narrows and the effective inductance drops near the SRF knee. The ferrite core and full magnetic shielding reduce radiated EMI to adjacent traces — a consideration in mixed-signal boards where the inductor sits near an ADC or RF front-end. Tolerance is ±20%, which is typical for power-grade ferrite inductors; the actual inductance under DC bias may shift more than the tolerance band, so the saturation current (490 mA) is the tighter design constraint for current-limited rails.
Package and footprint for 0806 assembly
The low profile fits under a 1.2 mm board-to-board clearance or behind a low-profile shield can. Tape-and-reel packaging supports automated pick-and-place; the reel quantity is confirmed at RFQ.
