15 µH, 170 mA, AEC-Q200 — automotive-grade filtering
The Murata LQH32NZ150J23L is a drum core wirewound inductor rated for 15 µH ±5% at 1 MHz test frequency, carrying 170 mA DC with a maximum DC resistance of 2.2 Ω. The 1210 (3225 metric) footprint and 2.20 mm seated height fit standard pick-and-place assembly; the unshielded ferrite core is suited for filtering and decoupling where magnetic coupling between adjacent inductors is managed by layout spacing.
Operating envelope and self-resonant behaviour
Q factor is 35 at 1 MHz, typical for a ferrite-core drum inductor at this inductance value; the Q and SRF together define the insertion loss in a pi-filter stage.
