4.7 µH Shielded Power Inductor for Automotive and Industrial DC-DC
The Murata LQH32PH4R7NNCL is a 4.7 µH shielded wirewound inductor from the LQH32 series, built on a ferrite core and qualified to AEC-Q200. The 1.6 A saturation current (Isat) provides headroom above the continuous rating, so the inductance holds up under transient load steps common in automotive ECU power stages.
AEC-Q200 Qualification and Temperature Grade
Rated AEC-Q200, this inductor is qualified for automotive-grade stress tests including thermal shock, vibration, and solder heat resistance.
Shielded Construction and Self-Resonant Frequency
The shielded ferrite core contains the magnetic flux, reducing radiated EMI to adjacent traces and components — a practical advantage when routing the inductor near sensitive analog or RF sections on the same PCB. Self-resonant frequency is 40 MHz, which sets the upper bound for effective inductive filtering. Below 40 MHz the part behaves as an inductor; above it, parasitic capacitance dominates and the impedance rolls off.
Package and Footprint: 1210 (3225 Metric)
The nonstandard case designation means the footprint matches the industry-standard 1210 land pattern — no special pad geometry required. Tape & Reel packaging (Cut Tape also available) supports automated pick-and-place assembly. Tolerance is ±30%, typical for power-grade inductors where the DC bias characteristic matters more than the absolute open-circuit value.
