The 100 MHz self-resonant frequency keeps the impedance inductive well above the switching ripple frequencies of common 500 kHz to 2 MHz buck converters. Below the SRF the choke presents a clean inductive impedance; above it the parasitic capacitance dominates and the part stops filtering. Unshielded construction means the magnetic field extends beyond the package body. On a dense PCB, keep a clearance of at least one body width to adjacent inductors or sensitive analog traces to avoid cross-coupling. ## Active production, standard sourcing The ±20% tolerance is typical for power-grade inductors where the DC-DC loop compensates for the inductance spread.","metaTitle":"Murata LQH32CN1R0M33L Inductor, 1 µH, 1 A, Unshielded","metaDescription":"Murata LQH32CN1R0M33L drum core wirewound inductor, 1 µH ±20%, 1 A rated, 78 mOhm DCR, 100 MHz SRF.
