Rated for 45 mA DC current, this part suits low-power filtering, decoupling, and bias circuits where the DC resistance of 11 Ohm is acceptable relative to the load current. ## Self-resonant frequency and operating temperature With a self-resonant frequency of 7.5 MHz, the inductor maintains its inductive impedance up to that point; above it, parasitic capacitance dominates and the part behaves capacitively. The ferrite core and unshielded construction keep the part cost-effective, but the lack of magnetic shielding means adjacent traces or components may pick up stray flux — board layout should account for this.","metaTitle":"Murata LQH31MN820J03L 82 µH Inductor, 45 mA, 1206","metaDescription":"Murata LQH31MN820J03L drum core wirewound inductor, 82 µH, ±5%, 45 mA, 11 Ohm DCR, 1206 package.
