Product details

220 µH wirewound for power-line filtering

The Murata LQH43NH221J03L is a 220 µH drum-core wirewound inductor in the LQH43 series, rated for 100 mA continuous current with a maximum DC resistance of 4.56 Ohm. Its self-resonant frequency of 4.5 MHz means this inductor stays inductive well into the low-MHz switching range, making it a fit for DC-DC converter output filters and EMI suppression on power rails where the ripple frequency sits below 2–3 MHz.

The base product number LQH43NH covers the full inductance range in this series; the suffix 221J03L encodes the 220 µH value, ±5% tolerance, and packaging variant.

Frequently asked questions

What is the DC resistance of LQH43NH221J03L and why does it matter?

The maximum DCR is 4.56 Ohm. At 100 mA rated current, this produces about 45.6 mW of self-heating — negligible for the 1812 body, but the voltage drop across the winding (0.456 V at full current) must be accounted for in the power rail budget.

What compliance documentation does Murata provide for LQH43NH221J03L?

As an AEC-Q200 qualified component, Murata provides a PPAP (Production Part Approval Process) package, RoHS/REACH compliance declarations, and a full reliability test report upon request through the supply chain.
