Product details

Active 15 µH wirewound — LQH43 series

The Murata LQH43CN150K03L is an active-production, unshielded drum-core wirewound inductor in the LQH43 series, rated 15 µH ±10% at 1 MHz test frequency. The self-resonant frequency of 20 MHz sets the upper bound for inductive behaviour; above this frequency the impedance turns capacitive, which matters when the inductor is used in a DC-DC output filter or a bias-tee network.

Unshielded construction and board-fit note

Unshielded magnetic circuit means the flux field extends beyond the component body — adjacent traces carrying high-frequency signals or sensitive analog lines should be kept at least one part-width away to avoid unwanted coupling. The ferrite core material supports the inductance stability across the operating temperature range.

Frequently asked questions

What is the closest pin-compatible alternative to LQH43CN150K03L in the LQH43 family?

The LQH43 series includes multiple inductance values in the same 1812 footprint — e.g., 10 µH, 22 µH, or 33 µH variants — but no official cross-reference or second-source is published. If the BOM calls for 15 µH at 570 mA, the LQH43CN150K03L is the Murata order code that matches that inductance and current rating.

What compliance documentation does Murata provide for LQH43CN150K03L?

Murata Electronics provides RoHS and REACH compliance data for the LQH43 series inductors. No UL or IEC certification is listed in the product record; the part is typically used in general-purpose industrial and consumer electronics where component-level safety listings are not required.
