Product details

2.4 mH wirewound in the 1812 footprint

The Murata LQH43NN242K03L is a drum-core wirewound inductor from the LQH43 series, delivering 2.4 mH ±10% in a standard 1812 (4532 Metric) surface-mount package. Rated for 25 mA DC with a maximum DC resistance of 53 Ohm, this part is sized for low-current filtering and decoupling roles where inductance stability over temperature matters more than current handling.

Parametric fit for signal and bias lines

Unshielded construction means the stray field couples into adjacent traces — keep a clearance of at least one package width to sensitive signal routing on the same layer.

Active production, sourced to order

Supplied on tape and reel (cut tape available), this is a standard 1812 footprint that reflows on a typical lead-free profile without special handling.

Frequently asked questions

What is the self-resonant frequency of this inductor?

The LQH43NN242K03L has a self-resonant frequency of 1.2 MHz, which defines the upper frequency limit for effective inductive impedance.
