2.7 µH wirewound for automotive power and signal filtering
The Murata LQH32NH2R7J23L is a drum core wirewound inductor in the LQH32 series, rated at 2.7 µH with a ±5% tolerance. It carries a continuous current rating of 495 mA and a maximum DC resistance of 180 mOhm, making it a fit for DC-DC converter output filters and power supply decoupling in automotive electronics.
Self-resonant frequency and Q factor for RF and filter circuits
With a self-resonant frequency of 70 MHz and a Q factor of 20 at 1 MHz, this inductor maintains its inductive impedance well into the VHF band. The Q value at the test frequency gives a measure of AC loss — useful when estimating filter insertion loss or tank circuit performance in low-power RF stages. The 180 mOhm DCR sets the I²R heating floor at rated current: at 495 mA, the self-heating is roughly 44 mW, which is negligible in most PCB layouts but should be factored into dense power-stage designs.
1210 footprint and unshielded construction
The unshielded drum core construction means the magnetic field extends beyond the package — keep sensitive traces or adjacent magnetics at least one part-width away to avoid coupling. Available on tape and reel or cut tape, it suits both prototyping and volume pick-and-place.
