4.7 µH wirewound inductor for DC-DC filtering and signal conditioning
The Murata LQH2MCN4R7M02L is a 4.7 µH unshielded wirewound inductor in the LQH2 series, built on a ferrite drum core. Rated for 300 mA continuous current with a maximum DC resistance of 1.04 Ohm, it is sized for low-to-moderate current paths in power supply filtering, DC-DC converter output stages, and signal conditioning circuits where the 0806 (2016 Metric) footprint fits the board layout. The self-resonant frequency of 60 MHz sets the upper bound for effective inductive behaviour; above this frequency the component transitions to capacitive impedance, so the operating frequency should stay well below 60 MHz to maintain the intended filtering or energy-storage function.
Unshielded construction and board placement considerations
This inductor is unshielded, meaning the magnetic field radiates from the core into the surrounding area. In a dense PCB layout, adjacent traces or components within the near-field zone may couple noise; a keep-out region or a ground plane beneath the part is advisable to contain the field and avoid crosstalk into sensitive analog or RF circuits.
Active lifecycle and sourcing posture
The part is supplied in Tape & Reel packaging, compatible with standard reel-fed assembly lines.
