Murata BL01 BL02 BL03 Series EMI Leaded Filters Datasheet
The BL01, BL02 and BL03 series are Murata leaded EMI filters designed for high‑density printed‑circuit‑board applications such as micro‑computers, switching regulators, digital control equipment and automotive radios. Both axial and radial lead versions are offered, with single‑bead and double‑bead constructions for enhanced noise suppression.
The document provides a complete part‑numbering system, electrical characteristics (permeability, saturation flux, coercive force, Curie point, temperature coefficient, loss factor, resistivity), mechanical dimensions, and packaging options (tape, reel, bulk, ammo). All parts are available through authorized Murata Electronics distributors.
