Surface-Mountable RFI Filters Eliminate Noise On Signal Lines

Designed to eliminate noise on signal lines in telecomm applications, the BLF Series of surface-mountable RFI filters are available in either an 82 pF or 820 pF version. The U-shaped ferrites have a parallel first and second leg surrounded by a grounding strap and a capacitor for each line, optimizing filter performance by combining the elements into one low-profile, single-piece device. Each SMT filter acts on two signal lines, but can be stacked as an array to allow performance over multiple lines.
