These board level filters attenuate noise on the signal line at the frequency range of 10 MHz to 1000 MHz with maximum attenuation at 40 MHz to 400 MHz. The U shaped ferrite features a parallel first and second leg with a center leg surrounded by a grounding/shorting strap and a capacitor for each line. This unique design optimizes the filter performance by combining the elements into one low profile single piece filter. Each filter acts on two signal lines, but can be stacked as an array to allow performance over multiple lines. The BLF filter can withstand dielectric voltage of 1000 VAC for 60 seconds, thereby allowing placement of this filter at the optimal location, immediately behind the connector. This placement allows immunity protection from signal line interference as well as significant reduction of RFI emissions. The filter can be used in conjunction with unfiltered RJ jacks, ganged jacks, or with filtered modular jacks for additional protection. Dielectric Withstanding Voltag...
