F1199AA20 is a single-phase RFI filter designed for general-purpose electromagnetic interference suppression in industrial and commercial applications. This 40A-rated filter features quick-connect (QC) termination on both line and load sides, optimized for common-mode noise attenuation across a wide frequency range. The filter delivers minimum insertion loss performance of 10 dB at 0.15 MHz, 20 dB at 0.30 MHz, 28 dB at 1.0 MHz, 35 dB at 5.0 MHz, 38 dB at 10 MHz, and 40 dB at 30 MHz in a 50 mm circuit configuration. With a rated voltage of 250VAC maximum at 50/60 Hz, maximum leakage current of 0.25 mA at 115VAC 60Hz, and hi-pot test ratings of 1500VAC line-to-ground and 1450VAC line-to-line, this filter provides robust protection against RFI in power distribution systems. The F1199AA20 is ideal for equipment requiring reliable noise filtering with compact dimensions and convenient quick-connect terminals.
