Product Description

Mini-Circuits LFCN-490D+ Ceramic Low Pass Filter

The Mini-Circuits LFCN-490D+ is a ceramic low pass filter designed for efficient harmonic rejection and RF suppression. It offers excellent power handling capabilities (8.5W), a small size, and is constructed using LTCC (Low Temperature Co-Fired Ceramic) technology for temperature stability. This filter is ideal for applications in VHF/UHF transmitters and receivers, and for RF suppression on DC lines of PCBs, as well as anti-aliasing for A/D converters.
