## Description

The Murata CFS455C is a high-performance ceramic filter designed for use in various radio equipment. It operates at a nominal center frequency of 455 kHz with a specified 3dB bandwidth of 5.5 kHz and a 6dB bandwidth of 15 kHz. The filter offers a maximum insertion loss of 4 dB and a minimum attenuation of 70 dB at 455±100kHz.

This filter is constructed using piezoelectric elements in a ladder form, providing high selectivity and stable operation across a wide temperature range of -20°C to 80°C. The CFS455C is suitable for intermediate-frequency filters in high-class receivers and SSB communications equipment. It is designed for through-hole mounting and has physical dimensions of 29 x 7.5 x 10.5 mm.

Key electrical characteristics include an input/output impedance of 1500 Ohms and spurious attenuation of 50 dB minimum at 0.1±1MHz. The operating temperature range is -20°C to 80°C, with a storage temperature range of -40°C to 85°C.
