( Brand: Murata ), ( Manufacturer Part Number: CFJ455K12 ), ( Part Type: Filter Radio )
The CFJ455K12 Murata ceramic filter is a high-quality component designed specifically for use in radio frequency (RF) applications. This 2.9 kHz ceramic filter is a critical component in radio systems, as it helps to filter out unwanted frequencies and improve the overall signal quality.
The CFJ455K12 is a surface mount device (SMD), which means it can be easily integrated into circuit boards with minimal space requirements. The ceramic material used in its construction provides excellent electrical properties, including low insertion loss, high Q-factor, and high stability over temperature.
The filter has a center frequency of 2.9 kHz, which makes it suitable for use in narrowband applications such as AM radio, FM broadcast, and some types of wireless communication. The filter's 3 dB bandwidth is 300 Hz, which ensures that only the desired frequency range is passed through, while unwanted frequencies are effectively blocked.
The CFJ455K12 is a dual-terminal filter, with inputs and outputs on opposite sides of the device. It has a maximum power rating of 1 watt, which ensures that it can handle moderate power levels without overheating or degrading in performance.
The filter is RoHS compliant, which means it does not contain any harmful substances such as lead, cadmium, mercury, or hexavalent chromium. It is also halogen free, which makes it suitable for use in environments where flame retardant materials are required.
In summary, the CFJ455K12 Murata ceramic filter is a high-quality, surface mount device that is ideal for use in RF applications requiring narrowband filtering and excellent electrical performance. Its low insertion loss, high Q-factor, and high stability over temperature make it a reliable choice for applications in the radio and wireless communication industries.
