The CFUK455KA2XR0 is a ceramic filter manufactured by Murata Electronics North America. Ceramic filters are passive electronic components used to selectively pass or reject signals within a specific frequency range. They are commonly employed in communication and signal processing applications to remove unwanted noise and interference.

Applications

• Radio Receivers: Used in radio receivers to filter out unwanted signals and improve selectivity.
• Communication Systems: Employed in communication systems, such as cellular phones and wireless devices, to filter out noise and interference.
• Signal Processing: Utilized in signal processing applications to selectively pass or reject signals within a specific frequency range.
• Audio Equipment: Found in audio equipment, such as audio amplifiers and mixers, to filter out unwanted noise and distortion.

Features

• Narrow Bandwidth: Offers a narrow bandwidth for selective filtering of signals.
• High Attenuation: Provides high attenuation of unwanted signals outside the passband.
• Compact Size: Available in a compact size for space-constrained applications.
• Stable Performance: Offers stable performance over a wide range of operating conditions.
• RoHS Compliant: Complies with the Restriction of Hazardous Substances (RoHS) directive.

Benefits

• Improved Signal Quality: Enhances signal quality by filtering out unwanted noise and interference.
• Enhanced Selectivity: Improves the selectivity of radio receivers and communication systems.
• Space-Saving Design: Allows for compact designs, minimizing the overall size of electronic devices.
• Reliable Performance: Offers reliable performance in various operating conditions.
• Environmentally Friendly: Complies with environmental regulations.

Additional Details

The CFUK455KA2XR0 operates at a specific center frequency, typically in the kilohertz (kHz) or megahertz (MHz) range. The filter's bandwidth, attenuation, and insertion loss are critical parameters that determine its performance. It is typically packaged in a leaded or surface-mount package. Consult the product datasheet for detailed technical specifications, pin assignments, and application guidelines. The '455K' likely signifies a center frequency near 455 kHz, but this must be verified with the datasheet.
