F455K000S011

Overview

The F455K000S011 is a Surface Acoustic Wave (SAW) bandpass filter manufactured by Abracon LLC. It operates at a center frequency of 455 kHz with a bandwidth of 4.5 kHz. The device features a typical insertion loss of 6.0 dB and is housed in a compact 3-SMD surface-mount package.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise signal filtering
• Designed as a bandpass filter for specific frequency selection
• Compact three-terminal surface-mount construction

Applications

• Intermediate frequency stages in radio receivers
• Signal processing circuits requiring 455 kHz filtering
• Communication equipment frontend modules

Procurement Notes

Verify the exact datasheet specifications against the manufacturer's official documentation before integration. Confirm that the 3-SMD footprint matches your PCB layout requirements. Ensure compatibility with your assembly process regarding thermal profiles and soldering standards for SAW devices.

Selection Notes

Select this component when a narrow bandpass characteristic centered at 455 kHz is required. The 4.5 kHz bandwidth defines the selectivity, while the 6.0 dB insertion loss impacts signal strength. Evaluate the SMD package size constraints against available board space.

Part Context

This part belongs to Abracon's RF filter portfolio, which includes various SAW and ceramic filters. The company provides frequency control and timing solutions alongside these passive components. The F455K series targets applications needing stable intermediate frequency performance.

Replacement Considerations

Cross-reference with other 455 kHz SAW filters from different manufacturers if supply is constrained. Verify that substitute parts maintain identical bandwidth, insertion loss, and physical dimensions to ensure circuit compatibility without redesign.
