B080KF4S-T

Overview

The B080KF4S-T is a surface-mount bandpass filter manufactured by Knowles Dielectric Labs. It operates at a center frequency of 8 GHz with an 80 MHz bandwidth. The component features a 50-ohm impedance and a maximum insertion loss of 2.5 dB. Designed for board mounting, it utilizes a 3-SMD, no-lead package configuration.

Feature Summary

• Surface-mount construction for automated assembly
• Bandpass filtering capability centered at 8 GHz
• Compact 3-SMD footprint design

Applications

• RF signal conditioning circuits
• Microwave communication systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with standard SMD reflow processes and validate impedance matching requirements within the target circuit design prior to integration.

Selection Notes

Select this component for applications requiring precise 8 GHz filtering with minimal insertion loss. Evaluate the 80 MHz bandwidth against system spectral requirements. Confirm that the 3-SMD package dimensions fit the available PCB real estate and thermal management constraints.

Part Context

This part belongs to the Knowles Dielectric Labs RF filter portfolio, specifically designed for high-frequency signal integrity. It serves as a passive component for frequency selection in microwave environments, distinct from active amplifiers or general-purpose capacitors.

Replacement Considerations

Consult official substitution lists for equivalent 8 GHz bandpass filters. Verify that alternative components match the 80 MHz bandwidth and 2.5 dB insertion loss specifications while maintaining the 3-SMD form factor.
