B280LB0S-T

Overview

The B280LB0S-T is a surface mount bandpass filter manufactured by Knowles Dielectric Labs, designed for high-frequency signal conditioning applications. It operates at a center frequency of 28 GHz with a bandwidth of 2 GHz. The component features an insertion loss of 1.5 dB and utilizes low-loss, temperature-stable materials to ensure minimal performance variation across operating temperatures. Packaged in a 10-SMD, no-lead form factor suitable for automated assembly, this device supports reliable RF filtering in compact electronic systems requiring precise frequency selection.

Feature Summary

• Utilizes low-loss temperature stable materials for consistent performance
• Provides precise bandpass filtering at 28 GHz center frequency
• Compact surface mount design suitable for high-density PCB layouts

Applications

• Wireless communication systems requiring 28 GHz signal filtering
• High-frequency RF front-end modules
• Signal conditioning in microwave circuitry

Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging requirements. Ensure compatibility with existing SMD reflow profiles and handling procedures. Confirm that the 10-SMD package dimensions align with the target board layout. Validate supply chain availability through authorized distributors as stock levels may fluctuate.

Selection Notes

Select this component when a 28 GHz center frequency and 2 GHz bandwidth are required. Consider the 1.5 dB insertion loss specification for system power budget calculations. The temperature-stable material choice makes it suitable for environments where performance consistency is critical. Evaluate the 10-SMD footprint against available board space constraints.

Part Context

This part belongs to the B280 series of bandpass filters from Knowles Dielectric Labs. It shares core electrical characteristics with the standard B280LB0S variant but differs in packaging configuration. The series is characterized by its use of specialized dielectric materials for stability. It serves as a specialized solution for millimeter-wave applications within the broader RF filter portfolio.

Replacement Considerations

The B280LB0S is a confirmed substitute part number with identical electrical specifications. Verify that the packaging difference does not impact the assembly process. Ensure that any alternative components meet the same 28 GHz frequency and 2 GHz bandwidth requirements.
