BFCN-2555+

Overview

The BFCN-2555+ is a surface-mount LTCC bandpass filter designed for the 2.50 to 2.61 GHz frequency range. It features a center frequency of 2555 MHz with a bandwidth of 110 MHz and operates at a nominal impedance of 50 Ohms. The component utilizes a 1206 package style (FV1206-1) to ensure high repeatability and miniature size. Key electrical characteristics include an insertion loss ranging from 3.78 dB, making it suitable for signal conditioning in RF circuits requiring precise frequency selection.

Feature Summary

• Constructed using Low-Temperature Co-fired Ceramic (LTCC) technology for high performance and reliability
• Features wrap-around termination design to minimize parasitic effects
• Compact 1206 footprint allows for high circuit board layout density

Applications

• RF signal conditioning modules
• Wireless communication systems operating in the 2.5 GHz band
• Frequency selective filtering in receiver front-ends

Procurement Notes

Verify the specific datasheet revision and electrical parameter tolerances against the manufacturer's official documentation before integration. Confirm that the 1206 package dimensions and pin configuration match the target PCB layout requirements. Ensure compliance with relevant RoHS directives if required by the end application specifications.

Selection Notes

Select this component when a compact, high-repeatability bandpass filter is needed for the 2.5–2.61 GHz range. The LTCC construction offers advantages over traditional ceramic filters regarding size and parasitic minimization. Consider the 3.78 dB insertion loss specification when designing for low-noise applications or when signal attenuation budgets are tight.

Part Context

This part belongs to Mini-Circuits' BFCN series of LTCC bandpass filters. These components are engineered to provide stable frequency response in a small form factor. The series is commonly used in modern RF designs where space constraints and consistent manufacturing quality are critical factors for system performance.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified alternatives. Generic equivalents may not replicate the specific LTCC layer construction or wrap-around termination characteristics required for optimal performance in this frequency band.
