BFCN-2500+

Overview

The BFCN-2500+ is an LTCC bandpass filter designed for surface mount applications. It operates within a frequency range of 2100 MHz to 2900 MHz, providing a bandwidth of 800 MHz. The component features a 50 Ohm impedance and utilizes SMD/SMT termination types in a 1206 package (Case Style FV1206-4). It exhibits a typical insertion loss of 2 dB and offers 20 dB rejection at the upper and lower stopband edges. The device supports a minimum operating temperature of -55°C and a maximum of +100°C.

Feature Summary

• Constructed using multilayer ceramic technology for high repeatability and ruggedness in tough environments
• Wrap-around terminations minimize performance variations caused by parasitics
• Provides low insertion loss and effective rejection at band-reject edges

Applications

• Signal conditioning circuits requiring specific bandpass filtering
• RF systems operating in high humidity or extreme temperature conditions
• Surface mount assembly for compact electronic devices

Procurement Notes

Verify the exact datasheet version and product change notifications prior to procurement. Confirm that the ordering suffix matches the required specifications, as suffixes may indicate packaging or minor revisions without altering core function. Ensure compatibility with the intended PCB layout guidelines provided by the manufacturer to maintain electrical performance.

Selection Notes

Select this component when a 2100-2900 MHz passband is required with minimal size constraints. The LTCC construction suits applications needing durability against environmental stressors like heat and humidity. Consider the 1206 footprint and SMT mounting requirements during the design phase to ensure proper integration into the target circuit board.

Part Context

This part belongs to the BFCN series of LTCC bandpass filters from Mini-Circuits. These filters are engineered for miniature size and high repeatability. The series generally offers low insertion loss and good rejection characteristics, utilizing wrap-around terminations to reduce parasitic effects common in surface mount designs.

Replacement Considerations

Consult official substitution lists for verified alternatives. Generic cross-references should be validated against electrical parameters such as center frequency, bandwidth, and insertion loss before implementation.
