BFCN-2491+

Overview

The BFCN-2491+ is an LTCC bandpass filter manufactured by Mini-Circuits. It operates within a frequency range of 1950 MHz to 3190 MHz with a center frequency of 2491 MHz. The component features a 50 Ohm impedance and utilizes a 1206 (3216 Metric) surface-mount package. It provides high suppression performance, specifically 22 dB and 29 dB attenuation levels. The design incorporates wrap-around terminations to minimize performance variations.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for miniature size and high repeatability
• Incorporates wrap-around terminations to minimize variations in performance
• Provides high suppression performance for signal purity

Applications

• RF communication systems
• Signal filtering applications requiring high suppression
• Evaluation board testing

Procurement Notes

Verify the specific datasheet version and compliance status (RoHS/REACH) before procurement. Confirm that the 1206 package dimensions align with your PCB layout requirements. Ensure the operating frequency range matches your system specifications. Check for available evaluation boards if prototyping is required. Validate supplier authenticity to ensure component quality.

Selection Notes

Select this component when a compact bandpass filter is needed for frequencies between 1950 MHz and 3190 MHz. The 50 Ohm impedance makes it suitable for standard RF circuits. Consider the LTCC construction for stability and the 1206 footprint for space-constrained designs. Evaluate the required suppression levels against the specified 22 dB and 29 dB performance points.
