BFCO-252+

Overview

The BFCO-252+ is a surface-mount LTCC bandpass filter manufactured by Mini-Circuits. It operates with a center frequency of 2450 MHz and a passband ranging from 2400 to 2500 MHz. The component features a 50 Ohm impedance and utilizes a 0402 (1005 Metric) package. Key electrical specifications include an insertion loss of 3.7 dB and a maximum height of 0.017 inches (0.43 mm).

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for compact surface-mount integration.
• Provides precise signal conditioning within the 2400 to 2500 MHz frequency range.
• Designed for high-density PCB layouts using the standard 0402 footprint.

Applications

• Wireless communication systems requiring 2.4 GHz filtering.
• RF front-end modules in mobile devices.
• Industrial, Scientific, and Medical (ISM) band equipment.

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update technical parameters over time. Confirm that the 0402 package dimensions align with your PCB assembly capabilities. Ensure compatibility with RoHS standards if required by your manufacturing process. Cross-reference the part number suffix to confirm it matches the exact specification sheet provided by the manufacturer.

Selection Notes

Select this component when a narrow bandpass characteristic is required around 2.45 GHz. The 0402 size is suitable for space-constrained designs. Compare insertion loss values against system noise budget requirements. Consider the physical height constraint of 0.43 mm for low-profile applications. Evaluate thermal management needs based on the ceramic substrate properties.

Part Context

This model belongs to the BFCO series of LTCC bandpass filters from Mini-Circuits. Similar models like BFCG-252+ and BFCW-252+ share the same frequency range but differ in insertion loss characteristics. The BFCO variant offers specific attenuation profiles suited for general-purpose RF filtering tasks in consumer electronics.

Replacement Considerations

Direct substitutes include BFCG-252+ and BFCW-252+, which share the same footprint and frequency range. Verify insertion loss differences, as these variants offer 1.7 dB and 3.0 dB respectively. Ensure pinout compatibility remains identical across the series before swapping components in existing designs.
