AFII-LC-0044

Overview

The AFII-LC-0044 is a surface-mount bandpass filter manufactured by Abracon LLC, designed for signal conditioning in RF applications. It operates within the 2.4GHz to 2.5GHz frequency range, with a center frequency of 2.45GHz. The component utilizes a 0805 [2012 Metric] package, measuring 2.0 x 1.25 x 0.9 mm, and features a 3-pin configuration. It exhibits an insertion loss of 1.2 dB and supports a power handling capacity of 3W. This high-rejection ceramic filter is optimized for SMD assembly.

Feature Summary

• High rejection bandpass filtering capability centered at 2.45GHz
• Compact 0805 surface-mount footprint for space-constrained designs
• Robust 3W power handling capacity for reliable operation

Applications

• Wireless LAN (WLAN) systems operating in the 2.4GHz ISM band
• Bluetooth communication modules requiring signal isolation
• Zigbee and other IEEE 802.15.4 based wireless networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and tolerance specifications. Confirm that the 0805 package dimensions align with your PCB footprint library. Check for any recent revisions to the technical documentation that may affect performance parameters or recommended soldering profiles before finalizing procurement.

Selection Notes

Select this component when a compact, high-power bandpass filter is required for the 2.4GHz ISM band. The 0805 package size offers a balance between performance and board real estate. Ensure the application environment supports the specified 3W power rating and that the 1.2 dB insertion loss meets system link budget requirements. Verify compatibility with standard reflow soldering processes for SMD components.

Part Context

This part belongs to Abracon's line of SMD Bandpass Ceramic Filters, which are engineered for high-performance RF signal conditioning. These filters are characterized by their small form factor and stable electrical properties across temperature variations. The AFII series is specifically tailored for modern wireless communication standards that demand precise frequency selection and interference rejection in compact electronic devices.

Replacement Considerations

The AFII-LC-0045 is a documented alternative from the same manufacturer family, offering similar bandpass characteristics but with different physical dimensions (2.5mm length). Verify pinout compatibility and exact frequency response curves before substitution.
