FI212B245025-T

Overview

The FI212B245025-T is a multilayer ceramic bandpass RF filter manufactured by Taiyo Yuden. It operates with a center frequency of 2450 MHz and a bandwidth of 100 MHz. The component features an insertion loss of 1.4 dB and a ripple of 1 dB. It is housed in a surface-mount 0805 (2012 metric) package designed for board mounting.

Feature Summary

• Multilayer ceramic construction for high-frequency signal filtering
• Bandpass configuration optimized for specific center frequencies
• Surface-mount design suitable for automated assembly processes

Applications

• Wireless local area network (WLAN) systems
• Bluetooth communication modules
• ISM band radio frequency applications

Procurement Notes

Verify the current lifecycle status before procurement, as obsolescence notifications may apply to this series. Confirm that the 0805 package dimensions align with the target PCB footprint. Ensure compatibility with standard reflow soldering profiles specified in the official datasheet to maintain electrical performance and mechanical integrity during assembly.

Selection Notes

Select this component when a 2450 MHz center frequency with 100 MHz bandwidth is required. The 1.4 dB insertion loss makes it suitable for applications prioritizing signal fidelity over extreme attenuation. The 0805 package offers a balance between size constraints and handling ease compared to smaller footprints like 0402.
