FSSCSR1T897MM2AC-AJ

Overview

The FSSCSR1T897MM2AC-AJ is a Surface Acoustic Wave (SAW) filter manufactured by Taiyo Yuden, designed for signal conditioning at a center frequency of 897 MHz. It operates within the Band 8 cellular spectrum and features a typical insertion loss of 2.3 dB with an attenuation of 28 dB. The component utilizes a 5-SMD, no-lead package with dimensions of 1.1 mm in length and a height of 0.50 mm. It supports unbalanced termination and functions reliably up to a maximum operating temperature of +85°C.

Feature Summary

• Low insertion loss and high attenuation characteristics optimized for efficient signal transmission
• Compact and low-profile package design suitable for space-constrained mobile devices
• High reliability ensured through hermetic sealing with Moisture Sensitivity Level 1 (MSL1)
• Environmentally conscious construction compliant with industry standards

Applications

• Cellular GSM systems operating in Band 8
• Mobile communication handsets requiring RF signal filtering
• IoT devices utilizing LTE or NB-IoT technologies in the 897 MHz range

Procurement Notes

Verify the specific suffix AJ against the manufacturer's latest datasheet to confirm pinout and marking variations. Ensure compatibility with SMD reflow processes given the no-lead termination style. Confirm that the 897 MHz center frequency aligns precisely with your target Band 8 implementation requirements before finalizing procurement.

Selection Notes

Select this SAW filter when designing for Band 8 cellular applications requiring minimal signal degradation. The 2.3 dB insertion loss makes it suitable for sensitive receiver chains. Its small 1.1 mm footprint allows integration into compact form factors. Verify that the unbalanced termination matches your circuit topology and that the 85°C thermal rating meets environmental specifications.

Part Context

This component belongs to the FSSC series of SAW filters from Taiyo Yuden, which are engineered for high-frequency signal conditioning. The series emphasizes low profile and high reliability, targeting modern wireless communication standards. It serves as a critical passive element in RF front-end modules, providing necessary frequency selectivity for cellular bands.

Replacement Considerations

Consult official Taiyo Yuden substitution guides for direct equivalents. Ensure any alternative maintains the 897 MHz center frequency, 5-SMD package, and similar electrical parameters such as insertion loss and attenuation levels to guarantee circuit performance continuity.
