FSSCSR1T1G58P2BQ-AJ

Overview

The FSSCSR1T1G58P2BQ-AJ is a Surface Acoustic Wave (SAW) filter manufactured by Taiyo Yuden, designed for signal conditioning applications. It operates at a center frequency of 1.58 GHz and features a typical insertion loss of 1.7 dB. The component utilizes a balanced termination impedance and is housed in a compact 5-pin SMD package with no leads, suitable for board mounting. It supports surface mount technology (SMD/SMT) and functions within a maximum operating temperature range of +85°C. This device belongs to the FSSC series and is intended for precise frequency selection in communication systems.

Feature Summary

• Utilizes Surface Acoustic Wave (SAW) technology for effective signal filtering
• Designed for balanced termination impedance applications
• Compact 5-pin leadless surface mount package design

Applications

• GPS system signal conditioning
• GNSS receiver front-end filtering
• Satellite navigation signal processing

Procurement Notes

Verify the specific suffix -AJ against official Taiyo Yuden documentation to confirm packaging and handling specifications. Ensure compatibility with the target PCB footprint for the 5-pin SMD configuration. Cross-reference the center frequency and insertion loss requirements with the application datasheet to validate performance suitability for the intended GPS or GNSS circuit design.

Selection Notes

Select this component when a low-profile SAW filter is required for 1.58 GHz operations with balanced output requirements. Consider the 1.7 dB insertion loss specification relative to system sensitivity needs. Evaluate the 5-pin SMD package dimensions against available board space constraints. Confirm that the +85°C maximum operating temperature aligns with the environmental conditions of the final assembly.

Part Context

This part belongs to the Taiyo Yuden FSSC series of SAW filters, which are engineered for high-frequency signal processing. The series targets mobile and satellite communication devices requiring compact form factors. The 1.58 GHz frequency band is specifically aligned with Global Navigation Satellite System (GNSS) signals, distinguishing it from cellular or Wi-Fi focused filter variants within the broader product portfolio.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Taiyo Yuden technical support for direct equivalents or pin-compatible alternatives that meet the 1.58 GHz center frequency and balanced impedance specifications.
