FAR-F6KA-1G5859-D4MS-Z

Overview

The FAR-F6KA-1G5859-D4MS-Z is a Surface Acoustic Wave (SAW) filter manufactured by Taiyo Yuden, designed for signal conditioning in RF applications. It operates at a center frequency of 1.5859 GHz with an insertion loss of 1 dB. The component utilizes a 5-pin SMD/SMT package with dimensions of 1.4 mm x 1.0 mm x 0.5 mm. It supports RoHS compliance and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Surface Acoustic Wave technology for precise RF signal filtering
• Compact 5-pin surface mount design for space-constrained PCBs
• Optimized for GPS L1 band frequency stability

Applications

• GPS receiver front-end modules
• GNSS positioning systems
• Mobile communication devices requiring L1 band filtering

Procurement Notes

Verify the specific suffix D4MS against current datasheets to confirm pinout and termination specifications. Confirm availability status as distribution channels may list obsolete or discontinued stock. Ensure ESD handling protocols are followed during assembly due to the sensitive SAW element structure.

Selection Notes

Select this component when a low-profile SAW filter is required specifically for the 1.5859 GHz GPS L1 frequency. Compare electrical performance against alternative F6 series variants if different insertion loss or bandwidth characteristics are needed. Verify that the 1.4x1.0x0.5mm footprint matches the target PCB layout constraints.

Part Context

This part belongs to the Taiyo Yuden F6 series of SAW filters, which are engineered for compact wireless communication equipment. The series typically offers high selectivity and low insertion loss for mobile phone and GNSS applications. The specific model targets the global positioning system L1 band requirements.

Replacement Considerations

Public records indicate FSSCSR4V1G58D4MS as a previous part number for this device. Verify compatibility with existing designs before substitution.
