SF1186E-1

Overview

The Murata Electronics SF1186E-1 is a Surface Acoustic Wave (SAW) filter designed for signal conditioning applications. It operates at a center frequency of 1.57542 GHz with a bandwidth of 2 MHz. The component features an insertion loss of 2.9 dB and a nominal impedance of 50 Ohms. It utilizes a 6-SMD, No Lead package for board mounting. The device supports surface mount technology (SMD/SMT) and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Surface Acoustic Wave (SAW) technology for RF signal filtering
• Optimized for GPS L1 band frequency reception
• Compact 6-SMD no-lead surface mount packaging

Applications

• GPS receiver front-end modules
• GNSS navigation systems
• Satellite positioning devices

Procurement Notes

Verify the current lifecycle status as the SF1186E-1 is listed as obsolete or discontinued by major distributors. Confirm RoHS compliance requirements, as sources indicate non-compliance for this specific part number. Ensure alternative components are identified if long-term supply stability is required for production designs.

Selection Notes

Select this component only if legacy compatibility with 1.57542 GHz GPS architectures is mandatory. Compare insertion loss and bandwidth specifications against newer Murata SAW filters in the SF series. Evaluate package footprint compatibility with existing PCB layouts before finalizing the design choice.
