SF2053E

Overview

The SF2053E is a Surface Acoustic Wave (SAW) bandpass filter manufactured by Murata Electronics. It operates within the 915 MHz ISM band, with a specified frequency range of 908.75 MHz to 921.25 MHz. The component features a 12.5 MHz bandwidth and maintains a 50-ohm impedance. It is housed in an SMD/SMT SM3030-6 package, designed for surface mount applications. The device supports a voltage rating of 3V and functions reliably across a temperature range from -40°C to +125°C.

Feature Summary

• Provides signal conditioning through SAW technology for precise frequency selection
• Optimized for operation within the 915 MHz ISM band
• Designed for compact surface-mount integration

Applications

• ISM band communication systems
• RF signal filtering in wireless modules
• Signal conditioning circuits requiring 915 MHz selectivity

Procurement Notes

Verify the specific manufacturer source, as listings may attribute this part to RFMI or Murata Electronics. Confirm RoHS compliance status and ensure the SM3030-6 package matches your PCB footprint requirements. Check for any regional shipping restrictions or discontinuation notices before finalizing procurement plans.

Selection Notes

Select this component when a narrow 12.5 MHz bandwidth is required at 915 MHz. Ensure the design accommodates the 3V voltage rating and the operating temperature limits of -40°C to +125°C. Verify that the 50-ohm impedance aligns with the system's RF interface specifications.

Part Context

This component belongs to the SF series of SAW filters. It serves as a passive RF element used to isolate specific frequencies in communication hardware. The SM3030-6 package allows for automated assembly in high-volume manufacturing environments.
