SF2150E

Overview

The SF2150E is a Surface Acoustic Wave (SAW) filter manufactured by Murata Electronics, designed for wireless RF applications. It operates at a center frequency of 915 MHz with a bandwidth of 10 MHz and an insertion loss of 3 dB. The component utilizes a 6-SMD, no-lead package configuration. It supports surface mount technology (SMD/SMT) termination types and functions within a temperature range of -40°C to +85°C. The device presents a standard impedance characteristic suitable for signal conditioning circuits in communication systems.

Feature Summary

• Surface Acoustic Wave technology for efficient RF signal filtering
• Optimized for low-loss performance in wireless communication bands
• Compact surface-mount package design for automated assembly

Applications

• Wireless RF signal processing
• Signal conditioning in communication modules
• Frequency selection in 915 MHz band devices

Procurement Notes

Verify current availability status as the component is listed as obsolete or end-of-life in major distributor databases. Confirm compatibility with existing PCB layouts and soldering profiles if sourcing from remaining stock. Check for official replacement recommendations from Murata Electronics to ensure long-term supply chain stability and technical equivalence for new designs.

Selection Notes

Select this component only for legacy designs requiring a 915 MHz SAW filter with specific 10 MHz bandwidth constraints. Evaluate thermal management requirements against the specified operating temperature range. Ensure interface impedance matches system requirements. Consider obsolescence risks when planning production volumes and lifecycle support duration for the final product.

Part Context

The SF2150E belongs to Murata's SAW filter family, specifically targeting ISM band applications. It is part of a broader portfolio of signal conditioning components used in RF front-end modules. This series emphasizes compact form factors and reliable performance for wireless transmission standards operating around 915 MHz.

Replacement Considerations

Consult Murata Electronics for officially confirmed substitute part numbers due to the obsolete status. Verify electrical parameter equivalence including center frequency, bandwidth, and insertion loss before implementation.
