RF3171D

Overview

The RF3171D is a Surface Acoustic Wave (SAW) filter manufactured by Murata Electronics, designed for narrowband receiver front-end applications. It operates at a center frequency of 418.0 MHz and features an 8-SMD package without lead. The component exhibits a typical insertion loss of 1.6 dB and maintains a bandwidth of 620 kHz. It is RoHS compliant and lead-free, suitable for signal conditioning in remote control systems.

Feature Summary

• Surface Acoustic Wave technology for precise signal filtering
• Optimized for narrowband receiver front-end applications
• Compact 8-SMD surface mount package design

Applications

• Remote control receiver circuits
• Narrowband signal conditioning
• RF front-end filtering

Procurement Notes

Verify the specific suffix and package variant against the official Murata datasheet to ensure compatibility with your PCB footprint and assembly requirements. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Ensure storage conditions meet moisture sensitivity level specifications upon receipt.

Selection Notes

Select this component when a fixed 418.0 MHz SAW filter is required for remote control applications. Consider the 620 kHz bandwidth and 1.6 dB insertion loss characteristics against system sensitivity requirements. Evaluate the 8-SMD package dimensions for space constraints. Compare performance metrics with alternative SAW filters if different center frequencies or bandwidths are needed.

Part Context

This component belongs to Murata's SAW filter portfolio, specifically engineered for low-cost, high-performance signal conditioning. It serves as a critical element in defining channel selectivity for receivers operating in the 418 MHz band. The device integrates acoustic wave propagation principles to achieve sharp cutoff characteristics within a small form factor.

Replacement Considerations

Check for direct substitutes with identical 418.0 MHz center frequency and 8-SMD footprint. Verify that any replacement maintains the 620 kHz bandwidth and similar insertion loss values. Ensure pinout compatibility and mechanical dimensions match the existing design to prevent rework.
