RF3319D

Overview

The RF3319D is a surface-acoustic-wave (SAW) filter manufactured by Murata Electronics, designed for front-end selectivity in receivers operating at 868.95 MHz. It features a low-loss design with a typical insertion loss of 2.2 dB and a bandwidth of 650 kHz. The component supports a voltage rating of 12 V and utilizes an 8-SMD, no-lead package.

Feature Summary

• Provides front-end signal selectivity for specific frequency bands
• Utilizes surface-acoustic-wave technology for low-loss performance
• Compact form factor suitable for space-constrained designs

Applications

• 868.95 MHz receiver front-ends
• Remote control systems
• Industrial, scientific, and medical (ISM) radio equipment

Procurement Notes

Verify the exact datasheet version to confirm electrical characteristics such as insertion loss and bandwidth. Ensure the 8-SMD no-lead package matches the target PCB footprint. Confirm RoHS compliance status if required by project specifications. Cross-reference the manufacturer part number to avoid counterfeit components.

Selection Notes

Select this component when designing circuits requiring precise filtering at 868.95 MHz. Consider the 2.2 dB insertion loss impact on overall system sensitivity. Evaluate the 650 kHz bandwidth against adjacent channel interference requirements. Verify that the 12 V voltage rating exceeds the maximum circuit operating voltage.

Part Context

This SAW filter belongs to Murata's lineup of signal conditioning components for RF applications. It addresses the need for compact, high-performance filtering in wireless communication devices. The device complements other passive components like capacitors and inductors in RF front-end modules.

Replacement Considerations

Check for direct substitutes from Murata or other manufacturers offering identical 868.95 MHz center frequencies and similar 8-SMD packages. Verify pin compatibility and electrical parameter equivalence before substitution.
