RF3355C

Overview

The RF3355C is a surface-acoustic-wave (SAW) filter manufactured by Murata Electronics, designed for front-end selectivity in radio frequency applications. It operates at a center frequency of 390.0 MHz with a bandwidth of 200 kHz. The component features low insertion loss and is housed in an SM-5050-8 surface-mount package. It supports board mounting and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides high selectivity for narrowband signal processing
• Compact surface-mount design for space-constrained layouts
• Low-loss performance for efficient signal transmission

Applications

• Wireless sensor networks operating in the sub-GHz band
• Industrial telemetry systems requiring reliable short-range communication
• Remote control devices utilizing 390 MHz frequency allocation

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity and pin alignment against the SM-5050-8 specification sheet prior to assembly. Ensure storage conditions maintain moisture sensitivity levels appropriate for surface-mount technology handling procedures.

Selection Notes

Select this component when designing circuits for 390 MHz ISM band applications requiring compact SAW filter solutions. Evaluate insertion loss specifications against system link budget requirements. Consider thermal stability characteristics for environments exceeding standard commercial temperature ranges.

Part Context

This part belongs to Murata's SAW filter portfolio, historically sourced from RF Monolithics before acquisition. It serves as a specialized passive component for filtering applications where size constraints and moderate selectivity are prioritized over wideband performance capabilities found in other filter technologies.
