RF3603D

Overview

The RF3603D is a Surface Acoustic Wave (SAW) bandpass filter manufactured by Murata Electronics. It operates at a center frequency of 316.4 MHz with a bandwidth of 13 MHz. The component features a nominal impedance of 50 Ohms and an insertion loss of 1.8 dB. It is housed in an 8-SMD, No Lead package with dimensions of 3.80mm x 3.80mm and a maximum height of 1.40mm. The device supports a voltage rating of 5 V and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Surface Acoustic Wave technology for precise signal filtering
• Compact surface-mount design suitable for space-constrained applications
• Low insertion loss characteristics for efficient signal transmission

Applications

• TRC105 transceiver signal conditioning
• RF front-end filtering in communication modules
• Bandpass filtering for specific frequency bands around 316 MHz

Procurement Notes

Verify component authenticity through authorized Murata distributors or certified suppliers. Confirm RoHS compliance status and check for obsolete lifecycle indicators, as the part may be discontinued. Ensure packaging specifications match production requirements, noting available options such as cut tape or reel formats. Validate datasheet revisions against current manufacturing standards before integration into designs.

Selection Notes

Select this component when a 316.4 MHz SAW filter is required for TRC105-based systems. Consider the 8-SMD package size for PCB layout constraints. Evaluate thermal performance within the specified -40°C to +85°C operating range. Compare insertion loss and bandwidth requirements against system specifications to ensure compatibility with adjacent circuitry and signal integrity needs.

Part Context

The RF3603D belongs to Murata's RF series of SAW filters, designed for specific frequency applications. It is categorized under signal conditioning components, specifically bandpass filters. The part is associated with the TRC105 transceiver ecosystem, indicating its role in specialized radio frequency infrastructure rather than general-purpose consumer electronics.

Replacement Considerations
