SAR868M350S035

Overview

The SAR868M350S035 is a Surface Acoustic Wave (SAW) resonator manufactured by NextGen Components. It operates at a center frequency of 868.35 MHz with a tolerance of +/-200 kHz. The device features an 8-pad surface mount package, specifically the QCC8C case code measuring 5.0mm x 5.0mm x 1.5mm. It presents a nominal impedance of 50 Ohms and functions as a single-port component. The operational temperature range spans from -40°C to +85°C, suitable for industrial applications.

Feature Summary

• Utilizes Surface Acoustic Wave technology for stable frequency generation in sub-GHz bands
• Designed with an 8-pad surface mount configuration for automated assembly compatibility
• Engineered for industrial-grade thermal stability across extended temperature ranges

Applications

• Sub-GHz wireless communication modules
• Industrial IoT sensor nodes
• Local oscillator circuits for RF transceivers

Procurement Notes

Verify that the required package matches the QCC8C specification (5.0x5.0x1.5mm). Confirm the frequency tolerance requirement aligns with the +/-200 kHz specification. Ensure the design supports single-port SAW resonator topologies. Check that the operating environment remains within the -40°C to +85°C range. Validate PCB footprint dimensions against manufacturer drawings prior to procurement.

Selection Notes

Select this component when a 5.0x5.0mm surface mount form factor is required for 868 MHz applications. Consider the 8-pad layout for improved thermal dissipation compared to smaller packages. Evaluate the +/-200 kHz tolerance against system frequency budget constraints. Ensure the 50 Ohm impedance matches the source circuit requirements. Verify compatibility with standard reflow soldering profiles for the specified height.

Part Context

This part belongs to the SAR series of SMD SAW resonators from NextGen Components. It shares the same physical dimensions and pad count as other variants in the 5050 type family. The series typically covers various sub-GHz frequencies while maintaining consistent mechanical footprints. This specific model targets the European 868 MHz ISM band allocation.

Replacement Considerations

Direct substitutes include other 868.35 MHz SAW resonators in the QCC8C package with comparable impedance. Verify equivalent frequency tolerance and temperature range before substitution. Cross-reference pinout configurations to ensure electrical compatibility. Consult manufacturer cross-reference lists for validated alternative part numbers.
