SBR868M350S024

Overview

The SBR868M350S024 is a Surface Acoustic Wave (SAW) resonator manufactured by NextGen Components, designed for Sub-GHz wireless applications. It operates at a nominal center frequency of 868.35 MHz with a frequency tolerance of ±150 kHz. The device features a standard 3838 surface-mount package measuring 3.8 mm x 3.8 mm x 1.5 mm and utilizes a six-pin configuration. Key electrical specifications include an insertion loss of up to 2.0 dB, an unloaded Q factor of 9400, and a loaded Q factor of 1500 at 50 Ohms. It supports a maximum RF power of 15 dBm and exhibits an annual aging rate of ≤±10 ppm. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for stable oscillation in low-power wireless networks
• Optimized for industrial-grade reliability with high Q-factor performance and minimal phase noise
• Compatible with standard SMT manufacturing processes including reflow soldering at 260°C

Applications

• 868 MHz LoRa and LoRaWAN nodes
• Sub-Gigabit wireless sensor modules
• Simple local oscillator circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct pinout and functional parameters. Confirm that the requested variant matches the required 3838 package dimensions and six-terminal configuration. Ensure compliance with RoHS III environmental standards if applicable to the target assembly. Cross-reference the frequency tolerance requirements with the system's demodulation sensitivity limits before finalizing the procurement order.

Selection Notes

Select this component when designing for EU868 band protocols requiring precise frequency stability without external calibration. The high unloaded Q factor makes it suitable for applications demanding low phase noise and fast startup times. Consider the thermal characteristics and aging rate for long-term deployments in outdoor or automotive environments where frequency drift must remain within strict operational bounds over several years.
