Procurement Notes

Verify the specific suffix (e.g., -1) against official documentation to ensure correct load capacitance and tolerance specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability varies. Ensure the selected variant matches the required 418 MHz frequency and surface-mount package dimensions for PCB integration.

Selection Notes

Select this component for applications requiring a 418 MHz reference signal with high frequency stability. Consider the 30 VDC maximum rating and -40°C to +125°C operating range when designing for industrial or outdoor environments. The 4-SMD package is suitable for high-volume surface-mount assembly processes.
