Resonators Procurement Notes

Verify the specific suffix 'A' against official Murata documentation to confirm exact tolerances and packaging specifications. Ensure compatibility with reflow soldering profiles defined in the datasheet. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference the part number with authorized distributors to avoid counterfeit components. Validate that the selected variant meets the thermal requirements of the target application environment.

Resonators Selection Notes

Select this component when a precise 6.14 MHz reference is required with minimal external circuitry. Consider the ±0.5% tolerance for applications needing tighter frequency accuracy than standard resonators. Evaluate the 50 Ohm impedance against the driving circuit capabilities of the host microcontroller or oscillator. Assess the physical dimensions to ensure adequate clearance on the printed circuit board layout.
