Resonators Procurement Notes

Verify the specific suffix G53 against official Murata documentation to confirm the 15 pF load capacitance and 60 Ohm impedance characteristics. Ensure the ordering part number matches the required operating temperature range of -20°C to +80°C. Confirm RoHS compliance status through current manufacturer declarations prior to final procurement decisions.

Resonators Selection Notes

Select this component when circuit board space is limited and external load capacitors are undesirable. The built-in capacitor simplifies layout and reduces component count. Verify that the target microcontroller or oscillator circuit can drive the specified 60 Ohm load resistance. Ensure the application environment remains within the standard commercial temperature limits.
