Resonators Procurement Notes

Verify the specific suffix Z against official Murata documentation to confirm any variations in material composition or environmental compliance compared to standard variants. Ensure the selected packaging format matches production requirements, as availability may vary between cut tape and reel configurations depending on the distributor source.

Resonators Selection Notes

Select this component when a stable 7.37 MHz reference is required with minimal external circuitry. The 15 pF internal capacitance must align with the host oscillator circuit's requirements. Consider the extended temperature range up to 125°C if the application involves harsh thermal environments compared to standard industrial grades.
