Crystals Procurement Notes

Verify that the specific part number suffix matches the required frequency tolerance and stability specifications for your application. Confirm that the load capacitance aligns with the host circuit design to prevent frequency deviation. Ensure the operating temperature range meets the environmental requirements of the final product deployment.

Crystals Selection Notes

Select this component when a compact SMD crystal is needed for industrial environments requiring precise timing. The 80 Ω ESR limit must be compatible with the oscillator circuit's impedance matching capabilities. Consider the 10 µW drive level to ensure long-term aging stability and prevent over-driving the crystal element during operation.

Crystals Part Context

This component belongs to the MMD T series of surface-mount crystals, designed for general-purpose timing applications. The series offers various frequencies within the 12 MHz to 54 MHz range, utilizing standard 3225-like footprints.
