Crystals Procurement Notes

Verify the specific package dimensions and pinout configuration against the target PCB footprint prior to integration. Confirm that the 12.5 pF load capacitance aligns with the oscillator circuit requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly. Cross-reference the manufacturer's latest datasheet for any updates on material composition or compliance certifications.

Crystals Selection Notes

Select this component when a standard 32.768 kHz surface-mount solution is required for low-frequency timing applications. The ±20 ppm tolerance suits general-purpose clocks where high precision is not critical. Consider the 50 kOhm ESR limit to ensure adequate drive level compatibility with the host oscillator circuit. Evaluate the physical size constraints of the 4-SOJ package against available board space.

Crystals Part Context

This part belongs to the MMD crystal resonator family, specifically engineered for cost-effective timing solutions. It complements other components in the manufacturer's portfolio by providing a reliable SMT option for 32.768 kHz frequencies. The product line targets industries requiring standardized frequency control elements for mass-produced electronic devices.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 12.5 pF load capacitance, and 4-SOJ package form factor. Verify equivalent electrical parameters such as ESR and tolerance before substitution. Generic replacements may differ in mounting reliability or temperature stability characteristics.
