Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required tolerance and temperature range specifications. Confirm that the 4-SMD footprint matches the target PCB design constraints. Request updated documentation directly from Geyer Electronic America or authorized distributors to validate current manufacturing status and compliance certifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a cost-effective ceramic solution is preferred over quartz for general-purpose timing applications. Ensure the system environment remains within the specified operating temperature range to maintain the ±10 ppm accuracy. Evaluate the 12 pF load capacitance requirement against the oscillator circuit design to guarantee proper oscillation startup and stability without additional external tuning components.

Crystals Part Context

This part belongs to Geyer Electronic's standard line of surface-mount ceramic resonators. These components are widely used in consumer electronics and industrial equipment where moderate frequency precision is sufficient. The 12.85635 designation refers specifically to the center frequency, distinguishing it from other variants in the series with different frequencies or package sizes.

Crystals Replacement Considerations

Direct substitutes must match the 12.85635 MHz frequency, 4-SMD package, and 12 pF load capacitance. Verify ESR compatibility with the host oscillator circuit. Cross-reference with other manufacturers' ceramic crystals offering similar tolerance and package dimensions if supply chain constraints require alternative sourcing.
