Crystals Procurement Notes

Verify the specific electrical parameters against the official product datasheet prior to implementation. Confirm that the 4-SMD no lead package dimensions align with the target PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the final application. Cross-reference the manufacturer part number to avoid confusion with similar variants in the C7S series.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 8 MHz timing applications. The 18 pF load capacitance must match the oscillator circuit design specifications. Consider the 40 Ohm ESR value for drive level compatibility. Evaluate the ±10 ppm tolerance against system frequency accuracy requirements. Verify that the surface-mount form factor suits the manufacturing process constraints.

Crystals Part Context

This component belongs to the C7S series of quartz crystals produced by Aker Technology Corp. The series encompasses various frequencies and package options tailored for surface-mount technology.
