C7S-8.000-18-1030-R

Crystals Overview

The C7S-8.000-18-1030-R is a surface-mount quartz crystal oscillator manufactured by Aker Technology Corp. It operates at a standard frequency of 8 MHz with a frequency tolerance and stability of ±10 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 70 Ohms. It utilizes a 4-SMD, no-lead package configuration. The device is designed for applications requiring precise timing references in compact electronic systems.

Crystals Feature Summary

• Provides stable 8 MHz oscillation with high frequency accuracy
• Compact surface-mount design suitable for space-constrained PCB layouts
• Low equivalent series resistance for efficient circuit integration

Crystals Applications

• Baseband chip clock reference in mobile communication devices
• 5G communication system timing sources
• General-purpose digital circuit synchronization

Crystals Procurement Notes

Verify the specific suffix 'R' against the manufacturer's current datasheet to confirm packaging details and availability status. Ensure that the ±10 ppm tolerance meets the strict timing requirements of the target application. Cross-reference the 4-SMD package dimensions with the PCB footprint library to prevent assembly errors during manufacturing.

Crystals Selection Notes

Select this component when a precise 8 MHz reference is required with tight ±10 ppm stability. The 18 pF load capacitance must match the oscillator circuit design parameters. Consider the 70 Ohm ESR value for impedance matching. This part is suitable for consumer electronics where size constraints necessitate a small SMD form factor.

Crystals Part Context

This component belongs to the C7S series of quartz crystals from Aker Technology Corp. The series offers various frequency options and package sizes for different electronic applications. The C7S-8.000 variant specifically targets the 8 MHz market segment, providing a reliable alternative to larger through-hole crystals in modern miniaturized designs.

Crystals Replacement Considerations

Direct substitutes include C7S-8.000-18-1030-X-R and C7S-8.000-18-3030-X-R, which share similar electrical characteristics. Verify pin compatibility and load capacitance before substitution. Alternative brands may require re-evaluation of the oscillator circuit due to differences in ESR and drive level specifications.
