C3E-8.000-18-1020-X-R

Crystals Overview

The C3E-8.000-18-1020-X-R is a parallel fundamental quartz crystal manufactured by Aker Technology Corp, operating at a nominal frequency of 8 MHz. It features a load capacitance of 18 pF and a maximum equivalent series resistance (ESR) of 500 Ohms. The component offers a frequency tolerance of ±10 ppm at 25°C and maintains a frequency stability of ±30 ppm over the -10 to +70°C temperature range. Designed for surface mount applications, it utilizes a 4-SMD, no lead package configuration.

Crystals Feature Summary

• Parallel fundamental mode oscillation for stable timing control
• Surface mount construction with a lead-free 4-pin SMD package
• Compliant with RoHS environmental standards

Crystals Applications

• General purpose clock signal generation in electronic circuits
• Timing reference for microcontroller systems
• Frequency control in consumer electronics devices

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required load capacitance and frequency tolerance specifications. Confirm that the 4-SMD package dimensions align with the target PCB footprint. Check for RoHS compliance documentation if environmental regulations apply to the end product. Ensure the drive level requirements are met by the host circuit design to prevent frequency instability or crystal damage during operation.

Crystals Selection Notes

Select this component when a precise 8 MHz reference is required for surface mount designs. The 18 pF load capacitance must match the oscillator circuit's input capacitance to achieve the specified ±10 ppm accuracy. Consider the 500 Ohm ESR limit when evaluating the driving capability of the connected logic family. The operating temperature range of -10 to +70°C suits standard commercial applications rather than harsh industrial environments requiring wider thermal margins.

Crystals Part Context

This part belongs to the C3E series of quartz crystals produced by Aker Technology Corp, a manufacturer specializing in frequency control products. The company focuses on quartz-based solutions for global electronics markets, including automotive-grade components. This specific model represents a standard commercial-grade crystal designed for general timing applications where moderate stability and compact surface mount packaging are prioritized.

Crystals Replacement Considerations

Direct substitutes must match the 8 MHz frequency, 18 pF load capacitance, and 4-SMD package form factor. Verify that alternative manufacturers offer comparable ±10 ppm tolerance and similar ESR characteristics to maintain circuit performance. Cross-reference pinout configurations to ensure mechanical compatibility without redesigning the PCB layout.
