C1E-38.400-8-1520-R

Crystals Overview

The C1E-38.400-8-1520-R is a microprocessor crystal unit manufactured by Aker Technology Corp. It operates at a fundamental frequency of 38.4 MHz with a frequency tolerance of ±15 ppm. The component features a load capacitance of 8 pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a low-profile, ceramic-metal seam weld package in a 4-SMD, No Lead configuration. The physical dimensions are specified as 2.0 mm by 1.6 mm, designed for surface mount applications.

Crystals Feature Summary

• Low profile ceramic-metal seam weld construction
• Designed for microprocessor clock applications
• Surface mount 4-pin configuration

Crystals Applications

• Microprocessor clock circuits
• Digital signal processing systems
• Embedded controller timing references

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency tolerance and packaging specifications. Confirm that the 4-SMD no-lead package matches the target PCB footprint requirements. Cross-reference the ESR and load capacitance values with the circuit design parameters to guarantee oscillator stability. Ensure compliance with RoHS directives if required by the final assembly standards.

Crystals Selection Notes

Select this component when a compact, low-profile crystal is required for high-frequency digital logic timing. The 38.4 MHz frequency suits standard baud rate generation and processor clocking needs. The 8 pF load capacitance must align with the oscillator circuit's input capacitance. Consider the ±15 ppm tolerance for applications requiring moderate frequency accuracy without active temperature compensation.

Crystals Part Context

This part belongs to the C1E series of surface mount crystals from Aker Technology Corp. The series is characterized by small form factors suitable for space-constrained electronics. Similar models in the lineup vary primarily in frequency, package size, and tolerance levels while maintaining the same ceramic-metal seam weld technology.

Crystals Replacement Considerations

Direct substitutes include other 38.4 MHz SMD crystals with matching 8 pF load capacitance and comparable ESR. Verify pin compatibility and mechanical height restrictions before swapping. Alternative packages may require adapter solutions or PCB redesigns.
