416F50023CST

Overview

The CTS-Frequency Controls 416F50023CST is a 50 MHz fundamental mode crystal resonator designed for surface-mount applications. It features a frequency tolerance of ±20ppm and stability of ±30ppm, with an equivalent series resistance (ESR) of 60 Ohms. The component utilizes a 4-SMD, no-lead package measuring 1.60mm x 1.20mm x 0.45mm maximum height. It operates within a temperature range of -40°C to +85°C and has a load capacitance specification associated with the series configuration.

Feature Summary

• Fundamental mode operation for precise frequency generation
• Compact 4-SMD no-lead footprint suitable for automated assembly
• Wide operating temperature range supporting industrial environments

Applications

• General purpose clock signal generation in digital circuits
• Microcontroller and processor system oscillators
• Communication module timing references

Procurement Notes

Verify that the specific suffix 'CST' aligns with the required tape and reel packaging format for high-volume manufacturing processes. Confirm that the ±20ppm tolerance meets the system's jitter and phase noise requirements. Ensure the PCB land pattern matches the 1.60mm x 1.20mm dimensions to prevent soldering defects during reflow.

Selection Notes

Select this component when a fundamental mode crystal is preferred over overtone modes for simpler oscillator circuit design. The 60 Ohm ESR value must be compatible with the driving capability of the host oscillator IC. Consider the ±30ppm stability if the application requires tighter frequency control than standard consumer-grade crystals offer.

Part Context

This part belongs to the CTS 416 Series of miniature crystals. It is functionally similar to variants like 416F50023IKR but differs in packaging and specific suffix designations. The product line represents mature frequency control solutions from CTS, which are supported but may not be recommended for new designs requiring updated alternatives.

Replacement Considerations

Direct substitutes include 416F50023IAR and 416F50023ITR from CTS-Frequency Controls. These parts share identical electrical specifications and form factor, differing primarily in packaging or reel configuration.
