402F54033CAR

Crystals Overview

The CTS-Frequency Controls 402F54033CAR is a surface-mount fundamental crystal oscillator operating at a nominal frequency of 54 MHz. It features a frequency stability of ±30 ppm and a load capacitance of 10 pF. The component utilizes a standard 2.0mm x 1.6mm seam-weld package with four SMD no-lead terminals. It exhibits an equivalent series resistance (ESR) of 60 Ohms and is designed for high-frequency timing applications within the 16MHz to 60MHz range.

Crystals Feature Summary

• Fundamental mode crystal design housed in a compact 2.0mm x 1.6mm seam-weld package
• High frequency stability of ±30 ppm for precise timing requirements
• Surface-mount configuration with four no-lead terminals for automated assembly

Crystals Applications

• Precision timing circuits requiring stable 54 MHz reference
• High-frequency digital systems utilizing fundamental crystal oscillators
• Embedded electronics demanding compact surface-mount timing components

Crystals Procurement Notes

Verify the specific suffix CAR against the official CTS datasheet to confirm exact load capacitance and tolerance specifications. Ensure compatibility with reflow soldering profiles suitable for seam-weld packages. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated assemblies.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency with ±30 ppm stability is required in a small form factor. The 10 pF load capacitance and 60 Ohm ESR must match the oscillator circuit design. Consider the 2.0mm x 1.6mm package dimensions for PCB layout constraints compared to larger leaded alternatives.

Crystals Part Context

This part belongs to the CTS Model 402 series, which covers frequencies from 16MHz to 60MHz. The series is characterized by fundamental crystal designs in standard seam-weld packages. The 402F54033CAR specifically targets the 54 MHz segment with defined electrical parameters for surface-mount applications.

Crystals Replacement Considerations

Cross-reference with other 402 series variants such as 402F54033CDR or 402F54033CLR if different load capacitances are acceptable. Verify that substitute parts maintain the same 54 MHz frequency, ±30 ppm stability, and 60 Ohm ESR specifications.
