402F54011CAT

Crystals Overview

The CTS-Frequency Controls 402F54011CAT is a surface-mount crystal oscillator operating at a fundamental frequency of 54.0000 MHz. It features a load capacitance of 9 pF and an equivalent series resistance (ESR) of 60 Ohms. The component utilizes a 4-SMD, no-lead package configuration, designed for automated assembly processes. This specific variant provides stable frequency output suitable for timing applications in electronic circuits.

Crystals Feature Summary

• Surface-mount design for automated PCB assembly
• Stable frequency output for timing applications
• Low equivalent series resistance for efficient operation

Crystals Applications

• Timing source in low-power embedded designs
• Clock generation for microcontroller systems
• Synchronization in communication modules

Crystals Procurement Notes

Verify the exact load capacitance and ESR values against the official datasheet before integration. Confirm that the 4-SMD no-lead package dimensions match the target PCB footprint. Ensure soldering profiles comply with manufacturer recommendations for lead-free components to maintain reliability and prevent thermal damage during reflow processes.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency is required with a 9 pF load capacitance. Consider the 60 Ohm ESR for impedance matching requirements. Evaluate the 4-SMD no-lead package for space constraints and assembly automation needs compared to through-hole or other SMD variants within the same series.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls. The series offers various frequencies and package options. The 402F54011CAT specifically targets applications needing precise timing at 54 MHz with compact surface-mount form factors, differing from other suffixes like CKR or CAR which may have different capacitance or tolerance specifications.

Crystals Replacement Considerations

Direct substitutes include 402F54011CJR and 402F54011CKR, provided their respective load capacitances (9pF vs 8pF/10pF) and tolerances are compatible with the circuit design. Verify electrical parameters rather than assuming interchangeability based solely on the series name.
