402F374XXCAT

Crystals Overview

The CTS-Frequency Controls 402F374XXCAT is a surface-mount crystal oscillator operating at a fundamental frequency of 37.4 MHz. It features a frequency stability and tolerance of ±15ppm, with a specified load capacitance of 10pF and an equivalent series resistance (ESR) of 60 Ohms. The component utilizes a 4-SMD, no-lead package with dimensions of 2.00mm x 1.60mm and a maximum height of 0.55mm. Designed for base mode operation, it supports a standard operating temperature range of -20°C to +70°C.

Crystals Feature Summary

• Provides precise timing signals at 37.4 MHz with high frequency stability.
• Compact surface-mount design suitable for space-constrained PCB layouts.
• Operates in fundamental mode with low equivalent series resistance.

Crystals Applications

• Clock generation for microcontrollers and digital logic circuits
• Communication interface timing sources
• Consumer electronics requiring stable frequency references

Crystals Procurement Notes

Verify the specific suffix CAT against official CTS documentation to confirm the 10pF load capacitance specification. Ensure the selected variant matches the required 60 Ohm ESR and ±15ppm stability for the target application environment. Cross-reference the 4-SMD package dimensions with the board layout constraints before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with tight ±15ppm stability. The 10pF load capacitance must match the circuit design requirements. Consider the -20°C to +70°C temperature range suitability. The compact 2.00mm x 1.60mm footprint is ideal for dense surface-mount assemblies where leaded packages are not feasible.

Crystals Part Context

This part belongs to the 402 series of surface-mount crystals from CTS-Frequency Controls. The series offers various frequencies and package sizes optimized for modern electronics. The 402F374XXCAT specifically addresses applications needing a 37.4 MHz reference with moderate stability and a small form factor.

Crystals Replacement Considerations

The 402F374XXCJR is a direct substitute within the same series, differing primarily in load capacitance (9pF vs 10pF). Verify circuit compatibility regarding load capacitance changes before swapping. Other 37.4 MHz crystals from different manufacturers require full electrical and mechanical re-validation.
