402F38433CKR

Crystals Overview

The CTS-Frequency Controls 402F38433CKR is a surface-mount crystal resonator operating at a fundamental frequency of 38.4 MHz. It features a frequency stability of ±30 ppm and is designed for use with an external load capacitance of 8 pF. The component exhibits a maximum equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm. This device is intended for precise timing applications requiring stable frequency generation within standard commercial temperature ranges.

Crystals Feature Summary

• Provides stable frequency generation at 38.4 MHz with high precision
• Compact surface-mount design suitable for space-constrained PCB layouts
• Low equivalent series resistance ensures efficient circuit operation

Crystals Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Digital signal processing systems

Crystals Procurement Notes

Verify the specific load capacitance requirement of 8 pF against the target circuit design to ensure accurate frequency performance. Confirm that the 60 Ohm ESR limit aligns with the oscillator circuit's drive level specifications. Ensure the 4-SMD footprint matches the board layout silkscreen and pad dimensions. Check RoHS compliance status if environmental regulations apply to the final assembly.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is required for digital logic or communication protocols. The 8 pF load capacitance specification is critical; mismatched capacitors will cause frequency deviation. Consider the physical size constraints as the 2.00mm x 1.60mm package is small. Evaluate the ±30 ppm stability against the system's jitter tolerance requirements.

Crystals Part Context

This part belongs to the 402 series of SMD crystals from CTS-Frequency Controls. The series offers various frequencies and packages optimized for consumer electronics and industrial control. The 402F variant specifically denotes the 38.4 MHz frequency code within this family, standardized for common data rates and processor clocks.

Crystals Replacement Considerations

The 402F38433CAR is a parameter-equivalent alternative from the same manufacturer. Verify that the CAR variant maintains the identical 8 pF load capacitance and 60 Ohm ESR before substitution. Ensure the package dimensions are compatible with the existing footprint.
