402F200XXCDR

Crystals Overview

The CTS-Frequency Controls 402F200XXCDR is a surface-mount MHz crystal operating at 20.0000 MHz with ±15ppm frequency tolerance and stability. It features an 18pF load capacitance and 100 Ohms equivalent series resistance (ESR). The component utilizes fundamental operating mode within a 4-SMD, No Lead package measuring 2.00mm x 1.60mm x 0.55mm. It supports an operating temperature range of -20°C to 70°C and complies with RoHS3 standards.

Crystals Feature Summary

• Fundamental mode operation for precise frequency generation
• Surface mount design in compact 4-SMD package
• Compliant with RoHS3 environmental standards

Crystals Applications

• General purpose clock signal generation
• Microcontroller system timing references
• Digital communication interface synchronization

Crystals Procurement Notes

Verify the specific suffix 'CDR' against official datasheets to confirm the 18pF load capacitance specification, as variations exist within the 402F series. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the selected variant matches the required PCB footprint dimensions of 2.00mm by 1.60mm for proper integration.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with 18pF load capacitance is required for space-constrained designs. Compare against the 402F200XXCKT variant if an 8pF load capacitance better suits the circuit design. Evaluate thermal requirements against the -20°C to 70°C operational range to ensure reliability under intended environmental conditions.

Crystals Part Context

This part belongs to the 402 Series of high-stability crystals from CTS-Frequency Controls. The series offers various frequencies and load capacitances in standardized SMD packages. The 402F200XXCDR specifically addresses applications needing 20 MHz timing with 18pF loading, differing from other series members like the 402F300XXCJR which operates at 30 MHz.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 402F200XXCKT and 402F200XXCAR. Verify that alternative suffixes match the required 18pF load capacitance and physical dimensions before substitution.
