402F200XXCDT

Crystals Overview

The CTS-Frequency Controls 402F200XXCDT is a fundamental mode MHz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 20 MHz with a frequency stability and tolerance of ±15ppm. The component features a load capacitance of 18pF and an equivalent series resistance (ESR) of 100 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm and a maximum seated height of 0.55mm. The device supports an operating temperature range of -20°C to 70°C and complies with RoHS3 standards.

Crystals Feature Summary

• Fundamental resonance mode operation for stable timing signals
• Compact 4-SMD no-lead surface mount package design
• Compliance with RoHS3 environmental standards

Crystals Applications

• General purpose clock signal generation in electronic circuits
• Timing reference for microcontrollers and processors
• Communication interface synchronization modules

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as this variant specifies 18pF rather than the common 8pF or 12pF values found in other series members. Confirm that the ±15ppm stability meets the system's jitter and drift requirements. Ensure the PCB footprint matches the 2.00mm x 1.60mm outline and 0.55mm height constraints to avoid mechanical interference during assembly.

Crystals Selection Notes

Select this component when a 20MHz fundamental mode crystal is required in a small surface-mount form factor. It is suitable for applications where moderate frequency stability is sufficient and space is constrained. Consider alternative packages if higher temperature ranges or different load capacitances are needed. This part is distinct from the ATS series which utilizes through-hole packaging and overtone modes.

Crystals Part Context

This component belongs to the CTS 402 Series of crystals, which are characterized by their small 4-SMD no-lead footprint. The series offers various frequency codes and load capacitance options to accommodate different oscillator circuit designs. The 402F200XXCDT specifically addresses the need for 20MHz timing in compact consumer and industrial electronics where leaded components are impractical.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 402F200XXCKT and 402F200XXCDR. Verify compatibility regarding load capacitance differences, as some substitutes may specify 8pF instead of 18pF. Ensure the replacement maintains the same fundamental mode operation and package dimensions for direct board integration.
