402F200XXCLT

Crystals Overview

The CTS-Frequency Controls 402F200XXCLT is a surface-mount MHz crystal operating at a fundamental frequency of 20.0000 MHz. It features a frequency stability and tolerance of ±15ppm, with a load capacitance of 12pF and an equivalent series resistance (ESR) of 100 Ohms. The component utilizes a 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm and a maximum seated height of 0.55mm. It supports an operating temperature range of -20°C to 70°C and is RoHS3 compliant.

Crystals Feature Summary

• Fundamental mode operation for precise frequency generation
• Compact 4-SMD surface mount footprint for automated assembly
• Designed for stable performance within industrial temperature ranges

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• General-purpose digital circuit oscillators

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as this unit specifies 12pF rather than the common 8pF variant. Confirm that the ±15ppm stability meets system jitter requirements. Ensure the operating temperature range aligns with environmental conditions. Check datasheet for soldering profile recommendations to maintain reliability during reflow processes.

Crystals Selection Notes

Select this component when a 20 MHz fundamental crystal with 12pF load capacitance is required. Compare ESR values against oscillator driver strength capabilities. Consider the physical size constraints of the PCB layout relative to the 2x1.6mm package. Evaluate thermal requirements to ensure the -20°C to 70°C range suffices for the application environment.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls. The series offers various frequencies and load capacitances in a standardized small outline package. It serves as a passive frequency control element distinct from active oscillators, requiring an external oscillator circuit or microcontroller pin to generate the clock signal.

Crystals Replacement Considerations

The 402F200XXCKT is a parameter-equivalent alternative within the same series but specifies an 8pF load capacitance instead of 12pF. Direct substitution requires verifying if the circuit's stray capacitance allows for the difference in load capacitance without affecting frequency accuracy.
