402F2001XIJT

Crystals Overview

The CTS-Frequency Controls 402F2001XIJT is a surface-mount fundamental mode quartz crystal resonator designed for precision frequency control applications. It operates at a nominal frequency of 20 MHz with a frequency tolerance and stability of ±10 ppm. The component features an equivalent series resistance (ESR) of 100 Ohms and is specified for a load capacitance of 9 pF. It utilizes a standard 4-SMD, no-lead package with dimensions of 2.00mm x 1.60mm and a maximum seated height of 0.55mm. The device is rated for an operating temperature range of -20°C to +70°C and complies with RoHS3 standards.

Crystals Feature Summary

• Fundamental mode crystal design ensuring high frequency stability and low phase noise characteristics.
• Compact 4-SMD no-lead package optimized for automated surface-mount assembly processes.
• Seam-welded construction providing reliable hermetic sealing for consistent performance.

Crystals Applications

• Microcontroller clock sources requiring precise timing references.
• Communication modules utilizing 20 MHz carrier or reference frequencies.
• Digital signal processing circuits needing stable oscillator inputs.

Crystals Procurement Notes

Verify the specific suffix 'XIJT' against official CTS documentation to confirm the 9pF load capacitance and ±10ppm tolerance, as these parameters distinguish this variant from other 402 series parts. Ensure compatibility with the target circuit's load capacitance requirements before integration. Check current availability status as components in this legacy series may have limited supply chains.

Crystals Selection Notes

Select this component when a 20 MHz fundamental crystal with tight ±10ppm stability is required in a small form factor. The 9pF load capacitance specification must match the oscillator circuit design to ensure accurate frequency output. Consider the -20°C to +70°C temperature range suitability for the intended operational environment compared to wider industrial grade alternatives.

Crystals Part Context

The 402F2001XIJT belongs to the CTS 402 series of surface-mount crystals, which are established solutions for frequency control. This series represents mature technology offering reliability and quality, though CTS notes that legacy products may not be recommended for new designs if updated alternatives are available. The part shares the standard 2.0mm x 1.6mm footprint common across many devices in this family.

Crystals Replacement Considerations

Public confirmed substitute part numbers are not provided in the source data. Users should consult CTS-Frequency Controls for current recommended replacements within the 402 series or newer generations, as legacy support status may affect long-term availability.
