402F20422IJR

Crystals Overview

The CTS-Frequency Controls 402F20422IJR is a fundamental parallel quartz crystal designed for surface-mount applications. It operates at a nominal frequency of 20.48 MHz with a load capacitance of 9 pF and an equivalent series resistance (ESR) of 150 Ohms. The component provides a frequency tolerance of ±20 ppm and stability of ±30 ppm. It features a hermetic ceramic package measuring 2.0 mm x 1.6 mm x 0.55 mm, suitable for environments ranging from -40°C to +85°C.

Crystals Feature Summary

• Hermetic ceramic surface mount construction ensuring environmental reliability
• Fundamental AT-cut quartz design for stable oscillation
• Compact sub-miniature footprint optimized for high-density PCB layouts

Crystals Applications

• Digital signal processing clock sources
• Motor control system timing references
• Embedded microcontroller oscillator circuits

Crystals Procurement Notes

Verify the specific suffix 'IJR' against official CTS documentation to confirm lead time and availability status, as distribution channels may list varying stock levels or discontinuation notices. Ensure the 9 pF load capacitance matches the target circuit design requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20.48 MHz reference with tight ±20 ppm tolerance is required in a space-constrained design. The 150 Ohm ESR value must be compatible with the oscillator circuit's drive level limitations. Consider the hermetic seal if long-term aging stability is critical compared to non-hermetic alternatives.

Crystals Part Context

This part belongs to the CTS 402 Series, which specializes in sub-miniature surface-mount crystals. The series offers various frequency codes and package options within the 2.0 x 1.6 mm form factor, catering to modern electronics requiring small footprints and reliable frequency generation.

Crystals Replacement Considerations

Direct substitutes include 402F20422ILR and 402F20422IAR from CTS-Frequency Controls. Verify that alternative packages maintain the same 9 pF load capacitance and 150 Ohm ESR specifications to ensure circuit compatibility.
