402F20022IJR

Crystals Overview

The CTS-Frequency Controls 402F20022IJR is a surface-mount MHz crystal designed for precise timing applications. It operates at a fundamental frequency of 20 MHz with a frequency stability and tolerance of ±20ppm. The component features a load capacitance of 9pF and an equivalent series resistance (ESR) of 100 Ohms. Housed in a compact 4-SMD, No Lead package measuring 2.00mm x 1.60mm x 0.55mm maximum height, it supports operation within a temperature range of -40°C to 85°C. The device complies with RoHS3 standards and carries an MSL rating of 1.

Crystals Feature Summary

Crystals Procurement Notes

Verify the specific suffix IJR against official CTS documentation to confirm the 9pF load capacitance and 100 Ohm ESR parameters. Ensure the selected variant matches the required PCB land pattern for the 4-SMD no-lead package. Confirm RoHS3 compliance status if restricted substance regulations apply to the final assembly.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±20ppm stability is required. The 9pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR value for drive level sensitivity. The 4-SMD package size suits space-constrained designs requiring surface-mount technology compatibility.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and package options. The 402F20022IJR specifically targets applications needing a 20 MHz reference. It shares the standard 2.00mm x 1.60mm dimensions with other members of the family.

Crystals Replacement Considerations

Direct substitutes include 402F20022IAR and 402F20022ILT from CTS-Frequency Controls. Parametric equivalents such as 402F20012ILR may also be considered if specifications align. Verify pinout and electrical parameters before substitution.
