402F20033CJT

Crystals Overview

The CTS-Frequency Controls 402F20033CJT is a surface-mount MHz crystal resonator operating at a fundamental frequency of 20.0000 MHz. It features a load capacitance of 9 pF and a frequency stability of ±30 ppm. The component utilizes a 4-SMD, no-lead package with dimensions of 2.00 mm x 1.60 mm and a maximum height of 0.55 mm. It exhibits an equivalent series resistance (ESR) of 100 Ohms and supports a base harmonic operating mode within a temperature range of -20°C to 70°C.

Crystals Feature Summary

• Fundamental mode operation for precise frequency generation
• Compact 4-SMD no-lead surface mount footprint
• RoHS3 compliant environmental certification

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Embedded system oscillators

Crystals Procurement Notes

Verify the specific suffix 'CJT' against official CTS datasheets to confirm packaging and tolerance specifications. Ensure compatibility with existing PCB land patterns for 4-SMD no-lead packages. Cross-reference RoHS3 status if environmental compliance is mandatory for the target assembly process.

Crystals Selection Notes

Select this component when a 20 MHz fundamental crystal with 9 pF load capacitance is required. Verify that the ±30 ppm stability meets system timing requirements. Confirm the 100 Ohm ESR matches the oscillator circuit design constraints and that the 4-SMD form factor fits the available board space.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various frequencies and package sizes designed for general-purpose timing applications. The 402F20033CJT specifically addresses needs for compact 20 MHz reference signals in consumer and industrial electronics requiring standard SMD mounting.

Crystals Replacement Considerations

Direct substitutes include 402F20033CJR and 402F20033CLR from CTS-Frequency Controls. These alternatives share identical electrical parameters but may differ in packaging type or reel configuration. Verify pinout and mechanical dimensions before substitution.
