402F20011CJR

Crystals Overview

The CTS-Frequency Controls 402F20011CJR is a surface-mount quartz crystal resonator operating at a fundamental frequency of 20 MHz. It features a frequency stability and tolerance of ±10 ppm, with a load capacitance of 9 pF and an equivalent series resistance (ESR) of 100 Ohms. The component utilizes a standard 4-SMD, no-lead seam-weld package measuring 2.00 mm x 1.60 mm x 0.55 mm max. It supports a commercial operating temperature range of -20°C to +70°C and is packaged in tape and reel for automated assembly.

Crystals Feature Summary

• Fundamental mode operation within the 402 series standard 2.0mm x 1.6mm seam-weld package
• High frequency stability of ±10 ppm for precise timing applications
• Surface-mount design optimized for automated pick-and-place manufacturing processes

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits
• Consumer electronics timing control

Crystals Procurement Notes

Verify the specific suffix 'CJR' against the manufacturer's current datasheet to confirm packaging and material specifications. Check for obsolescence status or lifecycle changes directly with CTS-Frequency Controls, as distributor listings may not reflect real-time production availability. Ensure the 9pF load capacitance matches the host circuit design requirements before finalizing procurement.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±10 ppm stability is required in a compact 4-SMD footprint. The 100 Ohm ESR value must be compatible with the oscillator circuit's drive level constraints. Confirm that the -20°C to +70°C temperature range meets the operational environment specifications of the target application.

Crystals Part Context

This part belongs to the CTS 402 Series, which offers a range of fundamental mode crystals in a standardized small outline package. The series provides various frequencies and load capacitances, allowing designers to select components based on specific timing accuracy and size constraints while maintaining consistent mechanical dimensions across the family.

Crystals Replacement Considerations

Direct substitutes include 402F20011CAR and 402F20011CJT from CTS-Frequency Controls, provided they match the exact electrical parameters and package dimensions.
