402F27011CJR

Crystals Overview

The CTS-Frequency Controls 402F27011CJR is a surface-mount quartz crystal resonator operating at a fundamental frequency of 27 MHz. It features a load capacitance of 9 pF and a frequency stability of ±10 ppm. The component has an equivalent series resistance (ESR) of 100 Ohms and operates within a temperature range of -20°C to +70°C. It utilizes a 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm and a maximum height of 0.55mm.

Crystals Feature Summary

• Fundamental mode operation for precise frequency control
• Compact 4-SMD no-lead surface mount design
• RoHS3 compliant construction

Crystals Applications

• General purpose clock generation circuits
• Microcontroller oscillator interfaces
• RF transmitter/receiver frequency references

Crystals Procurement Notes

Verify the specific suffix 'CJR' against the manufacturer's current datasheet to confirm the 9 pF load capacitance specification, as variations exist within the 402 series. Confirm availability status directly with authorized distributors, as supply levels fluctuate. Ensure the application circuit matches the 9 pF load requirement to maintain the specified ±10 ppm accuracy.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required in a compact SMD footprint. The 9 pF load capacitance distinguishes it from similar models like the 402F27011CKT which uses 8 pF. Verify that the target PCB layout supports the 2.00mm x 1.60mm package dimensions and that the operating environment stays within the -20°C to +70°C range.

Crystals Part Context

This part belongs to the CTS 402 Series of low-cost, general-purpose crystals. The series offers various frequency codes and load capacitances in a standardized small outline package. The 402F27011CJR specifically addresses applications needing 27 MHz timing with a 9 pF load requirement, providing a standard solution for consumer electronics and industrial control systems.

Crystals Replacement Considerations

The 402F27011CAR is listed as a similar alternative by the manufacturer. However, verify if the 'AR' suffix implies identical electrical parameters, particularly the 9 pF load capacitance and 100 Ohm ESR, before substitution.
