402F50011CJR

Crystals Overview

The 402F50011CJR is a surface-mount MHz crystal manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 50 MHz with a frequency stability and tolerance of ±10 ppm. The component features a load capacitance of 9 pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm and a maximum height of 0.55mm. The device supports base harmonic operation and functions 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 packaging
• Compliant with RoHS3 environmental standards

Crystals Applications

• General purpose clock signal generation in electronic circuits
• Frequency reference sources for microcontroller systems
• Timing components in consumer electronics devices

Crystals Procurement Notes

Verify the specific load capacitance requirement of 9 pF against the target circuit design, as this differs from other variants in the 402 series. Confirm that the operating temperature range of -20°C to +70°C meets the application's environmental constraints. Ensure the PCB footprint matches the 2.00mm x 1.60mm SMD package dimensions. Check current availability status as supply levels may vary.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency crystal is required with a 9 pF load capacitance. The ±10 ppm stability suits applications needing moderate precision. Consider the 60 Ohm ESR value for oscillator circuit compatibility. The 4-SMD package is suitable for automated surface mount assembly processes requiring small form factors.

Crystals Part Context

This part belongs to the CTS 402 Series of MHz crystals, designed for surface mount applications. The series offers various frequency and capacitance options within a standardized small outline package. The 402F50011CJR specifically addresses needs for 50 MHz timing with 9 pF loading, distinguishing it from variants like the 402F50011CAT which uses 10 pF.

Crystals Replacement Considerations

Public confirmed substitutes include 402F50011CKR and 402F50011CLR. Verify that these alternatives maintain the identical 9 pF load capacitance and 50 MHz frequency specification before substitution.
