416F50022ALR

Overview

The CTS-Frequency Controls 416F50022ALR is a surface-mount AT-cut quartz crystal resonator operating at a fundamental frequency of 50 MHz. It features a frequency stability and tolerance of ±20 ppm, with a specified load capacitance of 12 pF and an equivalent series resistance (ESR) of 60 Ohms. The component utilizes a 4-SMD, no-lead package with dimensions of 1.60 mm in length, 1.20 mm in width, and a maximum height of 0.45 mm. It supports base harmonic operation within a temperature range of -20°C to +70°C.

Feature Summary

• Compact 4-SMD no-lead surface mount design for automated assembly
• Fundamental mode AT-cut quartz resonance for stable oscillation
• RoHS compliant construction without lead content

Applications

• Clock signal generation for microcontrollers and processors
• Frequency reference sources for communication modules
• Timing circuits in consumer electronic devices

Procurement Notes

Verify the specific suffix 'ALR' against the manufacturer's current datasheet to confirm active status and environmental compliance details. Ensure the 12 pF load capacitance matches the target oscillator circuit requirements. Check for any recent obsolescence notices or recommended replacement part numbers from CTS-Frequency Controls prior to finalizing procurement plans.

Selection Notes

Select this component when a 50 MHz fundamental frequency with ±20 ppm stability is required in a compact SMD form factor. Confirm that the system oscillator circuit is designed for a 12 pF load capacitance and can accommodate a 60 Ohm ESR. Verify that the -20°C to +70°C operating temperature range meets the application's environmental constraints.

Part Context

This part belongs to the CTS 416 Series of miniature crystals, designed for space-constrained applications. The series offers various frequencies and load capacitances in a standardized 1.6x1.2 mm footprint, facilitating consistent board layout across different product designs within the same family.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include 416F50022CAR and 416F50022CLT from CTS-Frequency Controls.
