416F50022IAR

Overview

The CTS-Frequency Controls 416F50022IAR is a surface-mount quartz crystal resonator operating at a fundamental frequency of 50 MHz. It features a load capacitance of 10 pF and a frequency stability of ±20 ppm. The component utilizes a 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm and a maximum height of 0.45mm. It exhibits an equivalent series resistance (ESR) of 60 Ohms and supports operation within a temperature range of -20°C to +70°C.

Feature Summary

• Fundamental mode operation for precise timing applications
• Compact 4-SMD no-lead surface mount design
• Stable frequency performance with ±20 ppm tolerance

Applications

• General purpose clock generation circuits
• Microcontroller system oscillators
• Communication interface timing sources

Procurement Notes

Verify the specific suffix 'IAR' against the manufacturer's current product lifecycle status, as availability may vary. Confirm that the 10pF load capacitance matches the target circuit design requirements. Ensure compatibility with standard reflow soldering profiles for 4-SMD packages. Cross-reference the ESR value of 60 Ohms with oscillator driver strength specifications to prevent overdriving or startup failures in the final application.

Selection Notes

Select this component when a 50 MHz fundamental frequency is required with a 10pF load capacitance constraint. The ±20 ppm stability suits general digital logic timing where high precision is not critical. The 4-SMD footprint requires adequate PCB space for 1.60mm x 1.20mm dimensions. Consider the -20°C to +70°C operating range against environmental conditions. Verify that the 60 Ohm ESR aligns with the host oscillator circuit's drive level limitations.

Part Context

This part belongs to the CTS 416 series of surface-mount crystals, designed for compact electronic assemblies. The series offers various frequency and load capacitance options within standardized SMD footprints. The 416F50022IAR specifically addresses the need for 50 MHz timing in space-constrained designs requiring moderate stability.

Replacement Considerations

Direct substitutes include parts with identical 50 MHz frequency, 10pF load capacitance, and 4-SMD footprint. Verify equivalent ESR and stability ratings. Check for pin-compatible alternatives from other manufacturers if supply constraints exist.
