416F50011CST

Overview

The 416F50011CST is a surface-mount MHz crystal manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 50 MHz with a load capacitance of 6 pF. The component offers a frequency tolerance and stability of ±10 ppm. It features an equivalent series resistance (ESR) of 60 Ohms and utilizes a 4-SMD, no-lead package measuring 1.60mm x 1.20mm x 0.45mm. Designed for operation between -20°C and +70°C, it complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 1.

Feature Summary

• Fundamental mode oscillation capability for precise timing applications
• Compact 4-SMD no-lead surface mount footprint for automated assembly
• RoHS3 compliant construction supporting environmentally regulated manufacturing

Applications

• Microcontroller clock sources requiring 50 MHz stability
• Digital signal processing timing references
• Communication interface synchronization circuits

Procurement Notes

Verify the specific suffix 'CST' against official CTS documentation to confirm packaging and availability status, as distributor listings may vary. Cross-reference the DigiKey part number 416F50011CST-ND for current supply chain data. Ensure the selected variant matches the required load capacitance and ESR specifications for the target circuit design before procurement.

Selection Notes

Select this component when a 50 MHz fundamental frequency crystal with ±10 ppm stability is required in a small SMD form factor. The 6 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR limit for drive level sensitivity. Verify that the -20°C to +70°C operating range meets the environmental requirements of the final application.

Part Context

This part belongs to the CTS 416 Series of surface-mount crystals. The series provides various frequencies and packages optimized for high-volume consumer and industrial electronics. The 416F50011CST specifically addresses the need for compact, stable timing solutions in space-constrained PCB layouts using standard SMT processes.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include 416F50011CTR and 416F50011CTT from CTS-Frequency Controls. These alternatives share identical electrical specifications and mechanical dimensions, allowing for direct pin-compatible replacement if the primary part is unavailable.
