416F50011CKR

Overview

The CTS-Frequency Controls 416F50011CKR is a 50 MHz fundamental mode crystal resonator designed for surface-mount applications. It features an 8 pF load capacitance and a frequency stability of ±10 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 operates within a temperature range of -20°C to +70°C and has an equivalent series resistance (ESR) of 60 Ohms. The device complies with RoHS3 standards and holds a Moisture Sensitivity Level (MSL) rating of 1.

Feature Summary

• Fundamental mode operation ensures stable frequency generation at 50 MHz.
• Compact 4-SMD no-lead package facilitates automated surface-mount assembly.
• Compliant with RoHS3 environmental regulations for restricted substances.

Applications

• General-purpose clock signal generation in digital circuits
• Timing references for microcontrollers and processors
• Communication interface synchronization

Procurement Notes

Verify the specific suffix 'CKR' against official CTS documentation to confirm tape-and-reel packaging specifications. Ensure design compatibility with the 8 pF load capacitance requirement. Confirm that the operating temperature range of -20°C to +70°C meets system thermal requirements. Cross-reference the 4-SMD footprint dimensions with PCB layout constraints to ensure proper solder joint formation.

Selection Notes

Select this component when a 50 MHz fundamental frequency with ±10 ppm stability is required. The 8 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level limitations. The compact 1.60mm x 1.20mm size is suitable for space-constrained designs requiring standard SMD mounting without leaded alternatives.

Part Context

This part belongs to the CTS 416 Series of miniature crystals. The series offers various frequencies and load capacitances in small form factors. The 416F50011CKR specifically addresses the need for 50 MHz timing in compact surface-mount electronics, providing a balance between size, performance, and manufacturability for modern PCB assemblies.

Replacement Considerations

The 416F50011CTT is listed as a parameter-equivalent alternative from CTS-Frequency Controls. Verify package consistency and electrical parameters before substitution. Other family members may differ in load capacitance or frequency tolerance.
