416F50012CDR

Overview

The CTS-Frequency Controls 416F50012CDR is a surface-mount quartz crystal resonator operating at a fundamental frequency of 50 MHz. It features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 60 Ohms. The component offers a frequency tolerance of ±10 ppm and stability of ±20 ppm. Designed for the -20°C to +70°C temperature range, it utilizes a compact 4-SMD, no-lead package with dimensions of 1.60mm x 1.20mm x 0.45mm maximum height.

Feature Summary

• Fundamental mode operation for precise timing applications
• Compact 4-SMD no-lead surface mount footprint
• Compliant with RoHS3 environmental standards

Applications

• Microcontroller clock sources
• Communication interface timing
• Embedded system oscillators

Procurement Notes

Verify the specific suffix 'CDR' against official manufacturer documentation to confirm the 18pF load capacitation specification. Ensure the selected variant matches the required PCB layout constraints for the 4-SMD package. Cross-reference the datasheet for any recent design changes or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when an 18pF load capacitance is required for the target circuit design. Compare the 60 Ohm ESR against the oscillator circuit's drive level limitations to ensure stable operation. Verify that the ±10 ppm initial tolerance meets the system's frequency accuracy requirements within the specified industrial temperature range.

Part Context

This part belongs to the CTS 416 Series of high-stability crystals. The series provides various load capacitance options, including 6pF, 8pF, 12pF, and 18pF variants, all sharing similar physical dimensions and electrical characteristics suitable for space-constrained electronic designs.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include 416F50012CAR and 416F50012CKT. Verify that alternative packages match the 4-SMD footprint and that load capacitance values align with the circuit design before substitution.
