416F50022IKR

Overview

The 416F50022IKR is a fundamental mode quartz crystal resonator manufactured by CTS-Frequency Controls. It operates at a nominal frequency of 50 MHz with a frequency tolerance of ±20ppm and a stability of ±20ppm. The component features an 8pF load capacitance and a maximum equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, no-lead package with dimensions of 1.60mm x 1.20mm x 0.45mm. Designed for surface-mount installation, it supports an operating temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Fundamental mode operation ensures stable oscillation characteristics for precise timing applications.
• Compact 4-SMD footprint facilitates automated surface-mount assembly in space-constrained designs.
• Wide industrial temperature rating allows reliable performance across demanding environmental conditions.

Applications

• Microcontroller clock generation circuits
• Communication interface timing references
• Digital signal processing system clocks

Procurement Notes

Verify the specific suffix 'KR' against the manufacturer's official datasheet to confirm packaging configuration and compliance status. Ensure that the selected variant matches the required load capacitance and ESR specifications for the target circuit design. Cross-reference the part number with authorized distributors to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a 50 MHz fundamental crystal with low ESR is required for high-speed digital logic. The 8pF load capacitance must match the oscillator circuit requirements to ensure accurate frequency tuning. Consider the ±20ppm stability limit when evaluating long-term drift in precision timing applications compared to higher-grade alternatives.

Part Context

This part belongs to the 416 Series of surface-mount crystals from CTS-Frequency Controls. The series offers various frequencies and packages optimized for consumer electronics and industrial equipment. The 416F50022IKR specifically addresses the need for compact, reliable timing solutions in modern PCB layouts where space efficiency is critical.

Replacement Considerations

Direct substitutes include other 50 MHz, 8pF, 4-SMD crystals from CTS such as the 416F50022IAR or 416F50022ITR, provided the packaging suffix aligns with production needs. Verify ESR and stability parameters match the original design requirements before substitution.
