416F50012ILR

Overview

The 416F50012ILR is a fundamental mode quartz crystal resonator manufactured by CTS-Frequency Controls. It operates at a nominal frequency of 50 MHz with a load capacitance of 12 pF. The component features a frequency tolerance of ±10 ppm and a frequency stability of ±20 ppm. It utilizes a 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm x 0.45mm. The equivalent series resistance (ESR) is specified as 60 Ohms. The device supports base harmonic operation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Fundamental mode quartz crystal resonator for precise timing applications
• Compact surface-mount design suitable for automated assembly processes
• Compliant with RoHS3 standards for environmental safety

Applications

• High-frequency clock signal generation in digital circuits
• Timing references for microcontrollers and processors
• Communication equipment requiring stable carrier frequencies

Procurement Notes

Verify the specific suffix 'ILR' corresponds to the tape-and-reel packaging configuration required for your production line. Confirm that the 12pF load capacitance matches the oscillator circuit design specifications. Ensure the ±10 ppm initial tolerance meets the system's frequency accuracy requirements. Check that the operating temperature range covers the intended environmental conditions.

Selection Notes

Select this component when a 50 MHz fundamental frequency is required with tight initial tolerance. The 12pF load capacitance must align with the host oscillator's design. Consider the 60 Ohm ESR value for drive level sensitivity. The wide industrial temperature range makes it suitable for demanding environments compared to commercial 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 high-volume manufacturing. The 416F50012ILR specifically targets applications needing 50 MHz stability in a small footprint. It complements other variants in the lineup differing only in frequency or tolerance parameters.

Replacement Considerations

The 416F50012IAR is an available alternative from the same manufacturer. Verify if the 'A' suffix indicates a different packaging type or lot code while maintaining identical electrical performance. Cross-reference with other distributors to ensure compatibility with existing inventory management systems.
