416F50012AAR

Overview

The CTS-Frequency Controls 416F50012AAR is a surface-mount quartz crystal resonator operating at a fundamental frequency of 50 MHz. It features a load capacitance of 12 pF and a frequency stability of ±10 ppm, with a tolerance of ±10 ppm. The component exhibits an equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, no-lead package measuring 1.60 mm x 1.20 mm with a maximum height of 0.45 mm. Designed for base harmonic operation, it supports a commercial temperature range of -10°C to +60°C and complies with RoHS3 standards.

Feature Summary

• Compact 4-SMD footprint suitable for space-constrained surface-mount applications
• High frequency stability of ±10 ppm for precise timing requirements
• Compliant with RoHS3 environmental regulations

Applications

• Microcontroller clock sources
• Communication module timing circuits
• Digital signal processing systems

Procurement Notes

Verify the specific suffix 'AAR' indicates tape-and-reel packaging when ordering. Confirm that the 12 pF load capacitance matches the target circuit design requirements. Ensure the ±10 ppm stability meets system jitter specifications. Check current availability as lead times may vary due to supply chain conditions. Validate compliance with RoHS3 directives for final assembly integration.

Selection Notes

Select this component when a 50 MHz fundamental frequency is required with tight ±10 ppm stability. The 12 pF load capacitance must align with the oscillator circuit's input capacitance. The 60 Ohm ESR value should be compatible with the driving amplifier's output impedance. Consider the -10°C to +60°C operating range against environmental constraints. The small 1.6x1.2 mm package is ideal for high-density PCB layouts.

Part Context

This part belongs to the CTS 416 Series of miniature surface-mount crystals. The series offers various frequencies and load capacitances in standardized 4-SMD packages. The 416F50012AAR specifically targets applications needing 50 MHz precision in a compact form factor. It shares physical dimensions with other variants in the family but differs in electrical parameters like frequency and load capacitance.

Replacement Considerations

Direct substitutes include 416F50012ALR and 416F50012AAT from CTS-Frequency Controls. These alternatives share identical electrical specifications and package dimensions. Verify that any replacement maintains the 12 pF load capacitance and 60 Ohm ESR. Ensure the replacement also meets the ±10 ppm stability requirement for functional equivalence.
