416F50012AKR

Overview

The CTS-Frequency Controls 416F50012AKR is a surface-mount fundamental mode quartz crystal resonator operating at 50 MHz. It features an 8 pF load capacitance and ±10 ppm initial frequency tolerance with ±20 ppm stability. The component utilizes a 4-SMD, no-lead package measuring 1.60 mm x 1.20 mm x 0.45 mm maximum height. It exhibits an equivalent series resistance (ESR) of 60 Ohms and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• Fundamental mode operation within the 24 MHz to 80 MHz frequency range
• Sealed ceramic construction for environmental protection
• Compliance with RoHS3 standards and REACH regulations

Applications

• High-frequency clock signal generation in digital circuits
• Microcontroller and microprocessor system timing references
• Communication equipment oscillator circuits

Procurement Notes

Verify the specific suffix 'KR' against the manufacturer's current datasheet to confirm the exact load capacitance and temperature rating, as suffix variations often denote different electrical or environmental specifications within the same series. Ensure the design accommodates the standard 17-week lead time typically associated with this product line.

Selection Notes

Select this component when a 50 MHz fundamental resonance with low ESR is required for space-constrained designs. The 8 pF load capacitance must match the circuit's external capacitors to ensure accurate frequency oscillation. Verify that the -40°C to +85°C operating range meets the application's thermal requirements.

Part Context

This part belongs to the CTS 416 Series, which offers various seam-welded SMD crystals. The series provides multiple load capacitance options and temperature grades, allowing designers to choose specific variants like the AKR suffix for precise 8 pF loading and industrial temperature performance.

Replacement Considerations

Direct substitutes include other 416 series variants with identical 50 MHz frequency, 8 pF load capacitance, and ±10 ppm tolerance, such as 416F50012CKT or 416F50012AAT, provided they share the same package dimensions and ESR characteristics.
