416F50012CKR

Overview

The CTS-Frequency Controls 416F50012CKR is a surface-mount quartz crystal resonator operating at a fundamental frequency of 50 MHz. It features an 8 pF load capacitance and ±10 ppm initial frequency tolerance, with ±20 ppm stability over temperature. The component utilizes a 4-SMD, No Lead package measuring 1.60 mm x 1.20 mm x 0.45 mm max. It exhibits an equivalent series resistance (ESR) of 60 Ohms and operates within a -20°C to +70°C temperature range. The device complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) rating of 1.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix 'CKR' against official manufacturer documentation to confirm the 8 pF load capacitance and -20°C to +70°C temperature range. Ensure design compatibility with the specified 60 Ohm ESR and 50 MHz fundamental frequency before integration. Cross-reference datasheet revisions to confirm current availability status and packaging specifications.

Selection Notes

Select this component when an 8 pF load capacitance is required for the target circuit design. Consider the -20°C to +70°C industrial temperature range suitability for the application environment. Verify that the 60 Ohm ESR aligns with the oscillator circuit requirements. Confirm the 4-SMD 1.6x1.2 mm package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the CTS 416 Series of miniature surface-mount crystals. The series offers various load capacitances and temperature ranges differentiated by suffix codes. The 416F50012CKR specifically denotes the 50 MHz frequency, 12th digit code for 8 pF load, and CKR suffix indicating the commercial temperature grade and tape/reel packaging format.

Replacement Considerations

Official parameter-equivalent substitutes include 416F50012CAR and 416F50012CTR from CTS-Frequency Controls. These alternatives share identical electrical characteristics but differ in load capacitance or temperature range specifications. Verify exact matching of load capacitance and temperature limits before substitution.
