It features a load capacitance of 8 pF and a frequency tolerance of ±20 ppm, with stability rated at ±30 ppm. The component utilizes a 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm and a maximum height of 0.45mm. It operates within a temperature range of -20°C to +70°C and has an equivalent series resistance (ESR) of 60 Ohms.

Feature Summary

• Surface-mount design in a compact 4-SMD no-lead package for automated assembly
• Fundamental mode operation providing stable 50 MHz signal generation
• RoHS compliant construction supporting environmental regulations

Applications

• Clock signal generation for microprocessors and digital logic circuits
• Timing reference for communication interfaces requiring 50 MHz stability
• Embedded systems utilizing surface-mount technology constraints

Procurement Notes

Verify the specific suffix 'CKR' against the manufacturer's current datasheet to confirm the -20°C to +70°C operating temperature range, as other suffixes in the 416 series may indicate different thermal ratings or packaging options. Ensure the ordering documentation explicitly matches the 8 pF load capacitance requirement. Cross-reference the RoHS status and MSL rating with the latest production data sheet to confirm compliance with current project specifications before finalizing procurement orders.

Selection Notes

Select this component when a 50 MHz fundamental frequency crystal is required for space-constrained designs using 1.6x1.2mm footprints. The 8 pF load capacitance must match the circuit's external capacitive requirements. Consider the -20°C to +70°C industrial temperature range suitability for the target environment. Verify that the ±20 ppm tolerance meets the system's timing accuracy needs compared to higher precision alternatives.
