FC2012SN 32.768K-C5NNA0KC0

Crystals Overview

The FC2012SN 32.768K-C5NNA0KC0 is a surface-mount crystal oscillator manufactured by Epson. It operates at a fundamental frequency of 32.768 kHz with a frequency tolerance of ±20 ppm. The component features a load capacitance of 12.5 pF and an equivalent series resistance (ESR) of 100 kΩ. It utilizes a 2-pin SMD package without leads, measuring 2.05 mm in length, 1.2 mm in width, and 0.6 mm in height. The drive level is specified at 0.1 µW, ensuring stable operation within standard timing applications.

Crystals Feature Summary

• Compact 2-SMD no-lead package design for space-constrained PCB layouts
• Fundamental mode operation providing precise 32.768 kHz timing reference
• Low drive level specification to maintain crystal longevity and stability

Crystals Applications

• Real-time clock circuits in portable electronics
• Microcontroller system timing references
• Battery-powered devices requiring low power consumption

Crystals Procurement Notes

Verify the specific suffix C5NNA0KC0 against official Epson documentation to confirm exact ESR and tolerance specifications. Ensure compatibility with existing PCB footprint dimensions of 2.05mm x 1.2mm. Confirm that the 12.5pF load capacitance matches the target circuit design requirements before procurement.

Crystals Selection Notes

Select this component when a small form factor is required for 32.768 kHz applications. The ±20 ppm tolerance suits general-purpose timing needs rather than high-precision metrology. Consider the 100 kΩ ESR value for oscillator circuit stability analysis. This part is suitable for consumer electronics where size constraints are critical.

Crystals Part Context

This model belongs to the FC2012SN series of crystals from Epson Timing. The series is characterized by its miniature 2-SMD package, designed for automated assembly processes. It serves as a standard timing element for low-frequency clock generation in embedded systems and digital watches.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 12.5 pF load capacitance, and 2-SMD no-lead package dimensions. Verify that alternative components offer comparable ESR values and drive level specifications to ensure circuit stability.
