STDCSK4-20M

Overview

STDCSK4-20M is a surface-mount quartz crystal manufactured by NDK. It operates at a fundamental frequency of 20 MHz with a load capacitance of 8 pF and an equivalent series resistance of 50 Ohms. The component features a frequency tolerance of ±20 ppm and stability of ±30 ppm. It utilizes a 2-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a maximum height of 1.50 mm. The device supports base harmonic operation within a temperature range of -10°C to 70°C.

Feature Summary

• Surface-mount design in a compact 2-SMD no-lead package
• Fundamental mode operation for precise timing applications
• Epoxy-sealed terminals for environmental protection

Applications

• Clock signal generation for microcontrollers
• Timing references for communication interfaces
• Oscillator circuits in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging configuration. Confirm that the required frequency tolerance and load capacitance align with the target circuit design specifications before finalizing procurement orders.

Selection Notes

Select this component when a 20 MHz fundamental frequency is required in a small footprint. Consider the ±20 ppm tolerance and -10°C to 70°C operating range against system requirements. The 8 pF load capacitance must match the oscillator circuit design parameters for accurate frequency performance.

Part Context

This part belongs to the NX5032GA series of quartz crystals from NDK. It represents a standard surface-mount solution for general-purpose timing applications. The series offers various frequency options within the same physical package dimensions to facilitate board layout consistency across different product designs.

Replacement Considerations

NX5032GB-16MHZ-STD-CSK-5 shares the same package dimensions but differs in frequency and status.
