STDCSK4-16M

Overview

The STDCSK4-16M is a surface-mount MHz crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 16 MHz with a frequency tolerance of ±20ppm and stability of ±30ppm. The component features an 8pF load capacitance and a maximum equivalent series resistance (ESR) of 100 Ohms. It utilizes a 2-SMD, No Lead package with dimensions of 5.00mm x 3.20mm x 1.50mm. Designed for base mode operation, it supports a commercial temperature range of -10°C to +70°C and complies with RoHS standards.

Feature Summary

• Compact 2-SMD footprint suitable for space-constrained surface mount applications
• Fundamental mode operation ensures stable oscillation characteristics
• Lead-free construction compliant with environmental regulations

Applications

• General purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and digital logic circuits
• Consumer electronics requiring standard frequency stability

Procurement Notes

Verify the specific frequency tolerance and ESR requirements against the official NDK datasheet before procurement. Confirm that the 8pF load capacitance matches the host circuit design specifications. Ensure the operating temperature range of -10°C to +70°C aligns with the intended application environment. Check for any specific packaging preferences such as tape and reel quantities if applicable.

Selection Notes

Select this component when a 16 MHz fundamental frequency is required with moderate stability. The 100 Ohm ESR limit must be compatible with the oscillator circuit's drive level constraints. Consider the 2-SMD package size for PCB layout compatibility. Verify that the commercial temperature range suffices for the operational conditions compared to industrial or automotive grades.
