STDCSW5-16M

Overview

The STDCSW5-16M is a surface-mount passive crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 16 MHz with a frequency tolerance of ±20 ppm and stability of ±30 ppm. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 80 Ohms. Designed for fundamental mode operation, it utilizes a 4-SMD, no-lead package measuring 3.20 mm in length, 2.50 mm in width, and 0.60 mm in height. The device supports a standard operating temperature range of -10°C to +70°C.

Feature Summary

• Compact 3.2x2.5 mm surface-mount footprint suitable for space-constrained designs
• Fundamental resonance mode operation for simplified circuit integration
• RoHS compliant construction supporting environmental regulatory standards

Applications

• Microcontroller reference clock generation
• General-purpose timing circuits in consumer electronics
• Industrial control system oscillators

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging configurations. Ensure the selected variant matches the required load capacitance and frequency stability specifications for the target application environment. Cross-reference ordering numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 80 Ohm ESR value dictates specific matching network requirements; designers must calculate external capacitors based on PCB stray capacitance to ensure stable oscillation. Verify that the -10°C lower temperature limit meets the operational requirements of the end-use environment.

Part Context

This part belongs to NDK's NX2520SA series, which focuses on miniaturized quartz crystals for portable devices. The series is characterized by high reliability and consistent performance across various consumer and industrial applications. NDK manufactures these components using proprietary crystal growth technologies to ensure precise frequency control and long-term stability.

Replacement Considerations

Direct substitutes within the same series include other frequencies such as STDCSW5-32M or STDCSW5-48M, provided the frequency difference is acceptable. For pin-compatible alternatives from other manufacturers, verify that the replacement part matches the 3.2x2.5mm dimensions, 8pF load capacitance, and 80 Ohm ESR characteristics.
