STDCSK4-12M

Overview

The STDCSK4-12M is a surface-mount crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 12 MHz with a frequency tolerance of ±20ppm and stability of ±30ppm. The component features an equivalent series resistance (ESR) of 100 Ohms and a load capacitance of 8pF. It utilizes a 2-SMD, no-lead package measuring 5.00mm x 3.20mm x 1.50mm maximum height. Designed for operation between -10°C and +70°C, it belongs to the NX5032GA series.

Feature Summary

• Utilizes a compact 2-SMD no-lead package design suitable for automated surface mount assembly.
• Provides stable oscillation at 12 MHz with specified frequency tolerance and stability metrics.
• Operates in a standard commercial temperature range of -10°C to +70°C.

Applications

• Clock signal generation for microcontrollers and digital logic circuits
• Timing references for communication interfaces such as UART or SPI
• Frequency control in consumer electronic devices

Procurement Notes

Verify that the specific order matches the manufacturer part number STDCSK4-12M to ensure correct frequency and package dimensions. Confirm compatibility with the target circuit's load capacitance requirements, which are specified as 8pF for this component. Check datasheet specifications for ESR and operating temperature limits against system constraints before finalizing procurement.

Selection Notes

Select this component when a 12 MHz fundamental mode crystal is required in a 5.0x3.2mm SMD footprint. Ensure the application environment remains within the -10°C to +70°C operational range. Consider the 100 Ohm ESR value for oscillator circuit design to guarantee reliable startup. Compare against other NX5032GA variants if different frequencies or tighter tolerances are needed.

Part Context

This component is part of NDK's NX5032GA series of surface-mount crystals. NDK is a Japanese manufacturer specializing in quartz crystal components, established in 1948. The company produces various resonators and oscillators for mobile communications, automotive electronics, and IoT applications, maintaining manufacturing facilities in Japan, China, Malaysia, and the United States.

Replacement Considerations

Direct substitutes include other 12MHz crystals in the 5.0x3.2mm SMD package with similar electrical characteristics. Verify that any replacement maintains the 8pF load capacitance and 100 Ohm ESR values to ensure circuit compatibility without redesigning the oscillator network.
