STDCSK4-30M

Overview

The STDCSK4-30M is a surface-mount quartz crystal resonator manufactured by NDK. It operates at a fundamental frequency of 30 MHz with a load capacitance of 8 pF and an equivalent series resistance (ESR) 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 in length, 3.20 mm in width, and 1.50 mm in maximum height. The device supports base harmonic operation within a temperature range of -10°C to 70°C.

Feature Summary

• Compact 2-SMD surface mount design for automated assembly
• Fundamental mode oscillation capability
• Lead-free construction compatible with IR reflow processes

Applications

• Microcontroller clock sources
• Communication module timing circuits
• General-purpose electronic equipment

Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging options. Ensure the ordering code matches the required frequency stability and package dimensions. Confirm RoHS compliance status through current regulatory documentation before finalizing procurement orders.

Selection Notes

Select this component when a 30 MHz fundamental frequency is required in a compact 5.0 x 3.2 mm footprint. The 50 Ohm ESR suits standard oscillator circuits. Verify that the operating temperature range of -10°C to 70°C meets the environmental requirements of the target application board.

Part Context

This part belongs to the NX5032GA series of SMD crystals from NDK. The series focuses on providing reliable timing solutions in small form factors suitable for modern consumer electronics and industrial applications requiring stable frequency generation.

Replacement Considerations

Cross-reference with other 30 MHz 2-SMD crystals from NDK such as the STDCSK4-20M for different frequencies or the CS15191-30M if a 4-pin package is acceptable. Ensure pin compatibility and electrical parameters match before substitution.
