STDCSK4-14.31818M

Overview

The STDCSK4-14.31818M is a fundamental mode quartz crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 14.31818 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 100 Ohms. Designed for surface mount applications, it utilizes a 2-SMD, no lead package with dimensions of 5.00 mm in length, 3.20 mm in width, and a maximum height of 1.50 mm. It supports base harmonic operation within a temperature range of -10°C to 70°C.

Procurement Notes

Verify the specific package variant and manufacturing date code upon order confirmation. Ensure that the receiving environment meets the Moisture Sensitivity Level 1 requirements to prevent internal damage during storage. Confirm that the application circuit impedance matches the specified 8 pF load capacitance for optimal frequency accuracy. Check for any regional compliance documentation updates prior to final procurement authorization.

Selection Notes

Select this component when a 14.31818 MHz timing source is required in a 5.0 x 3.2 mm surface mount footprint. Consider the 100 Ohm ESR value for oscillator circuit design to ensure sufficient loop gain. Evaluate the ±20 ppm tolerance against system clock budget requirements. Compare thermal performance limits against the operational environment constraints before finalizing the bill of materials.

Part Context

This part belongs to the NX5032GA series of surface mount crystals from NDK. It shares the physical footprint and mounting characteristics with other frequencies in the same series, such as the STDCSK4-20M. The series is engineered for high reliability in standard commercial electronics applications, offering consistent electrical performance across the production batch.

Replacement Considerations

Direct substitutes include other manufacturers' 14.31818 MHz crystals in 5032 packages with matching 8 pF load capacitance. Verify that alternative parts meet the same 100 Ohm ESR specification to maintain oscillator stability. Cross-reference pinout compatibility and soldering profile requirements to ensure seamless integration without PCB redesign.
