830003329B

Crystals Overview

The Würth Elektronik part number 830003329B is a quartz crystal oscillator operating at a fundamental frequency of 7.3728 MHz. It utilizes the HC-49/U through-hole package, measuring 11.05 mm in length and 4.65 mm in width. The component features a load capacitance of 30 pF and an equivalent series resistance (ESR) of 50 Ohms. Frequency tolerance is specified at ±20 ppm, while frequency stability is rated at ±50 ppm. These parameters define its electrical behavior for precision timing applications.

Crystals Feature Summary

• Provides stable oscillation at 7.3728 MHz with defined tolerance and stability margins
• Utilizes HC-49/U through-hole packaging for standard board mounting
• Designed for precision timing circuits requiring specific load capacitance

Crystals Applications

• Precision timing circuits
• Microcontroller clock sources
• Communication interface synchronization

Crystals Procurement Notes

Verify the exact datasheet version from Würth Elektronik to confirm current manufacturing status and environmental compliance declarations. Ensure that the HC-49/U package dimensions align with the target PCB footprint. Cross-reference the 30 pF load capacitance requirement with the host circuit design to guarantee accurate frequency operation. Confirm that the ±20 ppm tolerance meets the system's timing accuracy specifications before finalizing procurement.

Crystals Selection Notes

Select this component when a 7.3728 MHz fundamental frequency is required for digital logic or communication interfaces. The HC-49/U form factor suits designs needing robust through-hole mounting rather than surface-mount alternatives. Consider the 50 Ohm ESR and 30 pF load capacitance constraints during schematic design. This part is appropriate for applications where moderate frequency stability of ±50 ppm is sufficient for reliable system performance.

Crystals Part Context

This quartz crystal belongs to the WE-XTAL family produced by Würth Elektronik. It serves as a passive frequency-determining element within electronic assemblies. The HC-49/U style represents a traditional hermetically sealed metal can package widely used in industrial and consumer electronics. It functions alongside active components to establish precise clock signals for synchronous data processing.

Crystals Replacement Considerations

Direct substitutes must match the 7.3728 MHz frequency, HC-49/U package, 30 pF load capacitance, and similar electrical characteristics. Verify compatibility with existing PCB footprints and soldering profiles. Consult manufacturer cross-reference lists for approved equivalents ensuring identical performance metrics.
