LFXTAL010689BULK

Overview

The LFXTAL010689BULK is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 7.3728 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm. The component features a load capacitance of 30 pF and an equivalent series resistance (ESR) of 60 Ohms. Designed for surface mount applications, it utilizes a 4-SMD, no-lead package measuring 5.00 mm in length, 3.20 mm in width, and 1.00 mm in maximum height.

Feature Summary

• Fundamental oscillation mode operation
• Surface mount installation type
• Standard commercial temperature range capability

Applications

• Microcontroller clock sources
• Digital communication interfaces
• General-purpose timing circuits

Procurement Notes

Verify the specific package variant against the official datasheet to ensure compatibility with PCB footprint requirements. Confirm that the operating environment remains within the specified commercial temperature limits. Ensure circuit design accounts for the 30 pF load capacitance to maintain frequency accuracy. Validate RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a standard 7.3728 MHz reference is required for digital logic or microcontroller systems. The 4-SMD package facilitates automated assembly processes. Consider the ±30 ppm tolerance for applications requiring moderate frequency precision. Evaluate the 60 Ohm ESR against oscillator circuit drive level constraints to prevent overdriving the crystal.

Part Context

This part belongs to the IQD Frequency Products general-purpose crystal lineup. It serves as a passive frequency control element within larger electronic assemblies. The manufacturer provides supporting documentation including datasheets and CAD models for integration into design workflows. The component represents a standard solution for basic timing needs in consumer and industrial electronics.

Replacement Considerations

Cross-reference compatible parts from other manufacturers offering identical 7.3728 MHz frequency, 30 pF load capacitance, and 4-SMD dimensions. Verify pinout compatibility and mechanical footprint alignment before substitution. Ensure electrical parameters such as ESR and stability meet or exceed original requirements.
