LFXTAL003074BULK

Overview

The LFXTAL003074BULK is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 4 MHz with a load capacitance of 30 pF and a frequency tolerance of ±20 ppm. The unit features an equivalent series resistance (ESR) of 130 Ohms and is housed in a standard HC-49/4H through-hole package. Designed for reliable performance, it supports a maximum drive level of 500 uW and functions within an operating temperature range of -10°C to +60°C.

Feature Summary

• Fundamental oscillation mode ensures stable timing signals for digital circuits.
• HC-49/4H through-hole package facilitates easy integration into legacy and modern PCB designs.
• Compliant with RoHS3 standards for environmentally safe manufacturing.

Applications

• Microcontroller clock generation
• Communication interface timing
• Industrial control systems

Procurement Notes

Verify the specific suffix 'BULK' indicates bulk packaging rather than tape and reel when ordering. Confirm that the HC-49/4H package dimensions align with your board layout constraints. Ensure the 500 uW maximum drive level specification is compatible with your oscillator circuit design to prevent frequency drift or crystal damage during operation.

Selection Notes

Select this component when a 4 MHz fundamental frequency with 30 pF load capacitance is required for through-hole applications. The ±20 ppm tolerance suits general-purpose timing needs where high precision is not critical. Consider the HC-49/4H form factor if surface mount options are unsuitable for your assembly process or mechanical requirements.
