LFXTAL069944

Overview

The LFXTAL069944 is a surface-mount quartz crystal oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 12 MHz with a frequency tolerance of ±20 ppm and stability of ±30 ppm. The component features a load capacitance of 15 pF and an equivalent series resistance (ESR) of 120 Ohms. It utilizes a 4-SMD, No Lead package configuration designed for automated surface mount assembly processes.

Feature Summary

• Surface mount design compatible with standard SMT manufacturing lines
• Quartz resonator technology providing stable frequency generation
• Lead-free package construction suitable for modern PCB assembly

Applications

• General purpose clock signal generation in electronic circuits
• Microcontroller system timing references
• Digital communication interface synchronization

Procurement Notes

Verify the specific package variant and reel specifications directly with the manufacturer or authorized distributors before ordering. Confirm that the 4-SMD No Lead form factor matches your PCB footprint requirements. Ensure compatibility with your reflow soldering profile to maintain component integrity during assembly.

Selection Notes

Select this component when a 12 MHz reference is required in a compact surface-mount format. Consider the 15 pF load capacitance requirement for circuit design matching. Evaluate the 120 Ohm ESR against your oscillator circuit drive level constraints to ensure proper operation and longevity.

Part Context

This part belongs to the IQD Frequency Products quartz crystal portfolio, which includes various frequencies and packages.
