LFXTAL069381

Overview

LFXTAL069381 is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a load capacitance of 10 pF. The component features a tolerance and frequency stability of ±20 ppm. It utilizes a 4-SMD, no lead package with dimensions of 2.5 mm x 2.0 mm. The equivalent series resistance (ESR) is specified as 100 Ohms. The device supports surface mount installation and is designed for general electronic timing applications.

Feature Summary

• Fundamental mode quartz crystal operation
• Surface mount compatible 4-SMD no lead package
• Standard 20 MHz frequency output
• ±20 ppm frequency stability

Applications

• General purpose clock generation circuits
• Microcontroller system timing references

Procurement Notes

Verify the specific package variant and tolerance requirements against the official IQD datasheet before ordering. Confirm that the 100 Ohm ESR and 10 pF load capacitance align with the target oscillator circuit design. Ensure the 4-SMD no lead footprint matches the PCB layout specifications to guarantee proper solder joint integrity and mechanical reliability during assembly.

Selection Notes

Select this component when a 20 MHz reference with ±20 ppm stability is required in a compact surface mount form factor. The 100 Ohm ESR value must be compatible with the driving circuit's oscillation conditions. Consider the 10 pF load capacitance requirement to ensure accurate frequency tuning within the application environment without requiring external compensation components.

Part Context

This part belongs to the IQD LFXTAL series of quartz crystals, which provides various frequencies and packages for timing applications. IQD Frequency Products specializes in frequency control solutions, offering both through-hole and surface mount options.
