LFXTAL026394

Overview

The LFXTAL026394 is a surface-mount quartz crystal oscillator manufactured by IQD Frequency Products. It operates at a standard frequency of 20 MHz with a load capacitance of 16 pF. The component features a frequency tolerance of ±30 ppm and a frequency stability of ±50 ppm. It utilizes a 4-SMD, no-lead package measuring 7.0 mm in length, 5.0 mm in width, and 1.4 mm in height. The equivalent series resistance (ESR) is specified at 40 Ohms. The device supports an operating temperature range from -20°C to +70°C and is designed for SMD/SMT installation.

Feature Summary

• Hermetically sealed ceramic package with seam-sealed metal lid for environmental protection
• Surface-mount design compatible with automated assembly processes
• RoHS compliant construction supporting lead-free manufacturing standards

Applications

• Industrial data acquisition gateway clock sources
• Ethernet PHY reference clock circuits
• General-purpose microcontroller system oscillators

Procurement Notes

Verify the specific package dimensions and electrical parameters against the official datasheet before integration. Confirm that the 16 pF load capacitance matches the target circuit design requirements. Ensure the operating temperature range meets the environmental conditions of the final application. Check for any recent part number revisions or obsolescence notices from the manufacturer.

Selection Notes

Select this component when a 20 MHz reference signal is required in a compact surface-mount form factor. The hermetic sealing provides reliability advantages over non-sealed alternatives in harsh environments. Consider the 40 Ohm ESR limit to ensure proper oscillator circuit startup and stability. Evaluate the ±50 ppm stability against the system's timing accuracy requirements.

Part Context

This component belongs to the family of industrial-grade quartz crystals offered by IQD Frequency Products. It serves as a fundamental timing element for digital systems requiring precise frequency generation. The 7x5mm footprint is common in space-constrained electronic designs where reliable clock signals are critical for data integrity and synchronization.

Replacement Considerations

LFXTAL026392 is a similar 16 MHz variant from the same manufacturer. XL-1C-020.0M by Connor Winfield is a parameter-equivalent alternative with identical frequency and package dimensions.
