LFXTAL026386

Overview

The LFXTAL026386 is a quartz crystal resonator manufactured by IQD Frequency Products, operating at a fundamental frequency of 14.31818 MHz. It features a frequency tolerance of ±30 ppm and a load capacitance of 16 pF. The component utilizes a 4-SMD, No Lead package with dimensions of 7.00mm x 5.00mm x 1.40mm maximum height. It exhibits an equivalent series resistance (ESR) of 60 Ohms and operates within a temperature range of -20°C to +70°C.

Feature Summary

• Fundamental mode operation for stable frequency generation
• Surface mount design compatible with automated assembly processes
• Hermetically sealed ceramic construction for environmental protection

Applications

• General purpose clock signal generation in electronic circuits
• Microcontroller and processor system timing references
• Communication interface synchronization modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging configuration and frequency tolerance specifications. Confirm that the 16pF load capacitance matches the target circuit design requirements. Check for any recent revisions to the mechanical drawing or material composition that may affect soldering profiles or long-term reliability in the intended application environment.

Selection Notes

Select this component when a standard 14.31818 MHz reference is required for digital logic timing. Ensure the application voltage and drive level remain within the crystal's specified limits to prevent frequency drift or damage. Consider the ±30 ppm tolerance relative to the system's overall timing budget. Verify that the 4-SMD footprint aligns with the PCB layout constraints and thermal management requirements of the final assembly.

Part Context

This part belongs to the 12SMX-B series of surface mount crystals from IQD Frequency Products. It serves as a passive frequency control element within broader oscillator systems. The device provides a precise reference frequency for synchronous digital systems, distinguishing it from active oscillators by requiring external amplifier circuitry to sustain oscillation.

Replacement Considerations

Direct substitutes must match the 14.31818 MHz frequency, 16pF load capacitance, and 4-SMD no-lead package dimensions. Verify ESR compatibility and temperature range alignment. Cross-reference with other manufacturers' 7.0x5.0mm SMD crystal offerings ensuring identical electrical parameters.
