LFXTAL003186B

Overview

The LFXTAL003186B is a quartz crystal resonator manufactured by IQD Frequency Products, belonging to the HC49-2 series. It operates at a fundamental frequency of 20 MHz with a frequency stability and tolerance of ±50 ppm. The component features a load capacitance of 20 pF and an equivalent series resistance (ESR) typical for this package type. Designed for through-hole mounting, it utilizes the standard HC49-2 case configuration. The device supports operation within a temperature range of -10°C to +60°C, providing reliable timing performance for general electronic applications requiring precise clock signals.

Feature Summary

• Fundamental mode quartz crystal operation
• Through-hole HC49-2 package construction
• Standard 20 pF load capacitance specification

Applications

• General purpose timing circuits
• Microcontroller clock sources
• Consumer electronics devices

Procurement Notes

Verify the exact operating temperature range and frequency tolerance against specific design requirements before integration. Confirm that the HC49-2 through-hole footprint matches the target PCB layout constraints. Ensure supply chain documentation aligns with current manufacturing standards for this legacy part number.

Selection Notes

Select this component when a standard through-hole crystal is required for 20 MHz applications. Consider the ±50 ppm stability limit against system timing budgets. Evaluate the HC49-2 mechanical dimensions against available board space compared to surface-mount alternatives.

Part Context

This part belongs to IQD's extensive portfolio of quartz crystals, leveraging over 40 years of manufacturing expertise in frequency control. The HC49-2 series represents a traditional form factor widely used in established designs, offering a balance of performance and ease of manual or automated assembly for non-miniaturized products.

Replacement Considerations

Direct substitutes include other manufacturers' HC49-2 packages rated for 20 MHz with similar electrical characteristics. Verify compatibility regarding pin spacing and height specifications to ensure mechanical fit without redesigning the mounting holes.
