LFXTAL020423BULK

Overview

The LFXTAL020423BULK is a surface-mount quartz crystal resonator manufactured by IQD Frequency Products. It operates at a fundamental frequency of 8 MHz with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 40 Ohms. The component features a frequency tolerance of ±20 ppm and stability of ±30 ppm. It utilizes a 4-SMD, no-lead package measuring 5.00 mm in length, 3.20 mm in width, and 4.30 mm in maximum height. The device supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Fundamental mode operation for precise frequency generation
• Surface-mount design compatible with automated assembly processes
• Wide industrial temperature range capability

Applications

• Microcontroller clock sources
• Communication interface timing
• General-purpose digital circuit synchronization

Procurement Notes

Verify the specific suffix designation against official IQD documentation to confirm packaging configuration, as bulk variants may differ from tape-and-reel options. Ensure that the selected part meets the required frequency tolerance and stability specifications for the target application environment. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and compliance with relevant environmental standards such as RoHS.

Selection Notes

Select this component when a fundamental 8 MHz crystal is required for space-constrained designs utilizing standard SMD footprints. Consider the 40 Ohm ESR value to ensure compatibility with the oscillator circuit's drive level requirements. Evaluate the ±20 ppm tolerance against system timing accuracy needs. Confirm that the 18 pF load capacitance matches the external capacitors specified in the host schematic to maintain frequency accuracy.

Part Context

This part belongs to the LFXTAL series of quartz crystals from IQD Frequency Products. It is designed for general-purpose applications requiring stable frequency references. The component is distinct from oscillators as it requires an external driver circuit. It represents a standard solution for embedded systems needing reliable timing signals within the industrial temperature range.

Replacement Considerations

Direct substitutes include other 8 MHz, 18 pF, 4-SMD crystals with comparable ESR and tolerance. Verify pinout compatibility and footprint dimensions before substitution. Check if alternative manufacturers offer components with identical electrical parameters and mechanical constraints.
