LFXTAL030819

Overview

The LFXTAL030819 is a quartz crystal resonator manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a fundamental frequency of 16 MHz with a frequency tolerance and stability of ±50 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 5.00 mm in length, 3.20 mm in width, and a maximum height of 1.00 mm. The device supports base harmonic operation and functions within a temperature range of -10°C to +60°C.

Feature Summary

• Surface-mount quartz crystal resonator with 4-SMD no-lead packaging
• Fundamental mode operation at 16 MHz with ±50 ppm stability
• Designed for standard load capacitance of 18 pF

Applications

• General purpose clock signal generation
• Microcontroller oscillator circuits
• Communication module timing references

Procurement Notes

Verify the specific suffix BULK against official IQD documentation to confirm packaging type. Ensure the operating temperature range of -10°C to +60°C meets application requirements. Confirm that the 18 pF load capacitance matches the circuit design specifications. Check for RoHS compliance details in the latest datasheet.

Selection Notes

Select this component when a 16 MHz fundamental frequency crystal is required for SMD assembly. Consider the ±50 ppm stability for general timing applications. Evaluate the 50 Ohm ESR against oscillator circuit constraints. Ensure the 4-SMD footprint fits the PCB layout. Verify temperature range suitability for the intended environment.

Part Context

This part belongs to the CFPX-104 series of quartz crystals from IQD Frequency Products. It is categorized under passive components and oscillators. The LFXTAL030819 serves as a frequency-determining element in electronic circuits requiring precise timing signals. It is distinct from oscillator modules as it requires external amplifier circuitry.

Replacement Considerations

Consult official substitution lists for compatible 16 MHz SMD crystals with matching 18 pF load capacitance and ±50 ppm stability. Verify package compatibility for 4-SMD no-lead footprints. Cross-reference electrical parameters such as ESR and drive level before replacement.
