LFXTAL035265

Overview

The LFXTAL035265 is a surface-mount quartz crystal resonator from the CFPX-180 series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a frequency tolerance of ±50 ppm. The component features a load capacitance of 16 pF and a maximum equivalent series resistance (ESR) of 50 Ohms. Designed for compact electronics, it utilizes a 4-SMD, no-lead package configuration.

Feature Summary

• Surface-mount construction in a compact 4-SMD no-lead package
• High-performance microcontroller application suitability
• CFPX-180 series filter kit compatibility

Applications

• Embedded systems requiring precise timing
• Microcontroller clock sources
• Compact consumer electronics

Procurement Notes

Verify the specific package dimensions and pinout against the official IQD datasheet to ensure compatibility with your PCB footprint. Confirm that the 16 pF load capacitance matches your circuit design requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the ±50 ppm frequency tolerance meets your system's jitter and stability specifications before finalizing the procurement order.

Selection Notes

Select this component when a small form factor is critical for the design. The 20 MHz frequency is suitable for general-purpose clocking needs. Consider the 50 Ohm ESR limit to ensure proper oscillator circuit startup. The SMD format facilitates automated assembly processes. Evaluate the thermal performance characteristics if the operating environment involves significant temperature variations.

Part Context

This part belongs to the CFPX-180 series, which offers high-frequency stability in a miniature package. IQD Frequency Products specializes in timing solutions for industrial and commercial markets.
