LFXTAL069405

Overview

LFXTAL069405 is a surface-mount quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 27 MHz with a load capacitance of 18 pF and a frequency tolerance of ±20 ppm. The component features an equivalent series resistance (ESR) of 100 Ohms and utilizes the CFPX-218 package, measuring 2.6 mm in length, 2.1 mm in width, and 0.6 mm in height. It employs a four-smd, no-lead configuration suitable for automated assembly processes.

Feature Summary

• Utilizes the compact CFPX-218 sealed metal lid package design
• Supports surface-mount technology for automated PCB integration
• Provides stable oscillation at 27 MHz with specified load capacitance

Applications

• General clock signal generation in electronic circuits
• Timing reference for microcontroller systems
• Communication interface synchronization modules

Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as cut tape or reel options, as these affect handling procedures. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans to ensure supply chain alignment.

Selection Notes

Select this component when a 27 MHz timing source is required with a 18 pF load capacitance requirement. Ensure the application circuit can accommodate the 100 Ohm ESR specification. Verify that the available board space matches the 2.6 x 2.1 mm footprint dimensions of the CFPX-218 package.

Part Context

This part belongs to the LFXTAL series of quartz crystals from IQD Frequency Products. It is distinct from other series like LFSPXO (oscillators) or LFXTAL063xxx (different frequencies/packages). It represents a standard discrete crystal solution rather than a voltage-controlled or temperature-compensated oscillator.

Replacement Considerations

Direct substitutes must match the 27 MHz frequency, 18 pF load capacitance, and 2.6 x 2.1 mm SMD footprint. Verify ESR compatibility and pinout configuration if cross-referencing with other manufacturers' CFPX-style packages.
