LFXTAL055901

Overview

The LFXTAL055901 is a quartz crystal resonator manufactured by IQD Frequency Products, belonging to the CFPX-104 series. It operates at a fundamental frequency of 8 MHz with a load capacitance of 18 pF. The component features a frequency tolerance of ±20 ppm and a frequency stability of ±50 ppm. It is designed for surface mount installation in a compact 4-SMD, no-lead package measuring 5.00 mm in length, 3.20 mm in width, and 1.00 mm in maximum height. The device supports an operating temperature range from -20°C to +70°C.

Feature Summary

• Ultra-miniature surface mount design with a sealed metal lid for environmental protection
• Fundamental mode operation ensuring stable oscillation at 8 MHz
• Compact 4-SMD footprint suitable for high-density PCB layouts

Applications

• General purpose clock generation for microcontrollers
• Timing references in consumer electronic devices
• Industrial control system oscillators

Procurement Notes

Verify the specific operating temperature grade required for the application, as datasheet references indicate a minimum temperature of -20°C for this configuration. Confirm that the 18 pF load capacitance matches the host circuit requirements to ensure accurate frequency performance. Check current availability status directly with authorized distributors, as stock levels for specific reel or bulk packaging may vary.

Selection Notes

Select the LFXTAL055901 when a small form factor is critical for the design. The 8 MHz frequency is suitable for standard processing speeds. Ensure the application environment remains within the specified thermal limits. Consider the ESR specifications if driving capability is limited in the oscillator circuit. This component is appropriate where space constraints outweigh the need for extended industrial temperature ranges.

Part Context
