LFXTAL066198

Overview

The LFXTAL066198 is a quartz crystal from the IQXC-90 series manufactured by IQD Frequency Products. It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 9 pF and a frequency tolerance of ±20 ppm. The component utilizes a 2-SMD, No Lead package with dimensions of 5.0 mm x 3.2 mm x 1.4 mm. It features an equivalent series resistance (ESR) of 90 kOhms and supports a temperature range of -40°C to +85°C.

Feature Summary

• Compact surface-mount design suitable for space-constrained applications
• High stability performance with low ESR characteristics
• Industrial temperature rating for reliable operation in varied environments

Applications

• Real-time clock circuits
• Microcontroller system clocks
• Portable electronic devices

Procurement Notes

Verify the specific package variant and tolerance requirements against the official datasheet before ordering. Confirm that the 2-SMD No Lead form factor matches the PCB footprint design. Ensure the operating temperature range meets the environmental specifications of the target application. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a small footprint is required for 32.768 kHz timing applications. The 9 pF load capacitance must match the circuit design parameters. Consider the 90 kOhm ESR for oscillator circuit compatibility. The industrial temperature range ensures suitability for broader operational conditions compared to commercial grade parts.

Part Context

This part belongs to the IQXC-90 series of miniature crystals designed for IoT and smart-home applications. It represents a shift towards smaller form factors while maintaining standard timing frequencies. The series is optimized for high-volume manufacturing and cost-effective integration into consumer electronics.

Replacement Considerations

LFXTAL009678 is a documented substitute within the same manufacturer's portfolio, though it differs in package type and load capacitance.
