LFXTAL090958

Overview

LFXTAL090958 is a quartz crystal resonator from the IQXC-229LR series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±15 ppm. The component utilizes a fundamental oscillation mode and features a load capacitance of 5 pF. Designed for surface-mount applications, it is housed in a compact 1.6 mm x 1.0 mm package with a maximum height of 1.6 mm. The device supports standard CMOS logic interfaces and is suitable for precision timing circuits requiring low-power consumption.

Feature Summary

• Compact surface-mount design optimized for space-constrained PCB layouts
• High frequency stability with ±15 ppm tolerance for accurate timekeeping
• Low power consumption characteristics suitable for battery-operated systems

Applications

• Real-time clock (RTC) modules
• Microcontroller system clocks
• Portable electronic devices
• Wearable technology

Procurement Notes

Verify the specific package dimensions and load capacitance requirements against your circuit design before procurement. Confirm availability status as supply chain conditions may affect lead times. Ensure compatibility with your reflow soldering profile to maintain component integrity during assembly processes.

Selection Notes

Select this component when a small footprint is critical for SMD designs. The 32.768 kHz frequency is ideal for dividing down to one-second intervals in digital counters. Consider the ±15 ppm tolerance if higher precision is required for long-term drift compensation in your application environment.

Part Context

This part belongs to the IQXC-229LR series of ultra-small quartz crystals. It complements larger through-hole variants by offering similar electrical performance in a significantly reduced physical size. The series targets modern electronics where board real estate is limited but reliable timing signals are essential for system synchronization.

Replacement Considerations

Check for direct substitutes within the same IQD series or other manufacturers offering identical 1.6x1.0mm packages. Verify that alternative parts match the 5pF load capacitance and ±15ppm tolerance to ensure circuit compatibility without redesign.
