LFXTAL084884

Overview

The LFXTAL084884 is a quartz crystal resonator manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a nominal frequency of 32.768 kHz with a load capacitance of 7 pF and a tolerance of ±20 ppm. The component features an equivalent series resistance (ESR) of 70 kOhms and utilizes a compact 2-SMD package measuring 3.2 mm x 1.5 mm. It supports a maximum drive level of 1 µW and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Compact 2-SMD package design simplifies PCB layout and reduces manufacturing costs
• Optimized for low-power real-time clock applications requiring precise timekeeping
• High stability quartz construction ensures reliable frequency performance

Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system timing references
• Low-power portable devices and wearables
• Industrial control systems requiring accurate timebase

Procurement Notes

Verify the specific package dimensions and electrical parameters against the official IQD datasheet before integration. Confirm that the load capacitance requirements of the host circuit match the 7 pF specification. Ensure thermal operating limits are compatible with the intended application environment. Cross-reference the manufacturer part number to avoid confusion with similar variants in the LFXTAL series.

Selection Notes

Select this component when a small form factor is required for 32.768 kHz timing. The 70 kOhm ESR suits oscillator circuits designed for high-impedance inputs typical in RTC modules. Consider the ±20 ppm tolerance for general timekeeping where extreme precision is not critical. Evaluate the 1 µW drive level to prevent overdriving the crystal in low-power designs.

Part Context

This part belongs to the LFXTAL series of surface-mount crystals from IQD Frequency Products. The series offers various frequencies and packages tailored for different size constraints. The LFXTAL084884 specifically addresses the need for miniaturized components in modern electronics while maintaining standard watch crystal frequencies.

Replacement Considerations

Consult the official IQD documentation for direct cross-references or alternative part numbers within the LFXTAL family. Verify compatibility with existing PCB footprints if substituting with other 3.2mm x 1.5mm crystals from different manufacturers.
