LFXTAL010193BULK

Overview

LFXTAL010193BULK is a quartz crystal resonator manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 6 pF. The component features a 4-SOJ package with a 2.29 mm pitch and exhibits a frequency tolerance of ±20 ppm. Its equivalent series resistance is specified as 50 kOhms. The device supports an operating temperature range from -40°C to +105°C, ensuring reliability in extended thermal environments.

Feature Summary

• Hermetically sealed construction utilizing glass-to-metal seals within an inert atmosphere for long-term stability
• Designed for surface-mount integration using a compact 4-SOJ package configuration
• Optimized for low-power timing applications requiring precise 32.768 kHz reference frequencies

Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system timing references
• Industrial control systems requiring extended temperature operation
• Medical instrumentation timing modules

Procurement Notes

Verify the specific suffix BULK indicates bulk packaging rather than tape-and-reel when reviewing distributor listings. Confirm the 4-SOJ package dimensions match the PCB footprint requirements. Ensure the supplier documentation explicitly states the -40°C to +105°C temperature range for this specific part number. Cross-reference the 6 pF load capacitance with the target oscillator circuit design parameters.

Selection Notes

Select this component when a surface-mount solution is required for 32.768 kHz timing. The 4-SOJ package offers a balance between size and handling ease compared to smaller SMD crystals. Consider the ±20 ppm tolerance against the system's total allowable frequency error budget. The extended temperature range makes it suitable for harsher environments than standard commercial-grade parts.

Part Context

This part belongs to the LFXTAL series of quartz crystals from IQD Frequency Products. The series includes various frequencies and packages, catering to both through-hole and surface-mount needs. IQD is a member of the Würth Elektronik eiSos group, providing frequency control solutions for global markets. This specific model targets applications needing reliable, low-frequency timing in a compact form factor.

Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 6 pF load capacitance, and 4-SOJ package. Verify that alternative manufacturers offer comparable ESR values near 50 kOhms. Ensure replacement parts support the same -40°C to +105°C operating range. Check if any ordering suffixes indicate different packaging or minor parameter variations.
