LFXTAL025159BULK

Overview

LFXTAL025159BULK is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 32.768 kHz with a load capacitance of 12.5 pF and a frequency tolerance of ±20 ppm. The component features an equivalent series resistance (ESR) of 40 kOhms and utilizes a surface-mount cylindrical can package with radial leads, measuring 9.50 mm in length and 2.54 mm in diameter. It supports a maximum installation height of 1.80 mm and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Fundamental parallel resonance operation for stable low-frequency timing
• Surface-mount cylindrical can package design with radial termination
• Hermetically sealed construction ensuring long-term reliability

Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system oscillators
• Low-power embedded device timing references

Procurement Notes

Verify the specific packaging suffix against the manufacturer's current catalog, as bulk availability may vary. Confirm RoHS compliance status and lead material specifications prior to procurement. Ensure the selected variant matches the required surface-mount footprint and thermal characteristics for the target application environment.

Selection Notes

Select this component when a standard 32.768 kHz reference is required for space-constrained surface-mount designs. The 12.5 pF load capacitance must align with the oscillator circuit requirements. Consider the 40 kOhm ESR value for drive level sensitivity and ensure the -40°C to +85°C temperature range covers the operational extremes of the end product.

Part Context

This part belongs to the LFXTAL series of quartz crystals from IQD Frequency Products, designed for general-purpose timing applications. The BULK suffix indicates loose component packaging rather than tape-and-reel supply. It serves as a passive frequency-determining element in electronic circuits requiring precise clock generation or timekeeping functions.

Replacement Considerations

Direct substitutes include other 32.768 kHz SMD crystals with identical 12.5 pF load capacitance and similar dimensional constraints. Verify pin compatibility and mounting orientation when replacing. Cross-reference with other manufacturers' cylindrical can SMD crystals offering comparable ESR and temperature stability ratings.
