LFXTAL003003REEL

Overview

The LFXTAL003003REEL is a quartz crystal oscillator manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a standard frequency of 32.768 kHz with a load capacitance of 12.5 pF. The component features a tolerance of ±20 ppm and an equivalent series resistance of 50 kΩ. It supports a wide operating temperature range from -40°C to +85°C. The physical dimensions are 4 mm in length, 10.4 mm in width, and 3.4 mm in height, housed in a 91SMX package with four pins.

Feature Summary

• Surface-mount design suitable for automated assembly processes
• Wide industrial temperature range capability for diverse environmental conditions
• Standard 32.768 kHz frequency output for timing applications

Applications

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

Procurement Notes

Verify the specific reel packaging configuration against current distributor listings, as availability may vary. Confirm that the 91SMX package dimensions align with your PCB footprint requirements prior to ordering. Ensure the 50 kΩ ESR value is compatible with your circuit's drive level specifications to prevent overdriving the crystal.

Selection Notes

Select this component when a surface-mount solution is required for low-frequency timing applications. The 12.5 pF load capacitance must match the external capacitors in your circuit design. Consider the 50 kΩ ESR if driving sensitivity is a concern, as higher resistance limits maximum drive levels compared to lower ESR alternatives.
