LFXTAL009678

Overview

The LFXTAL009678 is a surface-mount quartz crystal resonator from the CFPX-217 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 32.768 kHz with a tolerance of ±20 ppm. The component features a load capacitance of 12.5 pF and an equivalent series resistance (ESR) of 70 kOhms. It utilizes a fundamental tuning fork mode for stable timing applications. The device is housed in a compact 2-SMD, leadless package measuring 3.20 mm in length, 1.50 mm in width, and 0.90 mm in maximum height. It supports a wide operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Compact 2-SMD leadless package design suitable for space-constrained surface mount applications
• Fundamental tuning fork operation mode providing stable frequency generation
• Wide industrial temperature range capability for diverse environmental conditions

Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system timing references
• Portable battery-powered devices requiring low power consumption

Procurement Notes

Verify the specific ordering suffix required for your packaging preference, such as tape and reel or cut tape, when placing orders. Confirm that the target circuit design accommodates the specified 12.5 pF load capacitance and 70 kOhm ESR values to ensure proper oscillation. Check for any recent Product Change Notifications regarding manufacturing updates or material substitutions before finalizing procurement plans.

Selection Notes

Select this component when a precise 32.768 kHz reference is needed for low-frequency timing tasks. Ensure the application board layout supports the 3.2x1.5 mm footprint dimensions. Consider the ±20 ppm tolerance if strict long-term stability is not critical. Verify that the operating environment remains within the -40°C to +85°C range to maintain specified performance characteristics throughout the product lifecycle.

Part Context

This part belongs to the CFPX-217 series of quartz crystals offered by IQD Frequency Products. The series focuses on small form-factor solutions for standard timing applications. As a fundamental mode tuning fork crystal, it differs from higher-frequency overtone crystals or oscillator modules. It serves as a passive frequency-determining element rather than an active signal generator.

Replacement Considerations

LFXTAL066198 is listed as a substitute option by the manufacturer.
