LFXTAL009706

Overview

The LFXTAL009706 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 load capacitance of 9 pF and a frequency tolerance of ±20 ppm at 25°C. The component features an annual aging rate of ≤±3 ppm and supports fundamental mode oscillation. Designed for industrial applications, it offers a wide operating temperature range from -40°C to +85°C and a storage range of -55°C to +125°C. Key electrical parameters include a maximum equivalent series resistance (ESR) of 70 kΩ and a drive level of 1 μW. The device utilizes a hermetically sealed ceramic package measuring 3.2 mm x 1.5 mm.

Feature Summary

• Hermetically sealed ceramic construction using welded metal covers for enhanced environmental protection against moisture and contaminants.
• Optimized for low-power real-time clock circuits with minimal standby current impact on battery-operated systems.
• Stable frequency performance across extended industrial temperature ranges suitable for harsh operational environments.

Applications

• Real-time clock circuits in industrial gateways and smart meters
• Quartz wristwatches and digital timekeeping devices
• Radio transmitters requiring stable low-frequency reference signals

Procurement Notes

Verify the specific suffix or packaging variant when ordering, as availability may vary between bulk and tape-reel formats. Confirm RoHS compliance status through official documentation prior to integration. Ensure design compatibility with the 9 pF load capacitance requirement to maintain specified frequency accuracy. Check for any recent lifecycle changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component for designs requiring high reliability in extreme temperatures due to its sealed structure. The 9 pF load capacitance necessitates careful PCB layout and matching capacitor selection, typically 7-8 pF NP0 types. It is ideal for space-constrained boards where the compact 3215 footprint is required. Consider the high ESR value when designing oscillator circuits to ensure reliable startup conditions.

Part Context

This part belongs to the CFPX-217 series of surface-mount crystals from IQD Frequency Products. It is widely used in consumer and industrial electronics where precise timing is critical. The manufacturer, now part of Wurth Elektronik, provides extensive support for frequency control solutions across automotive, medical, and computing sectors.

Replacement Considerations

Direct substitutes within the same series should be checked for identical package dimensions and electrical parameters. Verify that alternative components match the 9 pF load capacitance and ±20 ppm tolerance requirements to ensure circuit compatibility without redesign.
