LFXTAL009709

Overview

The LFXTAL009709 is a quartz crystal resonator manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a nominal frequency of 32.768 kHz, making it suitable for real-time clock circuits. The device features a load capacitance of 7 pF and a frequency tolerance of ±20 ppm at 25°C. It utilizes the compact 3215 (3.2 x 1.5 mm) SMD package with a ceramic base and hermetically sealed metal lid. The component supports a maximum drive level of 1 μW and exhibits an equivalent series resistance (ESR) of ≤70 kΩ. It functions in fundamental mode and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Hermetically sealed construction using a seam-sealed metal lid over a ceramic base for environmental protection
• Compact 3215 surface-mount footprint optimized for space-constrained portable designs
• Low power consumption characteristics with a maximum drive level of 1 μW

Applications

• Real-time clock (RTC) circuits in wearable devices
• Portable consumer electronics requiring low power operation
• Environmental monitoring instruments

Procurement Notes

Verify the specific suffix or packaging variant required for your production line, as availability may vary between bulk and reel formats. Confirm that the 3215 package dimensions align with your PCB land pattern. Ensure the 7 pF load capacitance matches your circuit design requirements to maintain accurate timing performance.

Selection Notes

Select this component when a small form factor is critical alongside reliable timekeeping. The 3215 package offers significant area savings compared to standard 3225 crystals. Verify that the target microcontroller's RTC port can support the specified ESR and drive level constraints without requiring additional external components.

Part Context

This part belongs to the CFPX-217 series from IQD Frequency Products, which specializes in miniature surface-mount crystals. The series is engineered for high reliability in harsh environments, utilizing advanced sealing techniques. It complements IQD's broader portfolio of frequency control solutions used in automotive, industrial, and medical sectors.

Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 3215 package, and 7 pF load capacitance. Cross-reference with other manufacturers offering hermetically sealed 3215 crystals to ensure pin compatibility and thermal stability meet the original design specifications.
