LFXTAL065455

Overview

The LFXTAL065455 is a fundamental parallel quartz crystal from the IQXC-25 series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 32.768 kHz with a tolerance of ±20 ppm and a stability of ±30 ppm. The component features a load capacitance of 6 pF and an equivalent series resistance (ESR) of 90 kOhms. Designed for surface-mount applications, it utilizes a 2-SMD, no-lead package. The device supports a drive level of 1 µW and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Hermetically sealed in an inert atmosphere with glass-to-metal seals on leads
• Fundamental mode operation for precise timing applications
• Surface-mount compatible design for automated assembly

Applications

• Real-time clock circuits
• Microcontroller system clocks
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific packaging configuration, such as tape and reel or bulk, prior to ordering, as availability may vary by region. Confirm that the target circuit design accommodates the 6 pF load capacitance requirement to ensure accurate frequency performance. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the selected variant matches the required operating temperature range of -40°C to +85°C for your specific application environment.

Selection Notes

Select this component when a standard 32.768 kHz reference is required for space-constrained designs. The 2-SMD no-lead package offers a compact footprint suitable for modern PCB layouts. Consider the 90 kOhm ESR value when designing the oscillator circuit to guarantee stable startup conditions. This part is appropriate for applications where moderate frequency stability of ±20 ppm is sufficient for long-term timekeeping accuracy.

Part Context

This crystal belongs to the IQXC-25 series, which provides industry-standard surface-mount solutions. IQD Frequency Products specializes in quartz crystals and oscillators for global electronics markets. The LFXTAL065455 represents a common frequency choice for digital systems requiring precise second-based timing references without the need for complex calibration.

Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 6 pF load capacitance, and 2-SMD no-lead package dimensions. Verify equivalent ESR values and drive level sensitivity to prevent frequency pulling or failure to oscillate. Cross-reference mechanical tolerances to ensure compatibility with existing pick-and-place equipment and soldering profiles.
