LFXTAL026384

Overview

LFXTAL026384 is a 12 MHz fundamental mode quartz crystal from the 12SMX-B series. It features a 4-SMD, no-lead package with dimensions of 7.00 mm x 5.00 mm and a maximum height of 1.40 mm. The component has a frequency tolerance of ±30 ppm at room temperature and a total frequency deviation of ±50 ppm across the -20°C to +70°C operating range. It utilizes a 16 pF load capacitance and exhibits an equivalent series resistance (ESR) of 60 Ohms. The unit employs a hermetically sealed metal lid construction on a ceramic base.

Feature Summary

• Hermetically sealed metal lid construction for enhanced environmental protection
• Standard surface-mount footprint compatible with automated assembly
• Fundamental resonance mode operation

Applications

• Microcontroller main clock sources
• Industrial communication bus synchronization
• General-purpose timing circuits

Procurement Notes

Verify the specific ordering suffix against official IQD Frequency Products documentation to confirm exact packaging configuration and lot traceability. Ensure the selected variant matches the required thermal stability specifications for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when a standard industrial temperature range of -20°C to +70°C is sufficient for the design requirements. The 16 pF load capacitance must align with the oscillator circuit's internal capacitive requirements to ensure accurate frequency generation. Consider the 60 Ohm ESR value when designing the drive level constraints to prevent over-driving the crystal element during operation.

Part Context

This crystal belongs to the 12SMX-B series manufactured by IQD Frequency Products, which is now part of the Würth Elektronik group. The series provides standard-sized SMD crystals suitable for general electronic applications requiring reliable frequency control without the need for specialized wide-temperature or high-stability variants found in other product lines.

Replacement Considerations

The Wurth Elektronik part number 830026384 serves as a direct equivalent for this component. Verify mechanical compatibility and electrical parameter alignment when substituting.
