LFXTAL050518

Overview

The LFXTAL050518 is a parallel fundamental quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 12 MHz with a load capacitance of 12 pF and a frequency tolerance of ±30 ppm. The component features an equivalent series resistance (ESR) of 90 Ohms and utilizes a 4-SMD, No Lead package measuring 5 mm x 3.2 mm. Designed for surface mount technology, it supports standard operating temperature ranges typical for commercial applications.

Feature Summary

• Surface mount design in a compact 4-SMD no-lead package
• Parallel fundamental resonance mode operation
• Hermetically sealed construction for environmental stability

Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix or packaging variant when ordering, as bulk and tape-and-reel options may exist. Confirm RoHS compliance status directly with the manufacturer or authorized distributors to ensure adherence to current environmental regulations. Cross-reference the full part number against official IQD databases to avoid confusion with similar frequency variants.

Selection Notes

Select this component when a 12 MHz reference is required in a low-profile surface mount footprint. Ensure the target circuit provides the specified 12 pF load capacitance to maintain accuracy within the ±30 ppm tolerance. Verify that the driving level remains within safe limits to prevent frequency drift or damage to the resonator element during operation.

Part Context

This part belongs to the IQD LFXTAL series of general-purpose quartz crystals. The series offers various frequencies and packages, catering to diverse electronic design needs. The LFXTAL050518 specifically addresses requirements for space-constrained designs needing reliable surface mount solutions without through-hole lead constraints.

Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 12 pF load capacitance, and 4-SMD 5x3.2mm package dimensions. Verify ESR compatibility and mounting pad layout alignment before substitution. Consult IQD documentation for approved pin-compatible alternatives if supply chain constraints require replacement.
