LFXTAL072543

Overview

LFXTAL072543 is a 27 MHz quartz crystal resonator manufactured by IQD Frequency Products. It features a 10 pF load capacitance and ±15 ppm initial frequency tolerance with ±20 ppm total stability. The device operates in fundamental mode with a maximum equivalent series resistance of 100 Ohms and a drive level of 500 µW. It utilizes a 4-SMD, no-lead surface-mount package measuring 2.50 mm x 2.00 mm x 0.60 mm. The component supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Surface-mount design in a compact 4-SMD no-lead package
• High-temperature operation capability up to 125°C
• Fundamental resonance mode for stable frequency generation

Applications

• Automotive electronics systems
• Industrial control equipment
• Consumer electronic devices

Procurement Notes

Verify the specific ordering suffix to confirm packaging format, as bulk and tape-and-reel options exist. Ensure the selected variant matches the required load capacitance and frequency tolerance specifications for the target circuit design. Confirm RoHS compliance status if environmental regulations apply to the manufacturing process.

Selection Notes

Select this component when a 27 MHz reference signal is required in space-constrained surface-mount layouts. The wide temperature range makes it suitable for demanding environments where standard commercial-grade crystals may fail. Verify that the circuit drive level remains within the 500 µW limit to prevent frequency drift or damage.

Part Context

This part belongs to the CFPX-218 AUTO series of automotive-grade quartz crystals. The series is designed to meet the rigorous reliability standards required for automotive applications. IQD Frequency Products manufactures these components to provide precise timing solutions for modern electronic systems requiring high stability.

Replacement Considerations

Check for direct substitutes within the same CFPX-218 family that match the 27 MHz frequency and 10 pF load capacitance. Ensure any replacement maintains the 4-SMD no-lead footprint and 2.50mm x 2.00mm dimensions to fit existing PCB layouts.
