LFXTAL057824

Overview

The LFXTAL057824 is a quartz crystal oscillator manufactured by IQD Frequency Products, belonging to the CFPX-180 series. It operates at a fundamental frequency of 27 MHz with a load capacitance of 18 pF. The component features a tolerance of 20 ppm and a frequency stability of 30 ppm. Designed for surface-mount applications, it utilizes an SMD/SMT termination style within a compact package measuring 3.4 mm in length, 2.7 mm in width, and 0.8 mm in height. The unit supports an operating temperature range from -40°C to +125°C and maintains an equivalent series resistance (ESR) of 40 Ohms.

Feature Summary

• Surface-mount quartz crystal designed for high-temperature environments up to 125°C
• Compact 3.4 mm x 2.7 mm footprint suitable for space-constrained PCB layouts
• Fundamental mode operation providing stable 27 MHz timing reference

Applications

• High-temperature industrial control systems requiring precise clock signals
• Automotive electronics operating under extended thermal conditions
• Consumer devices utilizing 27 MHz RF modulation or carrier frequencies

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as cut tape or reel options, as these affect handling procedures. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the full part number against distributor catalogs to identify available supply chain channels and lead times associated with current production cycles.

Selection Notes

Select this component when a 27 MHz fundamental frequency is required alongside a maximum operating temperature of 125°C. Ensure the circuit design accommodates the specified 18 pF load capacitance to maintain accurate frequency performance. Verify that the PCB layout supports the 3.4 mm x 2.7 mm SMD package dimensions and that the application environment does not exceed the thermal limits defined in the datasheet specifications.

Part Context

This component belongs to the CFPX-180 series of quartz crystals from IQD Frequency Products. The series focuses on small form-factor surface-mount devices capable of withstanding elevated temperatures. The LFXTAL057824 specifically addresses applications needing reliable timing at 27 MHz where standard commercial-grade crystals would fail due to thermal stress.

Replacement Considerations

Consult official IQD Frequency Products substitution guides for verified alternative part numbers. Do not assume cross-compatibility with other manufacturers' 27 MHz crystals without verifying load capacitance, ESR, and temperature range alignment.
