LFXTAL071257

Overview

The LFXTAL071257 is a surface-mount quartz crystal manufactured by IQD Frequency Products. It operates at a fundamental frequency of 24 MHz with a load capacitance of 10 pF. The component features a frequency tolerance of ±10 ppm and a stability of ±30 ppm across the operating temperature range. It utilizes a 4-SMD, No Lead package measuring 2.0 mm in length, 1.6 mm in width, and 0.5 mm in height. The equivalent series resistance (ESR) is specified at 80 Ohms, and the drive level is limited to 100 uW.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Compact 2.0 x 1.6 mm SMD footprint for space-constrained designs
• High frequency stability suitable for precision timing applications

Applications

• Automotive electronic systems requiring AEC-Q200 compliance
• Microcontroller clock sources
• Communication interface circuits

Procurement Notes

Verify the specific package variant and tape/reel specifications against the official IQD datasheet before procurement. Confirm that the supply chain source provides authentic components with traceable documentation. Ensure the receiving environment meets ESD protection standards during handling. Cross-reference the part number suffixes to identify any minor revisions or packaging differences that may affect assembly processes.

Selection Notes

Select this component when a 24 MHz reference signal is required with tight initial tolerance. The 10 pF load capacitance must match the oscillator circuit design parameters. Consider the 80 Ohm ESR value for impedance matching requirements. The wide operating temperature range supports harsh environmental conditions. Verify that the physical dimensions fit within the designated PCB land pattern area.

Part Context

This part belongs to the IQXC-42 AUTO series of crystals designed for automotive applications. It serves as a passive resonator element within active oscillator circuits. The series is engineered to meet stringent automotive quality and reliability standards. It replaces older through-hole variants with a modern surface-mount form factor.

Replacement Considerations

Direct substitutes include other 24 MHz AEC-Q200 crystals with identical 2.0x1.6mm footprints and 10pF load capacitance. Verify that alternative parts maintain the same 80 Ohm ESR and ±10 ppm tolerance. Check compatibility with existing PCB silkscreens and reflow profiles.
