LFXTAL072351

Overview

The LFXTAL072351 is a surface-mount quartz crystal manufactured by IQD Frequency Products, designed for automotive applications within the 12SMX AUTO-B series. It operates at a nominal frequency of 6 MHz with a load capacitance of 18 pF. The component exhibits a frequency tolerance of ±50 ppm and a total frequency stability of ±100 ppm over the operating temperature range. It features an equivalent series resistance (ESR) of 150 Ohms and utilizes a 4-SMD, no-lead package measuring 7 mm by 5 mm.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q200 standards
• Surface-mount design for automated assembly processes
• High stability performance suitable for precision timing circuits

Applications

• Automotive electronic control units (ECUs)
• Infotainment system clock generation
• Sensor interface timing references

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, such as bulk or tape and reel, as availability varies by distributor. Confirm RoHS compliance status and ensure the selected variant aligns with the intended PCB footprint dimensions. Cross-reference the manufacturer part number against authorized supplier lists to guarantee authenticity and traceability for automotive production lines.

Selection Notes

Select this component when a 6 MHz reference signal is required in space-constrained automotive designs. The 18 pF load capacitance must match the oscillator circuit requirements to ensure accurate frequency operation. Consider the 150 Ohm ESR value when designing drive level constraints to prevent overdriving the crystal element during startup and steady-state conditions.

Part Context

This device belongs to the 12SMX AUTO-B series of quartz crystals specifically engineered for harsh automotive environments. The series provides robust frequency stability across wide temperature ranges, ensuring reliable operation in vehicles. IQD Frequency Products utilizes advanced manufacturing techniques to maintain tight tolerances and low aging rates for these surface-mount components.

Replacement Considerations

Direct replacements include other 6 MHz SMD crystals from the same series with identical 18 pF load capacitance and compatible package dimensions. Verify that substitute parts meet the same AEC-Q200 qualification standards and frequency stability specifications to maintain system performance integrity.
