AZ-12.000MFHE-T

Crystals Overview

The AZ-12.000MFHE-T is a quartz crystal manufactured by TXC Corporation, designed for automotive applications with AEC-Q200 certification. It operates at a fundamental frequency of 12 MHz and utilizes a seam-seal package configuration. The component features a 4-pad surface-mount footprint within a compact 2.5 mm x 2.0 mm outline. Frequency stability is specified at +/-15 ppm at 25°C and +/-30 ppm across the -40°C to +85°C operating temperature range. It employs a ceramic resonator element and requires a load capacitance of 12 pF.

Crystals Procurement Notes

Verify that the specific part number matches the required AEC-Q200 qualification status and frequency tolerance specifications. Confirm the package dimensions align with the PCB layout constraints. Ensure the supplier provides documentation confirming the ceramic seam-seal construction and load capacitance requirements. Cross-reference the manufacturer datasheet for any recent product change notices or obsolescence alerts before finalizing procurement decisions.

Crystals Selection Notes

Select this component when an automotive-grade quartz crystal with high frequency stability is required in a minimal footprint. The 12 MHz frequency suits standard communication interfaces. The AEC-Q200 certification is essential for safety-critical vehicle subsystems. Consider the 12 pF load capacitance requirement during circuit design to ensure accurate oscillator performance without additional external tuning components.

Crystals Part Context

This part belongs to the AZ series of seam-seal crystals from TXC Corporation, specifically engineered for automotive environments. It complements other automotive-certified components like the AV and 8Z series, offering a balance between size reduction and robust performance. The series supports various frequencies while maintaining consistent mechanical and electrical characteristics suitable for mass production in vehicle electronics.

Crystals Replacement Considerations

Direct substitutes include the AV-12.000MAGE-T and QT325S-12.000MDIE-T from TXC Corporation, which share similar automotive qualifications and form factors. Verify pin compatibility and load capacitance requirements when transitioning between these alternatives.
