AM-28.224MAGQ-T

Crystals Overview

The AM-28.224MAGQ-T is a glass-sealing crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a fundamental frequency of 28.224 MHz with a load capacitance of 10 pF. The component features an initial frequency tolerance of ±30 ppm and a total frequency stability of 50 ppm. It is qualified under AEC-Q200 standards, ensuring reliability in automotive environments. The unit utilizes SMD/SMT termination and is housed in an 8 mm x 4.5 mm package. Operating temperatures range from -40°C to +150°C, with an equivalent series resistance (ESR) of 80 Ohms and an excitation level of 10 uW.

Crystals Feature Summary

• AEC-Q200 qualified for automotive reliability
• Glass-sealing construction for environmental stability
• Wide operating temperature range up to +150°C

Crystals Applications

• Automotive electronic systems
• Consumer electronics timing circuits
• General-purpose surface-mount oscillator designs

Crystals Procurement Notes

Verify the specific suffix 'GQ' against the official TXC datasheet to confirm package dimensions and terminal configuration. Ensure the required frequency tolerance of ±30 ppm aligns with system clock accuracy requirements. Confirm that the 10 pF load capacitance matches the host circuit's design specifications before finalizing procurement.

Crystals Selection Notes

Select this component when high-temperature operation up to 150°C is required alongside automotive qualification. The 8x4.5 mm footprint offers a larger mechanical profile compared to standard 3225 crystals, which may aid in thermal management or handling during assembly. Consider the 80 Ohm ESR value for impedance matching within the oscillator circuit design.

Crystals Part Context

This part belongs to the AX/AM series of quartz crystals from TXC Corporation. It is distinct from the smaller 7M series (3.2x2.5 mm) and the 7V series. The AM-28.224MAGQ-T specifically targets applications requiring robust packaging and extended temperature ranges, differentiating it from standard commercial-grade timing devices.

Crystals Replacement Considerations

The AM-28.224MDGQ-T is a documented substitute part number from TXC Corporation. Verify pin compatibility and exact dimensional tolerances when swapping between these variants.
