AT-8.000MAPY-T

Crystals Overview

The AT-8.000MAPY-T is a surface-mount crystal resonator manufactured by TXC Corporation, designed for standard clock applications. It operates at a fundamental frequency of 8.000 MHz with a load capacitance specification of 12 pF. The component utilizes a 5 mm x 3.2 mm SMD package and supports frequencies up to 100 MHz within its series capabilities. It features a frequency tolerance of ±30 ppm and an operating temperature range spanning from -40°C to +85°C. The device employs a parallel resonant mode and is constructed with silver electrodes on a ceramic substrate, ensuring reliable signal generation for digital circuits.

• Compliant with AEC-Q200 automotive qualification standards
• Utilizes a compact 5 mm x 3.2 mm surface-mount footprint
• Ensures high reliability through silver electrode construction

Crystals Applications

• Automotive electronic control units (ECUs)
• Infotainment system clock references
• Body control module timing sources
• Telematics unit synchronization

Crystals Procurement Notes

Verify the specific suffix MAPY against official TXC documentation to confirm the exact load capacitance and tolerance specifications. Ensure the procurement channel provides valid traceability for AEC-Q200 certified components intended for automotive use. Confirm that the delivered parts match the required 12 pF load capacitance parameter for circuit compatibility.

Crystals Selection Notes

Select this component when an 8 MHz reference is required for automotive-grade applications demanding AEC-Q200 certification. The 12 pF load capacitance must align with the host oscillator circuit design. Consider the -40°C to +85°C temperature range suitability for under-hood or exterior vehicle environments where standard commercial grade parts may fail.

Crystals Part Context

This part belongs to the AT series of MHz crystals from TXC Corporation, which are specifically engineered for automotive electronics. The series emphasizes robustness and frequency stability under varying thermal conditions. As a standard crystal resonator rather than an active oscillator, it requires an external oscillator circuit to generate the final clock signal for the target microcontroller or processor.

Crystals Replacement Considerations

Direct substitutes must maintain the 8 MHz frequency, 12 pF load capacitance, and AEC-Q200 qualification. Verify pinout compatibility and physical dimensions (5x3.2mm) for existing PCB footprints. Cross-reference with other TXC automotive crystal series if availability is constrained.
