AX-8.000MAFK-T

Crystals Overview

The AX-8.000MAFK-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for automotive applications under the AEC-Q200 qualification standard. It operates at a fundamental frequency of 8.000 MHz with a load capacitance of 20 pF and a frequency tolerance of ±30 ppm across the operating temperature range. The device features a maximum equivalent series resistance (ESR) of 150 Ohms and supports an excitation level of 10 µW. Housed in a compact 2-SMD no-lead package measuring 5.0 mm x 3.2 mm x 1.2 mm, it ensures reliable timing performance within a temperature range of -40°C to +85°C.

Crystals Applications

• Automotive electronic control units (ECUs)
• Infotainment system clock generation
• Body control modules
• Telematics communication interfaces

Crystals Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels to ensure compliance with AEC-Q200 standards. Confirm that the specific ordering suffix matches the required load capacitance and tolerance specifications for your circuit design. Request official datasheets and material declarations to validate RoHS compliance and lead-free status prior to integration into production lines.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 8 MHz timing in space-constrained automotive PCBs. Ensure the host oscillator circuit is designed to support a 20 pF load capacitance and can limit drive power to 10 µW to prevent frequency drift. Compare ESR limits against circuit requirements to guarantee stable startup conditions within the specified -40°C to +85°C operational window.

Crystals Part Context

This part belongs to the AX series of glass-sealed crystals from TXC Corporation, specifically engineered for harsh automotive environments. The series utilizes hermetic sealing technology to protect the quartz resonator from moisture and contaminants, offering superior long-term stability compared to standard packaged crystals. It serves as a critical timing reference for microcontrollers and communication peripherals in vehicle electronics.

Crystals Replacement Considerations

Direct substitutes include other AEC-Q200 qualified 8 MHz crystals with identical 20 pF load capacitance and similar physical dimensions, such as the AA-8.000MAHI-T. Verify that alternative parts match the 150 Ohm ESR maximum and 10 µW excitation level constraints to maintain circuit compatibility without redesigning the oscillator network.
