7A-12.000MAHK-T

Crystals Overview

The 7A-12.000MAHK-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 12 MHz with a frequency stability of ±30 ppm and a load capacitance of 20 pF. The component features an equivalent series resistance (ESR) of 80 Ohms and utilizes a 2-pad SMD package without leads. It is qualified under the AEC-Q200 automotive standard, ensuring reliability in demanding environments.

Crystals Feature Summary

• Automotive-grade qualification compliant with AEC-Q200 standards
• Glass-sealed construction for enhanced environmental protection
• Fundamental mode operation for stable frequency generation

Crystals Applications

• Automotive electronic systems requiring certified timing components
• Microcontroller clock sources in vehicle control units
• Communication modules within automotive infotainment systems

Crystals Procurement Notes

Verify that the specific part number matches the required load capacitance of 20 pF and ESR of 80 Ohms for circuit compatibility. Confirm AEC-Q200 certification status if automotive compliance is mandatory. Ensure the 2-pad SMD footprint aligns with the target PCB layout design before finalizing procurement decisions.

Crystals Selection Notes

Select this component when automotive reliability and glass-sealed durability are prioritized over smaller form factors. The 20 pF load capacitance requires matching oscillator circuit designs. Consider the 80 Ohm ESR value against other series options like AV or 7M if lower impedance is needed for specific drive level constraints.

Crystals Part Context

This component belongs to the 7A Series from TXC Corporation, which specializes in 2-pad SMD glass-sealed crystal units. Unlike the AV series which uses a 4-terminal package, the 7A series offers a distinct two-pad configuration suitable for specific mounting requirements while maintaining high-quality factor performance.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Alternative solutions may require manual verification of electrical parameters such as load capacitance, ESR, and frequency tolerance against the original specifications.
