AA08000004

Crystals Overview

The TXC AA08000004 is a passive quartz crystal resonator with a nominal frequency of 8.000 MHz, housed in a 5.0 x 3.2 mm SMD glass-sealed package. It features a load capacitance (CL) of 16 pF and a frequency tolerance of ±30 ppm at 25°C, maintaining stability across an industrial temperature range of -40°C to +85°C. The unit exhibits a first-year aging rate of ±3 ppm and a maximum equivalent series resistance (Rr) of 150 Ω. Designed for robust performance, it supports a typical drive level of 100 µW and meets AEC-Q200 automotive qualification standards.

Crystals Feature Summary

• Glass-sealed construction provides high insulation resistance and superior electrostatic protection compared to plastic packages.
• AEC-Q200 certified reliability ensures mechanical durability against shock and vibration for demanding environments.
• Industrial-grade thermal stability maintains consistent frequency accuracy without requiring external temperature compensation.

Crystals Applications

• Industrial data acquisition systems
• Outdoor electronic equipment
• Automotive gateways
• Low-speed ADC clocking

Crystals Procurement Notes

Verify the part number suffix carefully during procurement; versions ending in 'Sx' are engineering samples and must not be used in mass production projects. Confirm that the received units correspond to version A1, which represents the official mass-production specification. Ensure compliance with RoHS directives, noting that lead content within the glass seal falls under EU directive exemptions.

Crystals Selection Notes

Select this component when designing circuits requiring a base-frequency oscillation at 8 MHz with moderate precision. The 16 pF load capacitance dictates specific matching capacitor calculations for the circuit design. Its low ESR allows compatibility with standard MCU drivers, while the specified drive level limits prevent premature crystal degradation or damage.

Crystals Part Context

This model belongs to the AA series of ultra-miniature crystals from TXC Corporation. It is distinguished by its glass-sealing technology, which enhances environmental resilience over standard plastic-encased alternatives. The component serves as a foundational timing element for digital logic and communication interfaces requiring stable clock signals.
