AA-12.000MAHE-T

Crystals Overview

The AA-12.000MAHE-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 load capacitance of 12 pF. The component exhibits a frequency stability and tolerance of ±30 ppm across the operating temperature range of -40°C to +85°C. It features an equivalent series resistance (ESR) of 100 Ohms and utilizes a 2-SMD, no-lead package measuring 5.00 mm in length and 3.20 mm in width, with a maximum height of 1.35 mm. This device is AEC-Q200 qualified.

Crystals Feature Summary

• AEC-Q200 automotive qualification ensures reliability under rigorous automotive environmental standards.
• Seam seal construction provides robust protection against moisture ingress and mechanical stress.
• Fundamental mode operation supports stable oscillation within standard circuit configurations.

Crystals Applications

• Automotive electronic control units requiring certified timing components
• Industrial communication interfaces utilizing 12 MHz clock signals
• Consumer electronics demanding high-frequency stability in compact form factors

Crystals Procurement Notes

Verify the specific suffix 'MAHE' confirms the 12 MHz frequency, ±30 ppm tolerance, and AEC-Q200 qualification status. Ensure the ordering part number matches the required package dimensions and lead finish specifications. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential design changes affecting compatibility.

Crystals Selection Notes

Select this component when automotive-grade certification is mandatory for the application. The 12 MHz frequency suits common microcontroller clocks and serial communication baud rates. Consider the 100 Ohm ESR value for oscillator circuit design to ensure adequate drive level margins. The 5x3.2 mm package offers a balance between thermal performance and board space efficiency.

Crystals Part Context

This part belongs to the AA series of seam-seal crystals from TXC Corporation, which are specifically engineered for automotive and industrial markets. The AA series distinguishes itself through AEC-Q200 compliance, differentiating it from standard commercial-grade crystals. It serves as a reliable timing source where long-term stability and environmental resilience are critical requirements.

Crystals Replacement Considerations

Direct substitutes include AA-12.000MAGE-T, which shares identical electrical parameters but may differ in packaging or specific automotive certification details. Verify that any replacement maintains the same frequency, load capacitance, ESR, and package dimensions to ensure seamless integration without PCB redesign.
