9C-36.000MAAE-T

Crystals Overview

The TXC Corporation 9C-36.000MAAE-T is a surface-mount MHz quartz crystal designed for commercial applications. It operates at a nominal frequency of 36.0000 MHz with a load capacitance of 12 pF. The component exhibits a frequency tolerance and stability of ±30 ppm at 25°C, maintaining ±30 ppm over the operating temperature range of -20°C to +70°C. Housed in an HC-49/US package measuring 11.40 mm x 4.80 mm with a maximum height of 4.10 mm, it supports base harmonic operation. The unit complies with RoHS standards and features a shunt capacitance of up to 7 pF.

Crystals Feature Summary

• Surface-mount construction utilizing standard HC-49/US footprint for direct PCB replacement
• Base harmonic oscillation mode ensuring reliable clock signal generation
• Compliance with RoHS environmental directives for lead-free manufacturing

Crystals Applications

• Personal computer motherboards and peripheral interfaces
• Set-top boxes and digital television receivers
• Display modules requiring precise timing synchronization
• Cable modems and broadband communication equipment

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as this variant specifies 12 pF rather than the common 18 pF standard found in other series members. Confirm that the ±30 ppm stability meets the system's timing accuracy constraints. Ensure the supplier provides documentation confirming RoHS compliance and AEC-Q200 qualification status if automotive or high-reliability criteria apply. Check for any recent product change notices affecting pinout or material composition.

Crystals Selection Notes

Select this component when a standard HC-49S form factor is required for space-constrained designs without sacrificing mounting compatibility. The 12 pF load capacitance necessitates careful matching with the oscillator circuit's stray capacitance to achieve accurate frequency output. Consider the ±30 ppm stability sufficient for general consumer electronics but potentially insufficient for high-precision networking protocols. Evaluate the -20°C to +70°C operating range against the intended environmental conditions to ensure stable performance throughout the device lifecycle.

Crystals Part Context

This part belongs to the TXC 9C series, which specializes in cost-effective, high-volume quartz crystals for consumer electronics. The series utilizes the widely adopted HC-49/US surface-mount package, facilitating easy integration into existing designs. The 9C line emphasizes production stability and broad availability across standard frequencies, making it a common choice for mass-produced devices where moderate precision and low cost are prioritized over ultra-high stability specifications.

Crystals Replacement Considerations

Direct substitutes include the 9C-36.000MEEJ-T, though it specifies an 18 pF load capacitance which may require circuit adjustment. Other compatible variants within the 9C series offer different load capacitances such as 12 pF or 18 pF; verify electrical parameters match before substitution. Generic HC-49S crystals from other manufacturers may fit mechanically but must be validated for frequency tolerance and ESR characteristics.
