7A-16.000MAAE-T

Crystals Overview

The TXC Corporation 7A-16.000MAAE-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 16 MHz. It features a load capacitance of 12 pF and a frequency tolerance of ±30 ppm. The component exhibits an equivalent series resistance (ESR) of 50 Ohms and is housed in a compact 2-SMD, No Lead package with dimensions of 5 mm x 3.2 mm. Designed for reliability, it supports an operating temperature range from -40°C to +85°C and utilizes SMD/SMT mounting styles for automated assembly processes.

Crystals Feature Summary

• Fundamental mode quartz crystal operation providing stable frequency generation
• Compact 2-SMD no-lead package design suitable for space-constrained PCB layouts
• Automotive-grade reliability characteristics with wide temperature stability

Crystals Applications

• Microcontroller clock sources requiring precise timing references
• Communication modules needing stable carrier frequencies
• Embedded systems utilizing surface-mount assembly techniques

Crystals Procurement Notes

Verify the specific package variant during procurement, as the 7A series includes both 2-SMD and 4-SMD configurations with differing physical dimensions. Confirm that the selected part matches the required ESR value of 50 Ohms for circuit compatibility. Ensure the manufacturer designation is strictly TXC Corporation to avoid confusion with similar model numbers from other vendors. Cross-reference the datasheet for exact mechanical tolerances before finalizing the bill of materials.

Crystals Selection Notes

Select this component when a 16 MHz fundamental frequency with ±30 ppm tolerance is required for standard digital logic applications. The 50 Ohm ESR specification suits most standard oscillator circuits without additional loading adjustments. Consider the 2-SMD form factor for boards prioritizing minimal footprint over the larger 4-SMD variants found in the same series. Validate thermal performance against the -40°C to +85°C operational range for the intended environment.

Crystals Part Context

The 7A-16.000MAAE-T belongs to the broader 7A series of quartz crystals manufactured by TXC Corporation. This series encompasses various frequencies and package types, including 4-SMD options like the 7M series. While sharing similar electrical specifications such as 16 MHz operation and 12 pF load capacitance, the 7A variant specifically offers a smaller 2-SMD footprint compared to its 4-SMD counterparts, distinguishing it within the product family.

Crystals Replacement Considerations

The 7A-16.000MAHE-T is a documented alternative within the same manufacturer's lineup, offering identical electrical parameters but utilizing a 4-SMD package instead of the 2-SMD configuration. Designers must verify mechanical clearance on the PCB layout when substituting between these two package types.
