8Y-40.000MAHJ-T

Crystals Overview

The 8Y-40.000MAHJ-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for standard clock applications. It operates at a nominal frequency of 40 MHz and utilizes a ceramic package with a 2.0 mm x 1.6 mm footprint. The component features a load capacitance of 18 pF and an equivalent series resistance of 80 Ohms. Frequency tolerance is specified as ±30 ppm at 25°C and ±30 ppm across the operating temperature range of -40°C to +85°C.

Crystals Feature Summary

• Utilizes a seam-sealed ceramic construction for environmental stability
• Supports surface-mount technology with a compact four-pad no-lead package
• Maintains consistent frequency stability across extended industrial temperature ranges

Crystals Applications

• General-purpose digital clock signal generation
• Microcontroller system timing references
• Embedded communication interface synchronization

Crystals Procurement Notes

Verify that the specific part number matches the required frequency tolerance and load capacitance specifications for your circuit design. Confirm that the operating temperature range aligns with your application environment. Ensure compatibility with surface-mount assembly processes and check for RoHS compliance status if required by your manufacturing standards.

Crystals Selection Notes

Select this component when a small form factor is required for 40 MHz timing applications. Consider the 18 pF load capacitance requirement for oscillator circuit matching. Evaluate the ±30 ppm stability against system jitter requirements. Compare physical dimensions against available PCB real estate constraints before finalizing the design.

Crystals Part Context

This component belongs to the 8Y series of seam-seal quartz crystals from TXC Corporation. These devices are engineered for high-volume surface-mount production environments. The series offers various frequency options within a standardized 2.0x1.6 mm package, providing designers with consistent mechanical footprints while allowing flexibility in electrical specifications.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 18 pF load capacitance, and 2.0x1.6 mm package dimensions. Verify equivalent frequency stability and ESR values to ensure circuit performance parity.
