8Y-40.000MAHQ-T

Crystals Overview

The 8Y-40.000MAHQ-T is a surface-mount seam sealing quartz crystal manufactured by TXC Corporation, designed for high precision and frequency stability in compact electronic applications. Operating at a nominal frequency of 40.000 MHz, this component utilizes an SC-cut resonator housed within a small ceramic package measuring 2.0 mm x 1.6 mm x 0.5 mm. It features a load capacitance of 10 pF and a maximum series resistance of 60 Ohms. The device supports a frequency tolerance of ±30 ppm across an operating temperature range from -40°C to +85°C, ensuring reliable performance in demanding environments.

Crystals Feature Summary

• Seam sealing construction provides robust environmental protection and long-term reliability
• SC-cut crystal design ensures high frequency stability and low aging rates
• Ultra-small 2.0mm x 1.6mm SMD footprint enables efficient PCB space utilization

Crystals Applications

• Precision timing circuits requiring stable clock references
• Compact consumer electronics with strict size constraints
• Industrial control systems operating in variable temperatures

Crystals Procurement Notes

Verify the specific order code suffix against official TXC documentation to confirm exact frequency tolerance and temperature range specifications. Ensure compatibility with reflow soldering profiles suitable for seam-sealed ceramic packages. Confirm that the 10 pF load capacitance aligns with the host circuit's oscillator requirements before finalizing procurement.

Crystals Selection Notes

Select this component when a small form factor and high stability are required for 40 MHz applications. The ±30 ppm tolerance suits general-purpose timing needs, while the -40°C to +85°C range covers most commercial and industrial conditions. Consider the 60 Ohm impedance limit when designing matching networks for optimal drive level and signal integrity.

Crystals Part Context

This part belongs to the 8Y Series of surface-mount crystals from TXC Corporation. The series is characterized by its seam-sealed ceramic construction, which offers superior hermeticity compared to standard metal cans. These components are engineered for modern electronics where miniaturization and durability are critical design factors.

Crystals Replacement Considerations

Direct substitutes must match the 40.000 MHz frequency, 10 pF load capacitance, and 2.0x1.6x0.5 mm package dimensions. Verify that alternative SC-cut crystals maintain similar ±30 ppm tolerance and 60 Ohm max ESR to ensure circuit compatibility without redesign.
