8Z-40.000MAAJ-T

Crystals Overview

The 8Z-40.000MAAJ-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a fundamental frequency of 40 MHz. It features a 2.5 mm x 2 mm seam seal package with four ceramic pads. The component specifies a load capacitance of 18 pF and an equivalent series resistance (ESR) of 60 Ohms. Frequency tolerance is ±30 ppm at 25°C, with stability maintained within ±30 ppm across the -20°C to +70°C temperature range.

Crystals Feature Summary

• Utilizes a compact 2.5 mm x 2 mm seam seal construction for space-constrained designs
• Provides stable oscillation via fundamental mode quartz resonator technology
• Designed for surface mount assembly using standard SMD pad configuration

Crystals Applications

• Microcontroller clock sources
• Communication interface timing circuits
• General-purpose digital system clocks

Crystals Procurement Notes

Verify the specific suffix and tolerance requirements against the official TXC datasheet before procurement. Confirm that the 18 pF load capacitance matches the target circuit design. Ensure the operating temperature range aligns with the application environment. Request the latest manufacturing documentation to confirm compliance with current RoHS standards and material specifications.

Crystals Selection Notes

Select this component when a low-profile 40 MHz reference is required for surface mount applications. The 18 pF load capacitance must match the oscillator circuit's external capacitor values. Consider the ±30 ppm stability limit for timing-sensitive designs. Evaluate the 60 Ohm ESR against the driver circuit capabilities to ensure reliable startup.

Crystals Part Context

This part belongs to the 8Z Series of quartz crystals from TXC Corporation. The series offers various frequencies in a standardized 2.5 mm x 2 mm footprint. These components are designed for general electronic applications requiring precise timing references in compact form factors.

Crystals Replacement Considerations

Cross-reference with other 40 MHz crystals in the same 2.5x2.0 package. Verify identical load capacitance (18 pF) and frequency tolerance (±30 ppm). Check compatibility with existing PCB footprints and reflow soldering profiles.
