8Z-38.000MAAV-T

Crystals Overview

The TXC Corporation 8Z-38.000MAAV-T is a surface-mount quartz crystal designed for precision timing applications. It operates at a fundamental frequency of 38 MHz with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 60 Ohms. The component features a frequency tolerance and stability of ±30 ppm within the operating temperature range of -20°C to +70°C. Housed in a compact 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm x 0.55 mm, it utilizes seam seal construction for environmental protection. This device is suitable for general clock generation circuits requiring high stability in a small form factor.

Crystals Feature Summary

• Seam sealed construction provides enhanced environmental protection and reliability
• Compact 4-SMD no-lead footprint enables efficient board space utilization
• Fundamental mode operation ensures stable oscillation characteristics

Crystals Applications

• General purpose clock signal generation
• Microcontroller oscillator circuits
• Digital communication interfaces

Crystals Procurement Notes

Verify that the specific order matches the exact part number 8Z-38.000MAAV-T, including suffixes, as minor variations may exist. Confirm the required load capacitance of 8 pF aligns with the host circuit design specifications. Ensure the operating temperature range of -20°C to +70°C meets the environmental requirements of the final application. Check RoHS compliance status if restricted substances are a concern for the project.

Crystals Selection Notes

Select this component when a fundamental mode quartz crystal is required rather than a packaged oscillator. The 8Z series offers a balance of size and performance for consumer electronics. Consider the 60 Ohm ESR value when designing the oscillator circuit to ensure proper startup conditions. The ±30 ppm stability is sufficient for most standard digital logic applications but may require tighter tolerances for precise serial communication protocols.

Crystals Part Context

This component belongs to the TXC 8Z series of surface mount crystals. The series is characterized by its small 2.5x2.0 mm package and seam seal technology. It serves as a passive frequency control element, distinct from active oscillators like the 8W or 8WE series which include internal circuitry. The 8Z line targets cost-sensitive applications requiring reliable timing without the complexity of active components.

Crystals Replacement Considerations

Publicly documented substitutes include CTS-Frequency Controls part number 416F38033CAR. Verify mechanical dimensions and electrical parameters such as load capacitance and ESR before substitution. Ensure the replacement part supports the same operating temperature range and mounting style.
