7V-20.000MAHJ-T

Crystals Overview

The 7V-20.000MAHJ-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation, operating at a fundamental frequency of 20 MHz. It features a frequency tolerance and stability of ±30 ppm across an extended industrial temperature range of -40°C to +85°C. The component utilizes a load capacitance of 18 pF and exhibits a maximum equivalent series resistance (ESR) of 60 Ohms. Designed for compact electronic assemblies, it is housed in a standard 4-SMD, No Lead package with dimensions measuring 5.0 mm in length, 3.2 mm in width, and a maximum height of 1.2 mm.

Crystals Feature Summary

• Operates reliably within a wide industrial temperature environment
• Supports low power consumption through optimized motional impedance characteristics

Crystals Applications

• Microcontroller system clock generation
• Communication interface timing circuits
• Industrial control board oscillators

Crystals Procurement Notes

Verify the specific suffix configuration against the manufacturer's official part number guide to ensure correct load capacitance and tolerance specifications. Confirm that the intended application environment falls within the specified -40°C to +85°C operational limits. Cross-reference the 4-SMD footprint dimensions with the PCB design library to guarantee accurate mechanical fit during assembly.

Crystals Selection Notes

Select this component when a precise 20 MHz reference signal is required for digital logic synchronization. The ±30 ppm stability rating makes it suitable for general-purpose timing applications where moderate accuracy is sufficient. Ensure the circuit design provides the necessary 18 pF load capacitance to maintain the specified frequency accuracy under all operating conditions.

Crystals Part Context

This device belongs to the TXC 7V series of surface-mount crystals, which are engineered for high reliability in consumer and industrial electronics. The series offers various frequency options within standardized packages, allowing designers to maintain consistent board layouts while adjusting timing requirements. The 7V series emphasizes cost-effectiveness without compromising basic performance standards.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 18 pF load capacitance, and 4-SMD package dimensions. Verify that alternative sources meet the same ±30 ppm stability and -40°C to +85°C temperature range specifications to ensure functional equivalence.
