7V-20.000MEIE-T

Crystals Overview

The 7V-20.000MEIE-T is a MHz quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a nominal frequency of 20 MHz with a frequency stability of ±20ppm over the temperature range of -40°C to +85°C and a tolerance of ±10ppm at 25°C. The component utilizes a glass-sealed resonator housed in a 3.2mm x 2.5mm surface-mount package with four pads. It features a load capacitance of 12pF, making it suitable for circuits requiring high-frequency accuracy and environmental robustness.

Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when placing orders. Confirm that the 4-pad SMD package matches your PCB footprint design. Ensure the supply chain source provides genuine TXC Corporation products to guarantee the specified ±10ppm tolerance and glass-seal integrity. Check RoHS compliance status if required for your manufacturing process.

Crystals Selection Notes

Select this part when a small form factor is needed alongside high precision. The 12pF load capacitance must match the oscillator circuit requirements. Consider the ±20ppm wide-temperature stability for environments subject to thermal variation. Compare against standard ceramic packages if higher shock resistance is not critical.

Crystals Part Context

This component belongs to the TXC MHz quartz crystal series, distinguished by its glass-sealed technology which offers superior long-term stability compared to standard ceramic packages. It serves as a fundamental timing element in digital systems where clock jitter and drift must be minimized. The 4-pad configuration allows for secure mounting on printed circuit boards.

Crystals Replacement Considerations

No direct substitute part numbers are confirmed in the provided documentation. When replacing, ensure the new component matches the 12pF load capacitance and 4-pad SMD dimensions. Verify that any alternative maintains the same ±10ppm/±20ppm stability ratings and operates within the -40°C to +85°C range.
