7M-20.000MEEJ-T

Crystals Overview

The 7M-20.000MEEJ-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a nominal frequency of 20 MHz. It utilizes a seam seal package with dimensions of 3.20 mm x 2.50 mm and a maximum height of 0.80 mm. The component supports fundamental mode operation with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 60 Ohms. Frequency stability and tolerance are specified at ±30 ppm across a commercial temperature range of -40°C to +85°C.

Crystals Feature Summary

• Seam sealed construction for environmental protection
• Surface mount design in compact 3.2x2.5 mm footprint
• Fundamental mode quartz resonance

Crystals Applications

• General purpose clock generation in consumer electronics
• Microcontroller system timing references
• Industrial control circuit boards

Crystals Procurement Notes

Verify the specific suffix 'E' against the manufacturer's official Quartz Crystal Part Number Guide to confirm exact load capacitance and tolerance specifications. Ensure the selected variant matches the required ESR and temperature stability parameters for the target application environment before finalizing procurement.

Crystals Selection Notes

Select this component when a standard 20 MHz reference is required in a small surface-mount form factor. Consider the ±30 ppm stability and 60 Ohm ESR limits relative to the host circuit's oscillator requirements. Confirm that the commercial temperature range meets the operational needs of the end product.
