9C-20.000MEEJ-T

Crystals Overview

The 9C-20.000MEEJ-T is a quartz crystal resonator manufactured by TXC Corporation, operating at a fundamental frequency of 20 MHz. It features a frequency stability and tolerance of ±10 ppm, with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 30 Ohms. The component utilizes an HC-49/US surface-mount package, measuring 11.40 mm in length, 4.80 mm in width, and 4.10 mm in maximum height. It supports base harmonic operation within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• High frequency accuracy with ±10 ppm stability
• HC-49/US surface-mount form factor
• Fundamental mode resonance operation

Crystals Applications

• Precision timing circuits requiring stable clock references

Crystals Procurement Notes

Verify the specific suffix J-T against official TXC documentation to confirm package variant and tape/reel specifications. Ensure the intended application environment remains within the specified -20°C to +70°C operational temperature range. Confirm that the 18 pF load capacitance matches the design requirements for accurate frequency performance.

Crystals Selection Notes

Select this component when high precision timing is required in space-constrained designs utilizing standard SMD footprints. The ±10 ppm tolerance offers superior stability compared to general-purpose crystals. Consider the HC-49/US size constraints and verify compatibility with automated pick-and-place equipment for manufacturing integration.
