9C-19.200MEEJ-T

Crystals Overview

The 9C-19.200MEEJ-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation, operating at a fundamental frequency of 19.2 MHz. It features a standard HC-49/US package with dimensions of 11.40mm x 4.80mm and a maximum height of 4.10mm. The component supports a load capacitance of 18pF and offers a frequency tolerance and stability of ±10ppm at 25°C. It operates within a temperature range of -20°C to +70°C and has an equivalent series resistance (ESR) of 30 Ohms. This device is RoHS3 compliant and classified under ECCN EAR99.

Crystals Feature Summary

• Standard HC-49/US surface mount package design for direct PCB footprint compatibility
• Fundamental mode operation ensuring stable oscillation at 19.2 MHz
• Compliant with RoHS3 environmental standards for lead-free manufacturing

Crystals Applications

• Personal computer clock circuits
• Set-top box timing references
• Display module synchronization

Crystals Procurement Notes

Verify current availability status as the product may be discontinued or subject to supply constraints. Confirm that the HC-49/US package dimensions match the target PCB layout. Ensure the 18pF load capacitance aligns with the oscillator circuit requirements. Check for RoHS3 compliance documentation if required for specific regulatory markets.

Crystals Selection Notes

Select this component when a standard 19.2 MHz reference is needed in a compact SMD form factor. The HC-49/US package allows for easy replacement of through-hole crystals without significant PCB redesign. Consider the ±10ppm stability sufficient for general consumer electronics where high precision is not critical. Verify that the -20°C to +70°C operating range meets the application's environmental conditions.

Crystals Part Context

This part belongs to the 9C series of quartz crystals from TXC Corporation, which are designed for cost-effective mass production in consumer electronics. The series is known for providing reliable performance in common frequency applications like PCs and cable modems. The 9C-19.200MEEJ-T specifically targets the widely used 19.2 MHz frequency point in a surface-mount configuration.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/US crystals with identical 19.2 MHz frequency, 18pF load capacitance, and ±10ppm tolerance. Ensure the replacement maintains the same ESR characteristics and operating temperature range to guarantee circuit reliability.
