9C-26.000MEEJ-T

Crystals Overview

The TXC CORPORATION 9C-26.000MEEJ-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 26 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 the HC-49/US package, measuring 11.40 mm in length, 4.80 mm in width, and 4.10 mm in maximum height. It operates within a temperature range of -20°C to +70°C and supports base mode operation.

Crystals Feature Summary

• Standard SMD HC-49/US footprint for direct PCB compatibility
• Low ESR design ensuring stable oscillation across temperature ranges
• RoHS compliant construction for environmental safety

Crystals Applications

• Personal computer clock circuits
• Set-top box timing sources
• Display module synchronization
• Cable modem signal processing

Crystals Procurement Notes

Verify current availability status as the part may be discontinued or subject to supply constraints. Confirm RoHS3 compliance requirements against specific project regulations. Ensure the 18pF load capacitance matches the target circuit design to prevent frequency drift. Validate that the HC-49/US package dimensions fit the designated board space without mechanical interference.

Crystals Selection Notes

Select this component when a standard 26 MHz clock source is required for consumer electronics. The ±10 ppm stability suits general digital logic applications. Consider the 30 Ohm ESR limit for oscillator circuit design. Verify that the -20°C to +70°C operating range meets environmental conditions. Alternative packages like HC-49S are not directly interchangeable without layout changes.
