9C-27.000MBBK-T

Crystals Overview

The 9C-27.000MBBK-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation. It operates at a fundamental frequency of 27 MHz with a load capacitance of 20 pF and an equivalent series resistance (ESR) of 30 Ohms. The component provides a frequency tolerance and stability of ±50 ppm across an operating temperature range of -20°C to +70°C. Housed in the HC-49/US package, it measures 11.40 mm in length, 4.80 mm in width, and has a maximum height of 4.10 mm. This device is designed for SMD/SMT installation.

Crystals Feature Summary

• Surface mount design utilizing the HC-49/US package format
• Fundamental mode operation for precise frequency generation
• Compliant with RoHS3 specifications and lead-free manufacturing

Crystals Applications

• PC motherboards and peripheral interfaces
• Set-top boxes and digital television receivers
• LCD monitors and display drivers
• Cable modems and broadband communication equipment

Crystals Procurement Notes

Verify current availability status as this part may be discontinued or subject to limited stock. Confirm that the 20pF load capacitance matches the target circuit design requirements. Ensure the ±50ppm stability meets system timing constraints. Check for alternative sources if original manufacturer supply is unavailable due to end-of-life status.

Crystals Selection Notes

Select this component when a standard 27 MHz reference signal is required for consumer electronics. The HC-49/US form factor allows for easy integration into existing footprints. Consider the ±50ppm tolerance sufficient for general clocking applications where high precision is not critical. Verify compatibility with the host board's thermal profile during soldering processes.

Crystals Part Context

This component belongs to the 9C Series of metal can type crystals from TXC Corporation. The series is characterized by high mass production capability and low equivalent series resistance. These units are widely used in the PC, STB, LCDM, and Cable Modem industries. The 9C series offers a broad range of standard frequencies suitable for various digital logic timing needs.

Crystals Replacement Considerations

Public confirmed substitute: QT49S-27.000MBBK-T by QST. This alternative offers parameter equivalence for the 27 MHz frequency, 20pF load capacitance, and HC-49S package dimensions.
