QT216G-24.000MDDJ-T

Overview

The QT216G-24.000MDDJ-T is a surface-mount MHz crystal oscillator manufactured by QST. It operates at a nominal frequency of 24MHz and utilizes a 4-SMD, no lead package with dimensions of 2.0mm x 1.6mm x 0.6mm. The component features a load capacitance of 18pF and maintains a frequency stability of ±20ppm at 25°C and across the -20°C to +70°C temperature range. It is constructed as a glass-sealed quartz unit compliant with RoHS3 standards.

Feature Summary

• Glass-sealed quartz construction for environmental durability
• Compact 2.0x1.6mm surface-mount footprint
• Stable frequency performance within specified thermal ranges

Applications

• General purpose clock signal generation in electronic circuits
• Timing reference for microcontroller systems
• Communication module frequency sources

Procurement Notes

Verify the manufacturer designation carefully, as similar part numbers exist under TXC Corporation. Confirm the specific suffix 'MDDJ-T' matches the required 18pF load capacitance and ±20ppm stability specifications. Ensure the order reflects the QST brand origin to avoid confusion with cross-listed inventory from other suppliers.

Selection Notes

Select this component when a 24MHz clock source with ±20ppm stability is required in a minimal 2.0x1.6mm space. The 18pF load capacitance must align with the target oscillator circuit design. Consider the glass-seal technology if enhanced moisture resistance or long-term reliability is necessary for the application environment.

Part Context

This model belongs to the QT216G series of miniature crystals. The series offers various frequency options and stability grades within the same physical envelope. The MDDJ-T suffix specifically denotes the 24MHz variant with defined electrical characteristics, distinguishing it from other frequencies or tolerance levels in the lineup.

Replacement Considerations

QT216G-24.000MAAJ-T: Offers identical frequency but differs in load capacitance (6pF). QT216G-24.000MDDB-T: Provides alternative load capacitance (6pF) with similar stability. Verify circuit compatibility before substituting due to load capacitance differences.
