QT532G-26.000MAHJ-T

Overview

The QT532G-26.000MAHJ-T is a quartz crystal resonator manufactured by QST, operating at a nominal frequency of 26 MHz. It features a fundamental mode with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. The component exhibits frequency tolerance and stability specifications of ±30 ppm across specified temperature ranges. It utilizes a 2-SMD, no-lead package configuration with dimensions of 5.0 x 3.2 mm, designed for surface-mount assembly in electronic circuits requiring precise timing references.

Feature Summary

• Utilizes glass seal technology for enhanced environmental stability
• Designed for surface-mount applications with a compact footprint
• Operates in fundamental mode for precise frequency generation

Applications

• Clock signal generation in microcontroller systems
• Timing reference for communication interfaces
• Frequency control in consumer electronics devices

Procurement Notes

Verify the manufacturer designation as QST or TXC Corporation depending on supply chain sources, as both entities are associated with this part number variant. Confirm the specific suffix MAHJ-T aligns with the required tape-and-reel packaging format. Ensure compliance with RoHS directives if restricted substances are mandated for the target application environment.

Selection Notes

Select this component when a 26 MHz fundamental frequency is required with moderate stability needs. The 18 pF load capacitance must match the oscillator circuit design to ensure accurate frequency operation. Consider the 50 Ohm ESR limit to guarantee sufficient drive level compatibility within the host system's oscillator topology.

Part Context

This part belongs to the QT532G series of quartz crystals, characterized by small SMD packages and glass-seal construction. The series offers various frequency options while maintaining consistent electrical parameters such as load capacitance and ESR. It serves as a standard timing element for applications requiring reliable frequency stability in compact form factors.

Replacement Considerations

Direct substitutes include other 26 MHz crystals with identical 18 pF load capacitance and 50 Ohm ESR in compatible SMD packages. Verify that alternative parts meet the same ±30 ppm stability requirements and operate within the same temperature range specifications.
