Overview
The QT532G-48.000MAHJ-T is a quartz crystal resonator from the QT532G series, manufactured by TXC Corporation and distributed by QST. It operates at a nominal frequency of 48 MHz with a fundamental mode configuration. The component features a frequency tolerance and stability of ±30 ppm across specified temperature ranges. It has a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. The device utilizes a glass seal construction within a 2-SMD, no-lead package measuring 5.0 x 3.2 mm.
Feature Summary
- Glass seal construction for enhanced environmental stability
- Fundamental mode quartz crystal operation
- Surface-mount design with no-lead terminals
Applications
- Clock signal generation in digital circuits
- Microcontroller oscillator inputs
- Communication module timing references
Procurement Notes
Verify manufacturer part number alignment between distributor listings and official TXC documentation. Confirm package dimensions and pin configuration match the 5.0x3.2mm SMD specification. Ensure frequency tolerance requirements align with the ±30ppm rating before integration into time-sensitive designs.
Selection Notes
Select this component when a 48 MHz fundamental frequency is required with moderate stability needs. The 18pF load capacitance must match the oscillator circuit design. Consider the 50 Ohm ESR limit for driver strength compatibility. Verify operating temperature range compliance for the specific application environment.
Part Context
This part belongs to the QT532G series of surface-mount crystals. The series offers various frequency options within similar physical footprints. The 'MAHJ' suffix typically denotes specific packaging or tape-and-reel configurations. It serves as a direct replacement for other 48MHz SMD crystals with matching electrical parameters.
Replacement Considerations
Direct substitutes include other 48MHz crystals with identical 18pF load capacitance and ≤50 Ohm ESR. Verify package size compatibility (5.0x3.2mm). Check frequency stability ratings against system requirements. Cross-reference with TXC's official substitution guide for validated alternatives.
