QT532G-24.576MAAJ-T

Overview

The QT532G-24.576MAAJ-T is a quartz crystal resonator manufactured by QST, operating at a nominal frequency of 24.576 MHz. It features a frequency tolerance and stability of ±30 ppm at both 25°C and the -20°C to +70°C range. The component utilizes a 18 pF load capacitance and exhibits an equivalent series resistance (ESR) of 50 Ohms maximum. Designed for surface mount technology, it is housed in a compact 5.0 mm x 3.2 mm x 1.2 mm package with no lead construction.

Feature Summary

• Surface mount quartz crystal resonator with glass seal construction
• Compact 5.0x3.2mm footprint suitable for space-constrained designs
• Stable frequency performance across industrial temperature ranges

Applications

• Digital signal processing controller clock sources
• Motor control system timing references
• Real-time embedded system oscillators

Procurement Notes

Verify RoHS compliance status and specific manufacturing lot details upon order confirmation. Confirm that the supplier provides official datasheets matching the exact part number suffix. Ensure storage conditions align with manufacturer recommendations for moisture-sensitive devices prior to soldering.

Selection Notes

Select this component when a 24.576 MHz reference is required for SMD applications. The 18 pF load capacitance must match the oscillator circuit design specifications. Verify that the ±30 ppm stability meets the system's jitter and timing requirements within the operational temperature range.

Part Context

This part belongs to the QT532G series of quartz crystals from QST. The series offers various frequency options within the same 5.0x3.2mm package form factor. These components are designed for general-purpose timing applications requiring reliable surface mount integration.

Replacement Considerations

Direct substitutes include other manufacturers' 24.576 MHz crystals in 5.0x3.2mm packages with 18 pF load capacitance and ±30 ppm stability. Verify pin compatibility and electrical parameters before substitution.
