QT252S-32.000MAAJ-T

Overview

The QT252S-32.000MAAJ-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation under the QST brand. It operates at a nominal frequency of 32 MHz with a frequency stability of ±30 ppm at 25°C and ±30 ppm over the -20°C to +70°C temperature range. The component features a 4-SMD, no-lead package with dimensions of 2.50mm x 2.00mm and a maximum seated height of 0.55mm. It utilizes a load capacitance of 18 pF and is RoHS compliant.

Feature Summary

• Seam seal construction for enhanced environmental protection
• Surface mount design suitable for automated assembly
• Lead-free and RoHS compliant manufacturing process

Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronic device oscillators

Procurement Notes

Verify the manufacturer designation as TXC Corporation when sourcing this QST-branded part. Confirm the specific suffix MAJT corresponds to the 18 pF load capacitance and ±30 ppm stability specifications. Ensure the order matches the 4-SMD no-lead package format. Check current supply status as availability may be restricted or subject to standard lead times depending on the distributor.

Selection Notes

Select this component for applications requiring a 32 MHz reference with moderate stability requirements. The 18 pF load capacitance must match the circuit design's external capacitor values. Consider the -20°C to +70°C operating range for industrial or commercial environments. Verify that the 2.5x2.0 mm footprint fits within the PCB layout constraints.

Part Context

This part belongs to the QT252S series of seam-seal crystals. Similar variants in the series include frequencies such as 24 MHz, 25 MHz, and 16 MHz, often sharing the same physical dimensions but differing in load capacitance and stability ratings. The series provides a standardized form factor for compact electronic designs.

Replacement Considerations

Direct substitutes within the same series include QT252S-32.000MDDV-T and QT252S-32.000MAAE-T, though these may differ in load capacitance (8 pF or 12 pF respectively). Verify electrical compatibility before substitution.
