QT325S-36.000MAAE-T

Overview

The QT325S-36.000MAAE-T is a 36 MHz quartz crystal resonator manufactured by QST. It features a surface-mount package with dimensions of 3.2x2.5x0.7 mm and four no-lead terminals. The component operates within a temperature range of -20°C to +70°C. Key electrical specifications include a load capacitance of 12 pF, a frequency stability of ±30 ppm, and an equivalent series resistance (ESR) of 50 Ohms.

Feature Summary

• Compact 4-SMD, No Lead surface-mount design for automated assembly
• High frequency stability of ±30 ppm across the operating temperature range
• Optimized for low power consumption applications

Applications

• Microcontroller clock sources
• Communication module timing circuits
• Consumer electronics oscillators

Procurement Notes

Verify the specific suffix 'AAE' corresponds to the required ±30 ppm stability and -20°C to +70°C temperature range. Confirm that the 12 pF load capacitance matches the target circuit design requirements. Ensure the 3.2x2.5 mm footprint aligns with the PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a 36 MHz reference signal is required in space-constrained designs. The ±30 ppm tolerance suits general-purpose digital systems where high precision is not critical. Consider alternative suffixes if wider temperature ranges or tighter frequency tolerances are necessary for the specific application environment.

Part Context

This part belongs to the QT325S series of thin-film ceramic or quartz crystals from QST. The series offers various frequency options and stability grades defined by alphanumeric suffixes. This specific model represents a standard commercial-grade option suitable for mass-produced electronic devices requiring reliable timing references.

Replacement Considerations

Direct substitutes must match the 36 MHz frequency, 12 pF load capacitance, and 3.2x2.5 mm package. Verify ESR compatibility at 50 Ohms. Cross-reference other manufacturers' 3250-sized crystals with equivalent ±30 ppm stability ratings to ensure functional interchangeability in existing oscillator circuits.
