QT325S-36.000MEIE-T

Overview

The QT325S-36.000MEIE-T is a quartz crystal resonator from the QT325S series manufactured by QST. It operates at a fundamental frequency of 36 MHz with a load capacitance of 12 pF and an equivalent series resistance of 50 Ohms. The component features a 4-SMD, No Lead package with dimensions of 3.2 x 2.5 x 0.7 mm. Frequency stability is specified at ±10 ppm over the temperature range of -20°C to +70°C.

Feature Summary

• Seam seal construction for enhanced environmental protection
• Low profile surface mount design suitable for space-constrained applications
• High frequency stability within specified operating temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Procurement Notes

Verify the suffix MEIE-T confirms the specific ±10 ppm stability rating between -20°C and +70°C. Ensure the 12 pF load capacitance matches the target circuit design requirements. Confirm the 4-SMD no-lead package type aligns with PCB footprint specifications before ordering.

Selection Notes

Select this component when a 36 MHz reference is required with tight tolerance. Compare against alternatives if wider temperature ranges or different load capacitances are needed. Verify compatibility with reflow soldering profiles for the seam seal package type.

Part Context

This part belongs to the QT325S series of quartz crystals. The series offers various frequency options and stability grades. The QT325S designation indicates a standard size surface mount crystal optimized for general-purpose timing applications in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other manufacturers' 36 MHz crystals with identical 3.2x2.5mm footprints and 12pF load capacitance. Ensure replacement parts maintain the same ±10 ppm stability specification for critical timing applications.
