QT252S-32.000MEIQ-T

Overview

The QT252S-32.000MEIQ-T is a surface-mount crystal oscillator manufactured by QST Products, LLC. It operates at a nominal frequency of 32 MHz with a load capacitance of 10 pF and an equivalent series resistance of 60 Ohms. The component features a compact SMD2520-4P package measuring 2.50mm x 2.00mm. Frequency stability is rated at ±20 ppm over the operating temperature range of -40°C to +85°C, while initial frequency tolerance is specified at ±10 ppm at 25°C. The device is RoHS compliant and lead-free.

Feature Summary

• Compact SMD2520-4P surface mount package for space-constrained designs
• High frequency stability of ±20 ppm across extended industrial temperature ranges
• Low equivalent series resistance of 60 Ohms for efficient circuit integration

Applications

• Clock generation for microprocessors and microcontrollers
• Timing references in communication modules
• Digital signal processing circuits requiring precise frequency control

Procurement Notes

Verify that the ordering suffix matches the required frequency tolerance and stability specifications. Confirm the package type is SMD2520-4P and ensure the load capacitance aligns with the target circuit design. Check RoHS compliance status if environmental regulations apply. Validate the operating temperature range meets system requirements before procurement.

Selection Notes

Select this component when a 32 MHz reference is needed in a small footprint. Ensure the application requires ±10 ppm initial tolerance and ±20 ppm stability over -40°C to +85°C. Verify that the 10 pF load capacitance matches the oscillator circuit's input capacitance. Consider the 60 Ohm ESR for drive level limitations.

Part Context

This part belongs to the QT252S series of surface-mount crystals from QST. The series offers various frequencies and stability options in the 2.5x2.0mm package. The MEIQ suffix indicates specific tolerance and stability characteristics. This model provides a balance between size and performance for portable electronics.

Replacement Considerations

Direct substitutes include other 32 MHz crystals in the SMD2520-4P package with matching 10 pF load capacitance and similar ESR values. Verify that alternative parts meet the same ±10 ppm tolerance and ±20 ppm stability requirements. Ensure the replacement supports the -40°C to +85°C operating range.
