QT252S-32.000MEEV-T

Overview

The QT252S-32.000MEEV-T is a fundamental mode quartz crystal resonator manufactured by TXC Corporation, distributed under the QST brand. It operates at a nominal frequency of 32 MHz with a load capacitance of 8 pF. The component exhibits a frequency tolerance and stability of ±10 ppm across an operating temperature range of -20°C to +70°C. It features an equivalent series resistance (ESR) of 60 Ohms and utilizes a 4-pin surface-mount device (SMD) package without lead. The physical dimensions are specified as 2.5 mm in length, 2.0 mm in width, and a maximum seated height of 0.55 mm.

Feature Summary

• Fundamental mode quartz crystal operation for precise timing applications
• Surface-mount design with four terminals for automated assembly compatibility
• Stable frequency performance within specified industrial temperature limits

Applications

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

Procurement Notes

Verify manufacturer origin, as TXC Corporation is the producer while QST acts as a distributor. Confirm package type matches the 4-SMD no-lead specification. Ensure environmental compliance requirements align with RoHS standards. Check datasheet revisions for any updates to electrical parameters or mechanical drawings before finalizing procurement specifications.

Selection Notes

Select this component when a 32 MHz reference is required for compact SMD layouts. The 8 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR value for drive level sensitivity. Verify that the ±10 ppm stability meets system timing accuracy requirements. Compare against alternative packages if board space constraints differ from the 2.5 x 2.0 mm footprint.

Part Context

This part belongs to the QT252S series of quartz crystals. The series offers various frequencies and package sizes. The QT252S variant specifically denotes a small outline SMD package. Other members in the family may differ in frequency, capacitance, or physical dimensions while sharing similar operational principles.

Replacement Considerations

Direct substitutes include other 32 MHz crystals with identical 8 pF load capacitance and ±10 ppm stability. Compatible alternatives must fit the 2.5 x 2.0 mm SMD footprint. Verify ESR values close to 60 Ohms to ensure oscillator startup reliability. Cross-reference pin configurations to maintain circuit compatibility.
