QT532S-32.000MEEQ-T

Overview

The QT532S-32.000MEEQ-T is a quartz crystal resonator manufactured by QST, operating at a fundamental frequency of 32 MHz. It features a frequency tolerance and stability of ±10 ppm and a load capacitance of 10 pF. The component utilizes a 4-SMD, no lead package with dimensions of 5.0 mm x 3.2 mm x 0.9 mm. Its equivalent series resistance (ESR) is specified as 40 Ohms. The device supports surface mount installation and functions within an operating temperature range of -20°C to +70°C.

Feature Summary

• Seam seal construction for environmental protection
• Fundamental mode operation for stable frequency generation
• Compact surface-mount footprint suitable for automated assembly

Applications

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

Procurement Notes

Verify the specific package variant against the datasheet, as suffixes may indicate different sealing or tolerance levels. Confirm that the 4-terminal SMD footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the manufacturer part number with official distributor catalogs to confirm current production status and availability.

Selection Notes

Select this component when a 32 MHz fundamental frequency with ±10 ppm stability is required in a compact 5x3.2 mm package. Consider the 40 Ohm ESR value for oscillator circuit design compatibility. Evaluate the -20°C to +70°C temperature range against operational conditions. Compare against similar QT532G series parts if higher stability or wider temperature ranges are needed.

Part Context

This part belongs to the QT532S series of quartz crystals from QST. The 'S' designation typically indicates a seam-sealed package type, distinguishing it from other series like QT532G which may use different sealing methods. These components are designed for general-purpose timing applications requiring reliable frequency stability in consumer and industrial electronics.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the TXC 7M-32.000MEEQ-T. While both operate at 32 MHz with 10 ppm stability, verify package dimensions and ESR values. The TXC part uses a 3.2x2.5 mm footprint, requiring mechanical re-evaluation. Always consult official datasheets for pinout and electrical characteristic comparisons before substitution.
