QT161S-32.000MAAQ-T

Overview

The QT161S-32.000MAAQ-T is a quartz crystal oscillator manufactured by QST, operating at a nominal frequency of 32 MHz. It features a 4-SMD, No Lead package with dimensions of 1.6 x 1.2 mm. The component exhibits a frequency tolerance of ±30 ppm at both 25°C and the -20°C to 70°C range. It has a load capacitance of 10 pF and an equivalent series resistance (ESR) of 80 Ohms.

Feature Summary

• Seam seal construction for enhanced stability
• Compact surface-mount footprint suitable for space-constrained designs
• Ceramic base material for thermal resilience

Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronics signal processing

Procurement Notes

Verify the manufacturer designation on the official datasheet, as the part number may appear under QST or TXC Corporation in various catalogs. Confirm the specific suffix 'MAAQ' corresponds to the required 10pF load capacitance and ±30ppm tolerance specifications before integration. Ensure the 4-SMD no-lead package matches the PCB footprint requirements.

Selection Notes

Select this component when a small form factor is critical alongside moderate frequency stability requirements. The 80 Ohm ESR value should be compatible with the driving circuit's oscillation conditions. Consider the -20°C to 70°C operating temperature range against the environmental constraints of the final application.

Part Context

This part belongs to the QT161S series of seam-seal crystals. These components are designed for high-volume surface-mount assembly processes. The series offers various frequency options and tolerance grades, providing flexibility for different timing accuracy needs within compact electronic devices.

Replacement Considerations

The QT161S-32.000MEEQ-T from TXC Corporation is a similar variant but specifies ±10ppm tolerance and 10pF load capacitance. Verify if the tighter tolerance requirement aligns with the design specifications before substitution.
