QT161S-27.000MAAV-T

Overview

The QT161S-27.000MAAV-T is a surface-mount quartz crystal oscillator manufactured by QST. It operates at a nominal frequency of 27 MHz with a fundamental oscillation mode. The component features a compact 4-SMD, no-lead package measuring 1.60mm x 1.20mm. It exhibits a frequency tolerance and stability of ±30ppm at 25°C and across the -40°C to +85°C temperature range. The device requires an 8pF load capacitance for proper circuit integration.

Feature Summary

• Fundamental oscillation mode operation
• Compact 4-SMD leadless surface-mount design
• Stable frequency performance across industrial temperature ranges

Applications

• Clock signal generation in digital circuits
• Microcontroller system timing references
• Communication module frequency standards

Procurement Notes

Verify the manufacturer designation as QST rather than TXC, as some listings may contain conflicting data. Confirm the specific suffix AAV corresponds to the ±30ppm stability specification. Ensure the 8pF load capacitance requirement matches the target application circuit design before procurement.

Selection Notes

Select this component when a small footprint is required for 27 MHz applications. The ±30ppm stability suits general-purpose timing needs. Verify that the 4-SMD package aligns with PCB layout constraints. Consider thermal requirements if operating near the upper temperature limit.

Part Context

This part belongs to the QT161S series of miniature quartz crystals. The series offers various frequencies within a standardized 1.6x1.2mm package. It serves as a cost-effective timing solution for consumer electronics and portable devices requiring precise clock signals.

Replacement Considerations

Direct substitutes include other 27MHz crystals in identical 1.6x1.2mm packages with comparable ±30ppm stability. Verify load capacitance compatibility when cross-referencing with alternative manufacturers.
