QT216S-25.000METY-T

Overview

The QT216S-25.000METY-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 25 MHz with a frequency tolerance of ±10 ppm. The component features a load capacitance of 7 pF and an equivalent series resistance (ESR) of 90 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This device serves as a precise frequency reference element in electronic circuits requiring stable timing signals.

Feature Summary

• Provides stable frequency generation at 25 MHz with ±10 ppm tolerance
• Compact 4-SMD no-lead surface mount package for automated assembly
• Designed for low equivalent series resistance applications

Applications

• Microcontroller clock sources
• General-purpose timing circuits
• Embedded system oscillators

Procurement Notes

Verify the specific ordering suffix METY-T against the manufacturer's official datasheet to confirm the exact load capacitance and ESR specifications. Ensure the procurement channel provides valid traceability documentation. Confirm RoHS compliance status and lead-free characteristics directly from the supplier's certified documentation prior to purchase.

Selection Notes

Select this component when a 25 MHz fundamental frequency crystal is required with a 7 pF load capacitance. The 90 Ohm ESR specification must align with the oscillator circuit design requirements. The 4-SMD no-lead package size suits high-density PCB layouts where space constraints are critical for the timing reference module.

Part Context

This part belongs to the QT216S series of surface-mount crystals from QST. The series utilizes standard quartz resonator technology optimized for SMD manufacturing processes. The model designation indicates specific electrical parameters including frequency, tolerance, and package type within the broader product line.

Replacement Considerations

Substitute parts must match the 25 MHz frequency, ±10 ppm tolerance, 7 pF load capacitance, and 90 Ohm ESR. Verify that alternative manufacturers offer compatible 4-SMD no-lead packages with identical footprint dimensions to ensure mechanical interchangeability without PCB redesign.
