QT49S-36.000MBBK-T

Overview

The QT49S-36.000MBBK-T is a surface-mount crystal oscillator manufactured by QST, operating at a nominal frequency of 36 MHz. It features an HC-49/US package with dimensions of 12.7x4.8x3.8 mm. The component exhibits a frequency tolerance of ±50 ppm at 25°C and a load capacitance of 20 pF. Its equivalent series resistance is specified as 80 Ohms. The device is designed for applications requiring stable frequency generation within digital circuits.

Feature Summary

Surface-mount construction utilizing HC-49/US package format
Resistance welded metal can design for environmental stability
RoHS compliant manufacturing process

Applications

Digital clock signal generation
Microcontroller system oscillators
Communication interface timing sources

Procurement Notes

Verify the specific suffix 'BBK' corresponds to the required ±50 ppm tolerance and 20 pF load capacitance configuration. Confirm that the SMD variant meets mechanical constraints compared to through-hole equivalents. Ensure compatibility with reflow soldering profiles specified in the official datasheet to maintain frequency stability and structural integrity during assembly processes.

Selection Notes

Select this component when a 36 MHz surface-mount solution is required with ±50 ppm initial tolerance. Consider the 80 Ohm ESR and 20 pF load capacitance requirements against the host circuit's oscillator design. Evaluate the HC-49/US footprint availability on the PCB layout to ensure proper placement and thermal management during operation.

Part Context

This part belongs to the QT49S family of surface-mount crystals from QST. The series offers various frequency options ranging from 3.2 MHz to 90 MHz with different tolerance codes. The 'B' in the model indicates ±50 ppm tolerance, while 'BK' denotes the specific packaging and termination style for surface-mount assembly.

Replacement Considerations

Direct substitutes include other QT49S variants with identical 36 MHz frequency but different tolerances such as QT49S-36.000MAAE-T (±30 ppm). Cross-reference with other manufacturers offering HC-49/US SMD packages at 36 MHz with matching 20 pF load capacitance and similar ESR specifications.
