QT216S-54.000MEIE-T

Overview

The QT216S-54.000MEIE-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 54 MHz with a frequency tolerance of ±10 ppm. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 50 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This device provides stable oscillation for timing circuits requiring precise frequency control.

Feature Summary

• Compact 2.0x1.6 mm surface-mount footprint suitable for space-constrained designs
• High frequency stability with ±10 ppm tolerance
• Low equivalent series resistance for efficient power operation

Applications

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

Procurement Notes

Verify the specific suffix MEIE-T against official QST documentation to ensure correct tolerance and packaging specifications. Confirm that the 12 pF load capacitance matches the target circuit design requirements. Check for RoHS compliance status in the latest datasheet before integration into production environments.

Selection Notes

Select this component when a 54 MHz reference is required with tight ±10 ppm stability. Ensure the application circuit supports a 12 pF load capacitance to maintain accuracy. The 50 Ohm ESR must be compatible with the oscillator driver strength. Consider the 4-SMD no-lead package for automated assembly processes.

Part Context

This part belongs to the QT216S series of ultra-small quartz crystals from QST. The series offers various frequencies within the same 2.0x1.6 mm package form factor. Different suffixes indicate variations in tolerance, temperature range, and packaging options. This specific model targets high-density PCB layouts requiring reliable timing references.

Replacement Considerations

Direct substitutes include other 54 MHz crystals with identical 2.0x1.6 mm SMD packages, ±10 ppm tolerance, and 12 pF load capacitance. Verify pin compatibility and electrical parameters such as ESR and drive level sensitivity before cross-referencing with alternative manufacturers.
