CS53A-F3050CQ18-12.288M

Crystals Overview

The CS53A-F3050CQ18-12.288M is a surface-mount crystal oscillator manufactured by Transko Electronics, Inc. It operates at a fundamental frequency of 12.288 MHz with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a tolerance of ±30 ppm and is housed in a 4-SMD, no-lead package measuring 5.00mm x 3.20mm. It is RoHS compliant and lead-free.

Crystals Feature Summary

• Surface-mount design for automated assembly
• Fundamental mode crystal operation
• Lead-free construction compliant with environmental standards

Crystals Applications

• Clock generation for microprocessors
• Timing reference for communication interfaces
• Frequency synthesis in consumer electronics

Crystals Procurement Notes

Verify the specific suffix 'TR' if tape-and-reel packaging is required, as the base part number may denote individual units. Confirm the exact ESR and load capacitance requirements match the host circuit design. Ensure the 4-SMD footprint aligns with the PCB layout specifications to prevent mounting issues during assembly.

Crystals Selection Notes

Select this component when a 12.288 MHz fundamental frequency is necessary for system timing. The 18 pF load capacitance must match the oscillator circuit's external capacitors. Consider the 50 Ohm ESR for drive level sensitivity. The 5x3.2mm package size suits space-constrained designs requiring standard SMD mounting.

Crystals Part Context

This part belongs to the CS53A series of surface-mount crystals from Transko Electronics. It shares dimensional similarities with other models in the family but differs in frequency and electrical parameters. The series offers various frequencies and package options for diverse timing applications.

Crystals Replacement Considerations

Direct substitutes include other 12.288 MHz crystals with identical 18 pF load capacitance and 50 Ohm ESR in a 5x3.2mm 4-SMD package. Verify pin compatibility and electrical tolerances before swapping manufacturers.
