CS63A-F2030FM20-28.63636M-TR

Crystals Overview

The CS63A-F2030FM20-28.63636M-TR is a ceramic surface-mount crystal manufactured by Transko Electronics, Inc. It operates at a fundamental frequency of 28.63636 MHz with a frequency tolerance of ±20 ppm. The component features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 40 Ohms. It is housed in a 4-SMD, no-lead package designed for automated assembly processes.

Crystals Feature Summary

• Utilizes ceramic material construction for stable frequency generation
• Designed for surface-mount technology integration
• Provides precise frequency control within specified tolerance limits

Crystals Applications

• Telecommunications equipment signal processing
• Frequency synthesizer circuits
• General electronic timing references

Crystals Procurement Notes

Verify the specific ordering suffix FM20 against official Transko documentation to confirm the exact load capacitance and ESR specifications. Ensure the tape and reel packaging designation matches production line requirements. Cross-reference the frequency value to prevent confusion with similar part numbers sharing the same base model prefix but differing in electrical parameters.

Crystals Selection Notes

Select this component when a 28.63636 MHz output is required with a 20 pF load capacitance. Consider the 40 Ohm ESR limit for oscillator circuit compatibility. Evaluate the 4-SMD no-lead form factor against available PCB footprint constraints. Confirm that the ±20 ppm stability meets the system's timing accuracy requirements compared to higher precision alternatives.

Crystals Part Context

This part belongs to the CS63A series of ceramic SMD crystals from Transko Electronics. The series typically includes variants with different frequencies, load capacitances, and package sizes. The CS63A designation indicates a specific ceramic construction profile distinct from other Transko product lines like the CS21 or TCRO series.

Crystals Replacement Considerations

Direct substitutes include CS21-F2020CQ10-28.63636M-TR if the lower ESR and capacitance are acceptable. Verify pinout and mechanical dimensions before swapping. No other direct equivalents are confirmed in public data.
