TS500T33CDT

Crystals Overview

The TS500T33CDT is a surface-mount crystal oscillator manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 50.000 MHz with a frequency tolerance and stability of ±30 ppm. The component utilizes an HC-49/US-SM package and features a load capacitance of 18 pF. Its equivalent series resistance (ESR) is specified at 80 Ohms, and it supports third-overtone operation modes. The device is rated for an operating temperature range of -20°C to +70°C and is supplied in tape and reel packaging.

Crystals Feature Summary

• Third-overtone operation mode for high-frequency stability
• Surface-mount HC-49/US-SM package design
• ±30 ppm frequency tolerance and stability

Crystals Applications

• General-purpose clock signal generation
• Microcontroller system timing references
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific suffix 'CDT' against the official CTS datasheet to confirm the 18pF load capacitance and ±30ppm tolerance parameters. Ensure the ordering documentation matches the required frequency code and manufacturing site codes as mandated by the ATSSMTS series guidelines. Confirm RoHS compliance status prior to final procurement approval.

Crystals Selection Notes

Select this component when a 50 MHz surface-mount crystal with moderate stability requirements is needed. The HC-49/US-SM form factor allows for standard SMD assembly processes. Consider the 80 Ohm ESR value for circuit impedance matching. Verify that the ±30 ppm tolerance meets the system's timing accuracy constraints compared to tighter tolerance alternatives.

Crystals Part Context

This part belongs to the CTS ATSSMTS series of surface-mount crystals. The series provides various frequency options and package styles for embedded applications. The TS500T33CDT specifically addresses the need for compact, reliable frequency control solutions in space-constrained electronic designs requiring standardized mounting footprints.

Crystals Replacement Considerations

Cross-reference with TS500T33CET if higher stability or different packaging is acceptable. Verify pin compatibility and electrical parameters before substituting. Ensure the replacement part maintains the same operating temperature range and overtone mode to prevent circuit malfunction.
