ATC2525CT-2000JN-99TR

Attenuators Overview

The ATC2525CT-2000JN-99TR is a surface-mount RF attenuator manufactured by Vishay Barry. It provides a fixed attenuation of 20 dB with a tolerance of ±5%. The component operates within a frequency range from DC to 2 GHz and features a nominal impedance of 50 Ohms. It is designed for high-power applications, supporting a power rating of 30 W. The device utilizes Beryllium Oxide (BeO) ceramic technology and employs a wraparound construction method. It is housed in a 2525 (6464 metric) package, suitable for SMD/SMT mounting.

Attenuators Feature Summary

• Utilizes Beryllium Oxide (BeO) substrate for enhanced thermal conductivity and heat dissipation capabilities.
• Employs a wraparound resistive element construction to ensure structural integrity under high-power conditions.
• Provides precise fixed attenuation values with tight tolerance specifications for signal control accuracy.
• Designed for direct surface-mount integration into high-frequency circuit boards.

Attenuators Applications

• High-power RF signal conditioning in communication systems
• Attenuation stages in radar and electronic warfare equipment
• Test and measurement instrumentation requiring stable high-power handling
• Military and aerospace RF front-end modules

Attenuators Procurement Notes

Verify the specific suffix '99' corresponds to the BeO material and wraparound construction variant, as suffixes define critical physical properties. Confirm RoHS compliance status, as BeO components may have specific regulatory classifications distinct from standard lead-free parts. Ensure procurement channels provide original manufacturer documentation to validate the 30W power rating and 2 GHz frequency limit against counterfeit risks.

Attenuators Selection Notes

Select this component when high power dissipation is required alongside precise attenuation at frequencies up to 2 GHz. The BeO substrate offers superior thermal performance compared to alumina alternatives. Consider the 2525 package dimensions for PCB layout constraints. Evaluate the 5% tolerance requirement against system budget needs. This part is suitable for environments where thermal management is critical due to the 30W power handling capability.

Attenuators Part Context

This model belongs to the ATC2525 series of high-power chip attenuators from Vishay Barry. The series is characterized by its use of robust ceramic substrates and wraparound designs. The '2000' designation indicates the 20 dB attenuation value, while '99' specifies the BeO material and packaging style. It serves as a rugged solution for demanding RF applications where standard thin-film attenuators would fail due to thermal limitations.

Attenuators Replacement Considerations

Publicly confirmed substitutes include the ATC2525CT-2000JN-94TR, which shares the same electrical specifications but uses Alumina (Al2O3) instead of BeO. Verify that the thermal requirements of the application can be met by the alternative substrate material before swapping.
