ATC2525CT-1000JN-99TR

Attenuators Overview

The ATC2525CT-1000JN-99TR is a surface-mount RF attenuator manufactured by Vishay Barry Industries. It provides a fixed attenuation of 10 dB with a tolerance of ±5%. The device operates within a frequency range of DC to 2 GHz and features a nominal impedance of 50 Ohms. It supports a high power rating of 30 Watts, utilizing Beryllium Oxide (BeO) technology for thermal management. The component is housed in a 2525 package (6464 metric), designed for SMD/SMT installation.

Attenuators Feature Summary

• Utilizes Beryllium Oxide (BeO) substrate for enhanced thermal dissipation capabilities
• Designed for high-power applications with a 30 Watt power rating
• Fixed 10 dB attenuation value with precise ±5% tolerance
• Wraparound construction suitable for robust surface-mount integration

Attenuators Applications

• High-power RF signal conditioning circuits
• Microwave communication systems requiring stable attenuation
• Test and measurement equipment calibration stages
• Defense and aerospace radar subsystems

Attenuators Procurement Notes

Verify the specific suffix '99' corresponds to the BeO wraparound variant when sourcing. Confirm that the 2525 footprint matches the PCB layout requirements. Ensure handling procedures account for the ceramic nature of the BeO substrate. Cross-reference the manufacturer datasheet for reflow soldering profiles to prevent thermal shock during assembly processes.

Attenuators Selection Notes

Select this component when high power handling is critical alongside precise attenuation values. The 10 dB fixed value suits scenarios requiring significant signal reduction. Consider the 2525 package size for board space constraints. Verify thermal management needs align with the 30W rating and BeO conductivity properties for the intended operating environment.

Attenuators Part Context

This part belongs to the ATC series of chip attenuators from Vishay Barry Industries. The series offers various attenuation values and power ratings using different substrate technologies. The ATC2525CT designation indicates the specific package style and thermal characteristics associated with high-performance RF applications.

Attenuators Replacement Considerations

Direct substitutes include ATC2525CT-0600JN-99TR (6 dB) and ATC2525CT-0100JN-99TR (1 dB) if attenuation values differ. Other Vishay ATC series parts may serve as alternatives if power and frequency specs align.
