ATC2525CT-0100JN-99TR

Attenuators Overview

The ATC2525CT-0100JN-99TR is a surface-mount RF attenuator manufactured by Vishay Barry. It provides a nominal attenuation of 1dB with a tolerance of ±5%. The device operates within a frequency range of DC to 2 GHz and maintains a characteristic impedance of 50 Ohms. It is designed for high-power applications, supporting an input power rating of 30 Watts. The component utilizes Beryllium Oxide (BeO) material for the resistive element and features a wraparound construction. It is housed in a 2525 package (6464 metric) and is compliant with RoHS standards.

Attenuators Feature Summary

• Utilizes Beryllium Oxide (BeO) material for the resistive element to ensure thermal stability and high power handling capabilities.
• Features a 3-sided wraparound chip design that enables stable attenuation performance across the specified frequency band.
• Supports solder mounting for reliable integration into surface-mount assembly processes.

Attenuators Applications

• RF signal conditioning in microwave communication systems
• Attenuation stages in test and measurement equipment
• Power management in radar and electronic warfare systems

Attenuators Procurement Notes

Verify the specific suffix '99' indicates the BeO material variant, distinct from the '94' Al2O3 version. Confirm the 30W power rating aligns with your thermal design requirements. Ensure the 2525 footprint matches your PCB layout. Check for RoHS compliance status if required by your manufacturing standards. Validate the ±5% tolerance against your circuit's precision needs.

Attenuators Selection Notes

Select this component when a low attenuation value near 1dB is required alongside high power handling up to 30W. The BeO material offers superior thermal conductivity compared to alumina alternatives. The 2525 package size should be evaluated against available board space. Consider the 2 GHz upper frequency limit to ensure it meets the operational bandwidth of the target application without significant parasitic effects.

Attenuators Part Context

This part belongs to the ATC2525CT series of 3-sided wraparound chip attenuators. These components are characterized by their ability to provide stable attenuation from DC to 5 GHz, although this specific model is rated for 2 GHz. The series includes various attenuation values ranging from 0 to 30 dB and power ratings from 5W to 30W, utilizing either BeO or Al2O3 substrates depending on the suffix.

Attenuators Replacement Considerations

The ATC2525CT-0100JN-94TR is a similar model but uses Al2O3 material and has a lower 15W power rating. Direct substitution requires verifying thermal management capabilities. Other Vishay models in the ATC2525CT family may offer different attenuation values or power ratings but must be checked for pin compatibility and electrical specifications.
