ATC2525CT-0300JN-99TR

Attenuators Overview

The ATC2525CT-0300JN-99TR is a surface-mount RF attenuator manufactured by Vishay / Barry Industries. It provides a fixed attenuation of 3 dB with a tolerance of ±5%. The device operates from DC to 2 GHz and maintains a nominal impedance of 50 Ohms. It features a high power rating of 30 W and utilizes Beryllium Oxide (BeO) technology for thermal management. The component is housed in a 2525 (6464 metric) package, suitable for SMD/SMT installation. It supports an operating temperature range from -55°C to +150°C.

Attenuators Feature Summary

• Utilizes Beryllium Oxide (BeO) substrate for enhanced thermal dissipation capabilities.
• Designed for high-power applications with a 30 W power handling rating.
• Features a wraparound electrode structure for robust electrical connections.

Attenuators Applications

• High-power RF signal conditioning
• Test and measurement equipment
• Wireless communication systems

Attenuators Procurement Notes

Verify the specific suffix codes against official Vishay documentation to ensure correct material composition and tolerance specifications. Confirm that the BeO substrate aligns with your thermal requirements. Check RoHS compliance status as indicated in the datasheet. Ensure the 2525 footprint matches your PCB layout constraints before ordering.

Attenuators Selection Notes

Select this component when a 3 dB attenuation value is required at frequencies up to 2 GHz. The 30 W power rating makes it suitable for high-power environments where standard ceramic attenuators may fail. Consider the BeO material properties for superior heat transfer compared to alumina alternatives in dense circuit layouts.

Attenuators Part Context

This part belongs to the ATC series of chip attenuators from Vishay / Barry Industries. These components are designed for reliability in demanding RF applications. The ATC2525CT variant specifically addresses high-power needs using advanced substrate materials. It complements other values in the series such as 1 dB and 10 dB options.

Attenuators Replacement Considerations

Cross-reference with ATC2525CT-0100JN-99TR for 1 dB attenuation or ATC2525CT-3000JN-99TR for 30 dB attenuation within the same series. Verify that substitute parts maintain the same 50 Ohm impedance and 2 GHz frequency limit. Ensure the replacement offers equivalent 30 W power handling if thermal performance is critical.
