AT0904AS-1000JN-91TR

Attenuators Overview

The AT0904AS-1000JN-91TR is a surface-mount chip attenuator manufactured by Vishay Barry. It provides a nominal attenuation of 10 dB with a tolerance of ±5%. The device operates from DC to 18 GHz and handles a power rating of 100 mW (0.1 W). It utilizes an aluminum oxide substrate with platinum/gold wraparound construction in a 0904 package.

Attenuators Feature Summary

• Wraparound electrode construction for enhanced thermal dissipation
• Stable attenuation performance across the DC to 18 GHz frequency range
• Aluminum oxide substrate for high-frequency stability

Attenuators Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring precise attenuation
• Microwave circuit design for signal level control

Attenuators Procurement Notes

Verify the specific suffix '91TR' corresponds to the required tape-and-reel packaging configuration. Confirm that the 10 dB attenuation value and 5% tolerance meet the circuit requirements. Ensure the 100 mW power rating is sufficient for the intended application environment to prevent overheating or performance degradation during operation.

Attenuators Selection Notes

Select this component when a compact, high-frequency attenuator is needed for SMD assembly. The 0904 footprint suits space-constrained designs. Verify that the 18 GHz upper frequency limit aligns with the system bandwidth. Consider the platinum/gold metallization for reliability in demanding RF environments compared to standard terminations.

Attenuators Part Context

This part belongs to the ATC series of chip attenuators from Vishay Barry. These components are designed for use in microwave and millimeter-wave applications. The series offers various attenuation values and power ratings, utilizing robust ceramic substrates and thick-film technology for consistent performance in RF circuits.

Attenuators Replacement Considerations

Check datasheets for other AT0904AS variants with different attenuation values (e.g., 3 dB, 6 dB) if the 10 dB specification does not match. Verify pinout compatibility and thermal characteristics before substituting with parts from other manufacturers offering similar 0904 package attenuators.
