AT0405GA-0100JN-91TR

Attenuators Overview

The Vishay Barry AT0405GA-0100JN-91TR is a surface-mount chip attenuator designed for RF and wireless applications. It provides a fixed attenuation of 1 dB with a tolerance of 5%. The device operates from DC to 4 GHz and handles a power rating of 0.15 W. Constructed with an aluminum oxide (Al2O3) substrate, it features a gold wraparound termination style in a 0405 package.

Attenuators Feature Summary

• Utilizes a 3-sided wraparound gold termination structure for enhanced thermal dissipation and reliable electrical contact.
• Built on a stable aluminum oxide ceramic substrate to maintain consistent performance across the operating frequency range.
• Designed for surface mount technology integration, facilitating automated assembly processes.

Attenuators Applications

• RF signal conditioning in wireless communication systems
• Attenuation stages in test and measurement equipment
• Signal level adjustment in microwave circuit boards

Attenuators Procurement Notes

Verify the manufacturer part number AT0405GA-0100JN-91TR against official Vishay Barry documentation to confirm specifications. Ensure the component matches the required 1 dB attenuation value and 0.15 W power rating for your specific design. Check RoHS compliance status if environmental regulations apply to your project requirements.

Attenuators Selection Notes

Select this component when a low-value fixed attenuation is required for high-frequency stability up to 4 GHz. The 0405 footprint suits compact PCB layouts. Consider the 0.15 W power limit for thermal management. Verify that the aluminum oxide substrate aligns with your dielectric requirements compared to alternative materials like beryllium oxide.

Attenuators Part Context

This part belongs to the Vishay Barry ATC series of wirewound chip attenuators. These components are engineered for precision RF applications requiring stable attenuation values. The series offers various resistance and attenuation options, utilizing different substrate materials to balance cost, power handling, and frequency performance for diverse electronic designs.

Attenuators Replacement Considerations

Direct substitutes include other Vishay Barry models within the ATC series offering similar 1 dB attenuation and 0405 packaging. Cross-reference with equivalent parts from other manufacturers only if they match the 4 GHz frequency limit, 0.15 W power rating, and SMD form factor precisely.
