AT0603T03ECATB

Attenuators Overview

The AT0603T03ECATB is a surface-mount RF attenuator manufactured by KYOCERA AVX. It provides a fixed attenuation of 3 dB with a maximum operating frequency of 20 GHz and a nominal impedance of 50 Ohms. The device supports a power rating of 1 W and operates within a temperature range of -55°C to +150°C. Housed in a compact 0603 (1608 metric) package, it utilizes SMD/SMT mounting technology for integration into high-frequency circuits.

Attenuators Feature Summary

• Fixed 3 dB attenuation value for precise signal level control
• Broadband operation extending from DC to 20 GHz
• High thermal stability supporting operation up to +150°C
• Compact 0603 surface-mount footprint for space-constrained designs

Attenuators Applications

• RF signal conditioning in wireless communication systems
• Impedance matching networks in microwave circuits
• Signal level adjustment in test and measurement equipment
• Attenuation stages in broadband amplifier chains

Attenuators Procurement Notes

Verify the specific manufacturer ordering requirements and current availability status directly with authorized distributors or the manufacturer before placing orders. Confirm that the component meets all necessary environmental compliance standards, such as RoHS3, for the intended application region. Ensure that the supply chain sources are verified to prevent counterfeit components.

Attenuators Selection Notes

Select this component when a fixed 3 dB attenuation is required at frequencies up to 20 GHz. The 1 W power rating and wide temperature range make it suitable for demanding environments. Consider the 0603 package size for board space limitations. Ensure the system impedance matches the 50 Ohm specification to maintain signal integrity and minimize reflections.

Attenuators Part Context

This part belongs to the AT series of thin-film attenuators from KYOCERA AVX. These components are designed for high-reliability applications requiring stable performance across broad frequency bands. The series offers various attenuation values in standard SMD packages, providing engineers with flexible options for RF circuit design without compromising on size or thermal performance.

Attenuators Replacement Considerations

Compatible substitutes include other 0603 package attenuators with 3 dB attenuation and 20 GHz bandwidth, such as the AT0603T02ECATB for different attenuation needs. Verify that alternative parts match the 50 Ohm impedance, 1 W power rating, and operating temperature range to ensure functional equivalence in existing designs.
