AT0603T01ECATD

Attenuators Overview

The AT0603T01ECATD is a thin-film RF attenuator manufactured by KYOCERA AVX, designed for surface-mount applications in the 0603 (1608 metric) package. It provides a nominal attenuation of 1 dB with a tolerance of ±0.50 dB from DC to 10 GHz and ±1 dB from 10 GHz to 20 GHz. The component operates at a maximum power rating of 1 W and features a 50 Ohm impedance. It exhibits a maximum VSWR of 1.25 and functions within a temperature range of -55°C to +150°C.

Attenuators Feature Summary

• Utilizes thin-film technology for stable RF performance across a wide frequency spectrum.
• Engineered for high-temperature operation suitable for demanding industrial environments.
• Compact SMD form factor facilitates automated assembly and space-constrained designs.

Attenuators Applications

• RF signal conditioning in wireless communication infrastructure
• Test and measurement equipment requiring precise signal attenuation
• Automotive radar systems operating at high temperatures

Attenuators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tolerance specifications. Confirm that the required attenuation value and power handling capabilities align with the system design requirements before procurement. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Attenuators Selection Notes

Select this component when a fixed 1 dB attenuation is required in a compact footprint. Ensure the application frequency does not exceed 20 GHz and that the input power remains within the 1 W limit. Consider the thermal management capabilities of the PCB, as the device supports operation up to +150°C, making it suitable for high-heat environments where standard components might fail.

Attenuators Part Context

This part belongs to the AT series of thin-film attenuators from KYOCERA AVX, which offers various attenuation values in the 0603 package. The series is characterized by its broad bandwidth and high reliability, targeting applications in aerospace, defense, and industrial sectors where consistent performance over temperature variations is critical.

Attenuators Replacement Considerations

Direct substitutes include other parts from the same AT series with different attenuation values, such as AT0603T00ECATD or AT0603T04ECATD, provided the circuit design allows for adjusted signal levels. Cross-brand replacements require careful verification of pin compatibility, thermal characteristics, and RF performance curves.
