AT0603C08ECAS3

Attenuators Overview

The AT0603C08ECAS3 is a surface-mount RF attenuator from the KYOCERA AVX AT series, housed in a compact 0603 (1608 metric) package. It provides a nominal attenuation of 8 dB with a tolerance of ±0.75 dB across a frequency range of DC to 20 GHz. The component operates at a 50 Ohm impedance and supports a power rating of 1 Watt. Key electrical specifications include a maximum VSWR of 1.25 and an operating temperature range from -55°C to +150°C. Manufactured using thin-film ceramic technology, it is designed for high-reliability applications requiring precise signal control in microwave circuits.

Attenuators Feature Summary

• Provides stable 8 dB attenuation with tight tolerance for precision signal management
• Operates effectively up to 20 GHz for wideband RF and microwave applications
• Features low VSWR to minimize signal reflection and maintain transmission integrity
• Supports high power handling within a compact SMD footprint

Attenuators Applications

• RF test and measurement equipment requiring precise signal level adjustment
• Wireless communication systems including base stations and mobile devices
• Microwave circuit design for signal conditioning and impedance matching
• Automotive radar and infotainment systems operating at high frequencies

Attenuators Procurement Notes

Verify the specific suffix 'S3' against official KYOCERA AVX documentation to confirm packaging type and tape/reel specifications. Ensure compatibility with standard SMT reflow profiles and check RoHS compliance status for environmental regulations. Confirm that the 1W power rating aligns with thermal management requirements in the final assembly.

Attenuators Selection Notes

Select this component when a fixed 8 dB attenuation is required in a space-constrained 0603 footprint. It is suitable for designs needing operation up to 20 GHz with minimal signal reflection. Consider the 1W power rating for high-power RF paths and verify that the ±0.75 dB tolerance meets the system's accuracy requirements. Compare with other AT series variants if different attenuation values or packages are needed.
