AT0603T04ECAC7

Attenuators Overview

The KYOCERA AVX AT0603T04ECAC7 is a surface-mount RF attenuator designed for high-frequency applications. It provides a nominal attenuation of 4 dB with a tolerance of ±0.75 dB across a frequency range from DC to 20 GHz. The component operates at a maximum power rating of 1 W and maintains a characteristic impedance of 50 Ohms. It features a maximum VSWR of 1.25 and utilizes ceramic technology within a compact 0603 (1608 metric) package. The device supports an operating temperature range from -55°C to +150°C, ensuring reliability in demanding environments.

Attenuators Feature Summary

• Provides precise 4 dB signal attenuation suitable for RF circuit calibration
• Operates effectively up to 20 GHz with low voltage standing wave ratio
• Handles 1 W power dissipation in a miniature SMD footprint

Attenuators Applications

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

Attenuators Procurement Notes

Verify the specific ordering suffix against official KYOCERA AVX documentation to ensure correct packaging and termination specifications. Confirm that the required attenuation value matches the design intent, as similar part numbers may offer different dB ratings. Check current availability status directly with the manufacturer or authorized distributors, as lead times may vary for this specialized component.

Attenuators Selection Notes

Select this component when a 4 dB fixed attenuation is required within a 50 Ohm system. Ensure the PCB layout accommodates the 0603 package dimensions and thermal requirements for 1 W dissipation. Verify that the operational frequency does not exceed 20 GHz and that the ambient temperature remains within the specified -55°C to +150°C range for optimal performance.

Attenuators Part Context

This part belongs to the KYOCERA AVX AT series of thin-film microwave attenuators. These components are engineered for high stability and precision in RF and microwave circuits. The series offers various attenuation values in standard SMD packages, providing designers with flexible options for signal management in compact electronic devices.

Attenuators Replacement Considerations

Consider the AT0603T03ECAC7 for 3 dB attenuation or the AT0603T05ECAC7 for 5 dB attenuation if the exact 4 dB value is not critical. Ensure any substitute maintains the same 50 Ohm impedance, 1 W power rating, and 0603 package size to fit existing board layouts without modification.
