ATS2012-04DB-FD-T1

Attenuators Overview

The Susumu ATS2012-04DB-FD-T1 is a high-frequency thin-film chip attenuator designed for surface-mount applications. It provides a nominal attenuation of 4 dB with a tolerance of ±2.5 dB across a frequency range from DC to 55 GHz. The component operates at a 50 Ohm impedance and features a maximum power rating of 100 mW. Physical dimensions correspond to the 0805 (2012 metric) package, ensuring compact integration into RF circuits.

Attenuators Feature Summary

• Thin-film construction ensures stable performance in high-frequency environments
• Wide operational bandwidth extending from DC to 55 GHz
• Compact 0805 surface-mount footprint for space-constrained designs

Attenuators Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring precise attenuation
• High-frequency circuit impedance matching networks

Attenuators Procurement Notes

Verify the specific suffix FD against official datasheets to confirm tolerance and packaging specifications. Ensure compatibility with standard SMT reflow processes. Confirm that the 55 GHz maximum frequency aligns with system requirements. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Attenuators Selection Notes

Select this component when a 4 dB attenuation value is required within a 50 Ohm system. The 100 mW power rating suits low-to-medium power RF paths. Consider the 0805 package size for board space limitations. Validate that the ±2.5 dB tolerance meets the system's error budget for the intended frequency band up to 55 GHz.

Attenuators Part Context

This part belongs to the ATS2012 series of high-frequency chip attenuators by Susumu. The series utilizes thin-film technology to achieve consistent electrical characteristics over a broad frequency spectrum. The 0805 form factor allows for automated placement in modern PCB manufacturing workflows.

Attenuators Replacement Considerations

Direct substitutes include other ATS2012 series variants with different attenuation values, such as ATS2012-02DB-FD-T1 or ATS2012-03DB-FD-T1, provided the attenuation difference is acceptable. Cross-brand replacements require matching the 55 GHz frequency limit, 50 Ohm impedance, and 0805 package dimensions.
