TFA16C09DBER

Overview

The TFA16C09DBER is a fixed thin film RF attenuator manufactured by Ohmite, designed for surface mount applications in the 0603 (1608 metric) package. It provides a nominal attenuation of 9 dB with a maximum operating frequency of 20 GHz and a characteristic impedance of 50 Ohms. The component features a maximum VSWR of 1.5 and operates within a temperature range of -40°C to +125°C. It utilizes thin film technology and has a unit weight of 2 mg.

Feature Summary

• Utilizes thin film technology for stable performance in high-frequency environments
• Compact 0603 surface mount package design suitable for space-constrained PCB layouts
• Wide frequency operation capability up to 20 GHz
• Robust thermal stability across an extended industrial temperature range

Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring precise signal attenuation
• Microwave circuit designs operating at frequencies up to 20 GHz
• Mobile device RF front-end modules

Procurement Notes

Verify the specific suffix 'DBER' against the manufacturer's official datasheet to confirm the exact packaging configuration, as this indicates reel or cut tape availability. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Cross-reference the RoHS compliance status with current environmental regulations before finalizing orders.

Selection Notes

Select the TFA16C09DBER when a 9 dB attenuation value is required within a 50 Ohm system architecture. This component is appropriate for designs where a 0603 footprint is mandated due to board space limitations. Consider the 20 GHz frequency limit and 125°C maximum operating temperature to ensure compatibility with the application's thermal and spectral requirements.

Part Context

This part belongs to the Ohmite TFA series of fixed thin film attenuators. The series offers various attenuation values and package sizes, including 0603, 0805, and 1206. The TFA16C09DBER specifically represents the 0603 size variant with 9 dB attenuation, sharing common electrical characteristics such as 50 Ohm impedance and 20 GHz bandwidth with other members of the family.

Replacement Considerations

Direct substitutes within the same series include TFA16C05DBER (5 dB), TFA16C10DBER (10 dB), and TFA20C09DBER (0805 package). Verify pin compatibility and thermal ratings when considering alternative package sizes like the 0805 variant.
