TFA16C05DBER

Overview

The TFA16C05DBER is a fixed thin film RF attenuator manufactured by Ohmite, designed for surface-mount applications in the standard 0603 (1608 Metric) package. This single-channel component provides a precise attenuation value of 5 dB with a nominal impedance of 50 Ohms. It operates effectively within a frequency range extending from DC to a maximum of 20 GHz. The device maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.5, ensuring signal integrity across its operational bandwidth. It supports an extended temperature range from -40°C to +125°C, making it suitable for demanding electronic environments.

Feature Summary

• Utilizes thin film technology for stable and precise resistance characteristics in high-frequency circuits.
• Engineered for compact integration into space-constrained designs using the standard 0603 footprint.
• Capable of consistent performance up to 20 GHz with controlled VSWR for minimal signal reflection.

Applications

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

Procurement Notes

Verify that the specific part number matches the required 5 dB attenuation and 0603 package dimensions before integration. Confirm compliance with RoHS directives if environmental regulations apply to the final assembly. Ensure handling procedures account for the sensitivity of thin film components during surface mount placement. Check datasheet specifications for power rating limits to prevent thermal degradation during operation.

Selection Notes

Select this component when a 5 dB reduction is required in a 50 Ohm system operating up to 20 GHz. The 0603 size is ideal for high-density PCB layouts where space is limited compared to larger packages like 0805 or 1206. Consider the -40°C to +125°C operating range for applications exposed to extreme thermal conditions. Thin film construction offers superior stability over time compared to other resistor technologies in RF paths.

Part Context

This component belongs to the Ohmite TFA series of fixed thin film attenuators. The series includes various attenuation values and package sizes, such as 0805 and 1206, to accommodate different design constraints. The TFA16C05DBER specifically addresses the need for low-profile, high-frequency attenuation in modern electronics. It complements other passive components in RF front-end modules and distribution networks.

Replacement Considerations

Direct substitutes within the same series include TFA16C09DBER and TFA16C10DBER, which share the 0603 package but offer different attenuation values of 9 dB and 10 dB respectively. For identical 5 dB attenuation in alternative footprints, consider the TFA20C05DBER (0805) or TFA32C05DBER (1206). Verify that any replacement maintains the 50 Ohm impedance and 20 GHz frequency capability.
