TFA20C05DBER

Overview

The TFA20C05DBER is a surface-mount RF attenuator manufactured by Ohmite, designed for wireless and radio frequency integrated circuit applications. This component utilizes thin film technology to provide precise signal attenuation within the 0805 package footprint. It features a nominal attenuation value of 5 dB with a characteristic impedance of 50 Ohms. The device supports a maximum operating frequency of 20 GHz and maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.5. It operates reliably across a temperature range from -40°C to +125°C.

Feature Summary

• Thin film construction ensures stable performance in high-frequency environments
• Compact 0805 surface mount design facilitates automated PCB assembly
• Single-channel configuration provides dedicated signal path control

Applications

• RF signal conditioning in wireless communication systems
• Impedance matching networks in radio frequency circuits
• Signal level adjustment in test and measurement equipment

Procurement Notes

Verify the specific part number suffix against official Ohmite documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through current manufacturer declarations. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Check regional availability as distribution may vary by location.

Selection Notes

Select this component when a fixed 5 dB attenuation is required at 50 Ohms impedance. Consider the 0805 package size for space-constrained layouts. Verify that the 20 GHz frequency limit meets system requirements. Evaluate thermal management needs given the +125°C maximum operating temperature rating.

Part Context

This model belongs to the Ohmite TFA series of RF attenuators. The series includes variants with different attenuation values such as 3 dB, 9 dB, and 10 dB, all sharing similar electrical characteristics and packaging formats. These components are categorized under wireless and RF integrated circuits, serving as passive elements for signal management.

Replacement Considerations

Cross-reference with other Ohmite models like TFA20C03DBER or TFA20C09DBER if different attenuation levels are needed. Ensure any substitute matches the 0805 footprint, 50 Ohm impedance, and 20 GHz frequency capability. Verify pinout compatibility and thermal ratings before integration.
