TFA20C00DBER

Overview

The TFA20C00DBER is a fixed thin film RF attenuator manufactured by Ohmite, designed for surface mount applications in the 0805 package. It provides a nominal attenuation of 0 dB with a 50 Ohm impedance and operates up to a maximum frequency of 20 GHz. The component supports a voltage standing wave ratio (VSWR) of 1.5 maximum and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Utilizes thin film technology for stable RF performance
• Designed for high-frequency operation up to 20 GHz
• Available in compact 0805 surface mount package

Applications

• RF signal path conditioning
• Impedance matching networks
• Wireless communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific part number suffix against official Ohmite documentation to confirm package type and tolerance specifications. Ensure that the selected variant meets the required thermal and electrical ratings for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when a zero-decibel insertion loss is required while maintaining controlled impedance and high-frequency stability. Consider the 0805 footprint constraints and the operating temperature range limits when integrating into the circuit design.

Part Context

This part belongs to the Ohmite TFA series of fixed thin film attenuators. The series offers various attenuation values in standard SMD packages including 0603, 0805, and 1206, providing consistent performance across wide frequency ranges for RF integrated circuits.

Replacement Considerations

Consult Ohmite datasheets for direct substitutes within the TFA series offering identical 0 dB attenuation and 0805 packaging. Verify compatibility with existing PCB layouts and thermal management requirements when considering alternative manufacturers.
