Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact attenuation values and tolerance levels. Ensure that the selected variant matches the required impedance and frequency specifications for the target application. Cross-reference datasheet parameters regarding thermal limits and VSWR ratings prior to integration into final designs.

Selection Notes

Select this component based on the required attenuation value and frequency range compatibility. Consider the physical size constraints imposed by the 0805 package when designing PCB layouts. Evaluate the thermal operating range requirements against the specified -40°C to +125°C limits. Confirm impedance matching needs align with the standard 50 Ohm specification provided in the technical data.

Part Context

This component belongs to the TFA20 series of RF attenuators produced by Ohmite. The series offers various attenuation values within the same 0805 form factor, allowing for consistent design practices across different signal processing requirements. These devices are categorized under wireless and RF integrated circuits, serving as passive components for signal management in high-frequency electronic systems.

Replacement Considerations

Compatible substitutes within the TFA20 series include TFA20C03DBER, TFA20C04DBER, TFA20C08DBER, TFA20C09DBER, and TFA20C10DBER. These alternatives share identical packaging and general electrical characteristics but differ in their specific attenuation values. Verify that the substitute part meets the exact dB requirement of the circuit design.
