TFA20C03DBER

Overview

The TFA20C03DBER is a fixed RF attenuator manufactured by Ohmite, designed for surface-mount applications in the 0805 (2012 Metric) package. This component provides a nominal attenuation of 3 dB with a maximum operating frequency of 20 GHz and a characteristic impedance of 50 Ohms. It features a single channel configuration and maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.5. The device utilizes thin film technology and operates within a temperature range of -40°C to +125°C. It is RoHS compliant and available in cut tape, reel, and MouseReel packaging formats.

Feature Summary

• Thin film construction ensures stable performance across high-frequency operations up to 20 GHz.
• Compact 0805 surface mount footprint facilitates integration into space-constrained wireless and RF circuits.
• Wide operational temperature range supports reliability in demanding environmental conditions.

Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring precise signal attenuation
• Microwave circuit design for impedance matching and power control

Procurement Notes

Verify the specific suffix and manufacturer part number against official Ohmite documentation to ensure compatibility with design requirements. Confirm that the selected packaging format meets production line specifications. Check regional availability as distribution status may vary. Ensure compliance with relevant regulatory standards such as RoHS before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 3 dB attenuation is required at frequencies up to 20 GHz. Consider the 0805 package size for board space constraints. Evaluate the thermal management capabilities given the wide operating temperature range. Compare VSWR specifications against system requirements to ensure signal integrity is maintained throughout the application.

Part Context

This part belongs to Ohmite's TFA series of RF attenuators, which are designed for high-frequency applications. The series offers various attenuation values while maintaining consistent electrical characteristics and package dimensions. These components are categorized under wireless and RF integrated circuits, serving as passive elements for signal management in modern electronic designs.

Replacement Considerations

Consult official Ohmite documentation for direct substitutes within the TFA series. Verify that alternative parts match the 3 dB attenuation, 20 GHz frequency limit, and 0805 package dimensions. Cross-reference impedance and VSWR specifications to ensure functional equivalence in the target circuit.
