TFA20C10DBER

Overview

The TFA20C10DBER is a fixed thin film RF attenuator manufactured by Ohmite, designed for surface-mount applications in the 0805 (2012 Metric) package. It provides a nominal attenuation of 10 dB with a maximum operating frequency of 20 GHz and a characteristic impedance of 50 Ohms. The device supports a maximum power dissipation of 100 mW and maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.5. It operates within a temperature range of -40°C to +125°C and complies with RoHS standards.

Feature Summary

• Utilizes thin film technology for stable performance across a wide frequency range up to 20 GHz.
• Designed for high-reliability surface-mount integration in compact wireless and RF circuits.
• Maintains consistent impedance matching with low VSWR for signal integrity.

Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring precise attenuation
• Mobile device circuitry and base station components

Procurement Notes

Verify component authenticity through authorized Ohmite distributors or certified suppliers. Confirm RoHS compliance status and lot traceability upon receipt. Ensure storage conditions maintain thermal stability within specified limits. Cross-reference datasheet revisions to align with current manufacturing specifications before integration into production designs.

Selection Notes

Select this model when a 10 dB attenuation value is required at frequencies up to 20 GHz. The 0805 footprint suits space-constrained PCB layouts. Consider the 100 mW power rating for low-power signal paths. Compare against other TFA series variants if different attenuation values or package sizes like 0603 are needed.

Part Context

This component belongs to the Ohmite TFA series of fixed thin film attenuators. The series offers various attenuation values and package options including 0603, 0805, and 1206. The TFA20C10DBER specifically addresses the need for high-frequency precision in modern RF integrated circuits.

Replacement Considerations

Other models in the TFA20C series such as TFA20C03DBER or TFA20C08DBER offer different attenuation values but share similar electrical characteristics and packaging. Substitution requires verifying that the specific dB value meets circuit requirements without altering impedance or power handling capabilities.
