TFA20C07DBER

Overview

The TFA20C07DBER 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 7 dB with a characteristic impedance of 50 Ohms and operates across a frequency range up to 20 GHz. The component supports a maximum Voltage Standing Wave Ratio (VSWR) of 1.5 and functions within an operating temperature range from -40°C to +125°C.

Feature Summary

• Utilizes thin film technology for stable RF signal attenuation
• Designed for high-frequency operation up to 20 GHz
• Optimized for compact 0805 surface mount integration

Applications

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

Procurement Notes

Verify availability through authorized Ohmite distributors or electronic component retailers. Confirm RoHS compliance status via official datasheets before procurement. Ensure storage conditions align with manufacturer specifications to maintain component integrity during handling and assembly processes.

Selection Notes

Select this model when a 7 dB fixed attenuation value is required in an 0805 footprint. Consider the 20 GHz frequency limit and 50 Ohm impedance matching requirements. Evaluate thermal performance capabilities within the specified -40°C to +125°C operational range for the target application environment.

Part Context

This part belongs to the Ohmite TFA series of fixed thin film attenuators. The series offers various attenuation values in 0603, 0805, and 1206 packages. The TFA20C07DBER specifically addresses needs for moderate attenuation in high-frequency 0805 designs.

Replacement Considerations

Compatible substitutes include other TFA series variants such as TFA20C08DBER or TFA20C09DBER for different attenuation levels. Cross-reference technical parameters like VSWR and frequency response to ensure functional equivalence.
