TFA20C01DBER

Overview

The TFA20C01DBER is a single-channel RF attenuator manufactured by Ohmite, designed for surface-mount applications in the 0805 (2012 Metric) package. It utilizes thin-film technology to provide a precise attenuation value of 1 dB across a frequency range from 0 Hz to 20 GHz. The component operates with a nominal impedance of 50 Ohms and maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.5. It is rated for an operating temperature range between -40°C and +125°C, ensuring reliability in demanding wireless and RF integrated circuit environments.

Feature Summary

• Thin-film construction for stable RF performance
• High-frequency operation up to 20 GHz
• Compact 0805 surface-mount footprint

Applications

• Wireless communication systems
• RF signal conditioning circuits
• Test and measurement equipment

Procurement Notes

Verify the specific part number suffix against official Ohmite documentation to confirm package type and tape/reel specifications. Ensure that procurement channels are authorized distributors to guarantee component authenticity and traceability. Cross-reference the manufacturer's datasheet for any recent updates regarding RoHS compliance status or environmental declarations before finalizing purchase orders.

Selection Notes

Select this component when a low-loss, high-precision attenuation value is required in compact RF designs. The 0805 package facilitates automated assembly processes. Engineers should verify that the 1 dB attenuation aligns with system gain requirements and that the 20 GHz bandwidth exceeds the operational frequency spectrum of the application.

Part Context

This model belongs to the TFA20C series of fixed-value RF attenuators from Ohmite. The series offers various attenuation steps within the same 0805 form factor, allowing designers to maintain consistent board layouts while adjusting signal levels. The TFA20C01DBER specifically addresses applications requiring minimal signal reduction with high linearity.

Replacement Considerations

Direct substitutes include other TFA20C series variants such as TFA20C03DBER or TFA20C09DBER if different attenuation values are acceptable. Alternative manufacturers may offer equivalent 0805 thin-film attenuators, but electrical parameters like VSWR and power handling must be verified against the original specification.
