TFA32C00DBER

Overview

The TFA32C00DBER is a surface-mount RF attenuator manufactured by Ohmite, designed for high-frequency applications up to 20 GHz. It features a 1206 (3216 Metric) package and utilizes thin-film technology for precise resistance values. The component operates with a nominal attenuation of 0 dB, maintaining a standard 50 Ohm impedance across its single channel. It exhibits a maximum Voltage Standing Wave Ratio (VSWR) of 1.5, ensuring signal integrity in RF circuits. The device supports an operating temperature range from -40°C to +125°C and is available in Reel, Cut Tape, and MouseReel packaging formats.

Feature Summary

• Thin-film construction ensures stable performance in high-frequency RF environments
• Surface-mount design facilitates automated assembly in compact electronic devices
• Wide operational temperature range supports reliability in harsh conditions

Applications

• RF signal conditioning in wireless communication systems
• Impedance matching networks in microwave circuits
• Test and measurement equipment requiring precise signal control

Procurement Notes

Verify the specific suffix 'DBER' corresponds to the required packaging format (Cut Tape or Reel) as listed in the official Ohmite datasheet. Confirm RoHS compliance status through the manufacturer's documentation before integration. Ensure the 1206 footprint matches the PCB layout constraints. Cross-reference the part number with authorized distributors to confirm current availability and lead times.

Selection Notes

Select this component when a 0 dB attenuation value is required within a 1206 SMD form factor. The 20 GHz frequency rating makes it suitable for advanced RF applications. Consider the thin-film technology for better stability compared to thick-film alternatives. Verify that the 50 Ohm impedance aligns with the system design requirements. Check thermal management needs given the +125°C maximum operating temperature.
