TFA32C04DBER

Overview

The TFA32C04DBER is a surface-mount RF attenuator manufactured by Ohmite, designed for wireless and radio frequency integrated circuit applications. It utilizes thin film technology to provide precise signal attenuation within a compact 1206 package. The component operates with a nominal impedance of 50 Ohms and supports frequencies up to 20 GHz. It offers a fixed attenuation value of 4 dB with a maximum Voltage Standing Wave Ratio (VSWR) of 1.5. The device functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

• Thin film construction ensures stable performance in high-frequency environments
• Compact 1206 footprint suitable for space-constrained PCB layouts
• Wide operational temperature range for diverse environmental conditions

Applications

• Wireless communication systems
• Radio frequency integrated circuits
• Signal conditioning in RF test equipment

Procurement Notes

Verify the specific part number suffix against official Ohmite documentation to confirm exact electrical tolerances and packaging options. Confirm RoHS compliance status through current manufacturer declarations. Check regional distribution availability as supply may vary by location. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to assembly.

Selection Notes

Select this component when a 4 dB attenuation value is required at 50 Ohms impedance. The 1206 package size dictates board space requirements. Verify that the 20 GHz frequency limit meets system bandwidth needs. Consider the thin film technology for stability compared to other resistor technologies in RF paths.

Part Context

This part belongs to the Ohmite TFA series of RF attenuators. Similar models include TFA32C00DBER and TFA32C09DBER, which share the same 1206 package and thin film technology but offer different attenuation values such as 0 dB or 9 dB. All variants maintain consistent impedance and frequency specifications.

Replacement Considerations

Direct substitutes include TFA32C00DBER and TFA32C09DBER if attenuation values differ. Cross-reference pinout and thermal characteristics before substitution.
