TFA32C03DBER

Overview

The TFA32C03DBER is a single-channel RF attenuator manufactured by Ohmite, designed for wireless and radio frequency integrated circuit applications. It utilizes thin film technology to provide a fixed attenuation of 3 dB with a nominal impedance of 50 Ohms. The component supports a maximum operating frequency of 20 GHz and maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.5. It operates within a temperature range of -40°C to +125°C. The device is available in a 1206 surface-mount package and complies with RoHS standards.

Feature Summary

• Thin film construction ensures stable RF performance across high-frequency bands up to 20 GHz.
• Wide operational temperature range supports reliability in demanding environments from -40°C to +125°C.
• Low VSWR characteristic maintains signal integrity in 50 Ohm transmission lines.

Applications

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

Procurement Notes

Verify the specific manufacturer part number against official Ohmite documentation to confirm technical specifications. Ensure compatibility with standard 1206 footprint requirements during integration. Confirm that the selected variant meets all necessary regulatory compliance standards for the intended deployment environment.

Selection Notes

Select this component when a precise 3 dB attenuation is required at frequencies approaching 20 GHz. The 1206 package offers a balance between power handling and board space efficiency compared to smaller footprints. Consider the wide temperature rating for applications subject to thermal variation.

Part Context

This model belongs to Ohmite's TFA series of surface-mount RF attenuators. These components are engineered for consistent performance in compact electronic designs. The series provides various attenuation values while maintaining uniform impedance and frequency characteristics across different package sizes.

Replacement Considerations

TFA20C03DBER: Offers identical electrical specifications but utilizes an 0805 package instead of 1206. Verify mechanical footprint compatibility before substitution.
