TFA32C06DBER

Overview

The TFA32C06DBER is a fixed thin-film RF attenuator manufactured by Ohmite, designed for surface-mount applications in the 1206 (3216 Metric) package. It provides a precise attenuation value of 6 dB across a frequency range from 0 Hz to 20 GHz. The component operates with a characteristic impedance of 50 Ohms and supports a maximum power handling capacity of 125 mW. Key electrical specifications include a maximum Voltage Standing Wave Ratio (VSWR) of 1.5 and a single-channel configuration. The device is rated for operation within a temperature range of -40°C to +125°C, ensuring reliability in demanding wireless and RF environments.

Feature Summary

• Utilizes thin-film technology for stable RF performance
• Fixed attenuation design eliminates variable adjustment requirements
• Wideband frequency response supporting up to 20 GHz
• Compact 1206 surface-mount footprint for space-constrained PCBs

Applications

• RF transceiver signal conditioning
• Test and measurement equipment calibration
• Wireless communication system impedance matching
• High-frequency circuit protection and level setting

Procurement Notes

Verify that the specific part number matches the required 6 dB attenuation value, as the TFA series includes variants with different attenuation levels such as 0 dB or other values. Confirm the 1206 package dimensions align with the target PCB layout. Ensure the supplier provides official datasheets confirming the 20 GHz frequency limit and 125 mW power rating. Check RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a fixed 6 dB reduction is required in high-frequency circuits operating up to 20 GHz. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the 1206 package size for board space limitations. Verify thermal management capabilities given the 125 mW power dissipation limit and the specified operating temperature range of -40°C to +125°C for robustness in varied environments.

Part Context

This component belongs to the Ohmite TFA series of thin-film RF attenuators, which are engineered for precision in wireless and RF integrated circuits. The series offers various attenuation values and package options, including 0805 and 1206 sizes. These devices are characterized by their stability and wide bandwidth, making them suitable for modern high-speed communication systems requiring reliable signal attenuation without introducing significant distortion.

Replacement Considerations

Direct substitutes may include other Ohmite TFA series parts with identical 1206 packaging and 6 dB attenuation, such as TFA32C06D. Cross-manufacturer replacements require verification of matching 50 Ohm impedance, 20 GHz frequency range, and 125 mW power rating. Ensure any alternative maintains the same thin-film construction and VSWR specifications to preserve circuit performance integrity.
