TFA32C08DBER

Overview

The TFA32C08DBER is a fixed RF attenuator manufactured by Ohmite, designed for surface-mount applications in the 1206 (3216 Metric) package. It provides an attenuation value of 8 dB with a characteristic impedance of 50 Ohms. The device operates within a frequency range from 0 Hz to 20 GHz and supports a maximum power handling capacity of 125 mW. It features a thin-film construction suitable for wireless and RF integrated circuit environments, with an operating temperature range spanning from -40°C to +125°C.

Feature Summary

• Thin-film technology ensures stable performance across high-frequency ranges up to 20 GHz.
• Compact 1206 surface-mount package facilitates integration into space-constrained PCB designs.
• Robust thermal capability allows reliable operation at elevated temperatures up to 125°C.

Applications

• Wireless communication systems requiring precise signal level control
• RF test and measurement equipment calibration circuits
• Mobile device front-end modules for impedance matching and signal reduction

Procurement Notes

Verify component authenticity through authorized Ohmite distributors or certified suppliers. Confirm RoHS compliance status and lot traceability prior to procurement. Ensure storage conditions maintain integrity of the thin-film structure. Cross-reference datasheet revisions to confirm parameter consistency against current production batches.

Selection Notes

Select this component when a fixed 8 dB attenuation is required in a 50-Ohm system. The 1206 footprint suits standard SMT assembly lines. Consider the 125 mW power limit for thermal management in high-density layouts. Validate VSWR specifications against system sensitivity requirements for optimal signal integrity.

Part Context

This part belongs to Ohmite's TFA series of RF attenuators, which utilizes thin-film deposition techniques for precision resistance values. The series offers various attenuation levels and package sizes, including 0603, 0805, and 1206 configurations, catering to diverse RF design needs.

Replacement Considerations

Direct substitutes include other 8 dB, 50 Ohm, 1206 package RF attenuators from manufacturers such as Mini-Circuits or Qorvo, provided pinout and thermal characteristics match. Verify that alternative components meet the same 20 GHz frequency and 125 mW power ratings.
