TFA16C03DBER

Overview

The Ohmite TFA16C03DBER is a fixed thin film RF attenuator designed for surface mount applications in the 0603 package. It provides a nominal attenuation of 3 dB with a characteristic impedance of 50 Ohms and supports frequencies up to 20 GHz. The component features a maximum Voltage Standing Wave Ratio (VSWR) of 1.5 and operates within a temperature range of -40°C to +125°C. It is available in cut tape, reel, and MouseReel packaging formats.

Feature Summary

• Utilizes thin film technology for stable RF performance
• Compact 0603 surface mount footprint
• Wide frequency operation up to 20 GHz

Applications

• RF signal path conditioning
• Test and measurement equipment
• Wireless communication modules

Procurement Notes

Verify the specific suffix 'DBER' matches the required packaging format, as it indicates availability in Cut Tape, Reel, or MouseReel options. Confirm RoHS compliance status through official documentation prior to integration. Ensure the 0603 package dimensions align with the target PCB layout constraints and thermal management requirements for the intended operating environment.

Selection Notes

Select this model when a precise 3 dB attenuation value is required at 50 Ohms impedance. The 0603 size offers space efficiency compared to larger packages like 0805 or 1206. Consider the 20 GHz upper frequency limit and the -40°C to +125°C operating range to ensure suitability for high-frequency wireless applications and varying thermal conditions.

Part Context

This component belongs to the Ohmite TFA series of fixed thin film attenuators. The series includes variants in 0603, 0805, and 1206 packages with different attenuation values. The TFA16C03DBER specifically represents the 0603 form factor with 3 dB attenuation, sharing common electrical characteristics such as 50 Ohm impedance and 20 GHz bandwidth with other members of the family.

Replacement Considerations

Direct substitutes within the same series include TFA16C05DBER (5 dB), TFA16C09DBER (9 dB), and TFA16C10DBER (10 dB). For different attenuation needs in the same package, these parts are interchangeable physically. Other manufacturers may offer equivalent 0603 thin film attenuators, but pin compatibility and exact parameter matching must be verified.
