Detailed Description for TC1.33-282+
Product Overview
TC1.33-282+ is a mini wideband tri-filar transformer measured in a 75 Ω system, with a 1:1.33 impedance ratio and a 5 MHz to 2.8 GHz frequency range. It is designed for broadband paths that need both single-ended-to-balanced conversion and a controlled impedance step between coaxial infrastructure and differential electronics.
The plastic-substrate device measures roughly 4 mm on each side and uses a five-pad AT224-1A construction. Its very wide passband makes it relevant to multi-service CATV, DOCSIS, tuner and broadband access equipment. The non-unity ratio and 75 Ω characterization should remain explicit in a replacement comparison; matching only the package and frequency span is insufficient.

Quality & Sourcing
Antrex Electronics can assist with sourcing TC1.33-282+ for CATV, broadband and 75 Ω RF assemblies. A replacement should be checked for the same 75 Ω characterization, winding ratio, center-tap arrangement where present, package geometry and usable frequency range rather than selected only by transformer family name.
