Mini-Circuits 1:1.33 CORE & WIRE Transformer, 5 - 2800 MHz, 75Ω TC1.33-282+

The TC1.33-282+ is a mini wideband tri-filar RF transformer designed for balanced-to-unbalanced impedance conversion between 100Ω and 75Ω across a frequency range of 5 to 2800 MHz. It has a 5-pad surface mount package with physical dimensions of 3.81 mm × 3.81 mm × 4.06 mm and is aqueous washable and RoHS compliant. The transformer exhibits a typical insertion loss of 1.0 dB, amplitude unbalance of 0.3 dB, and phase unbalance of 6° within specified bands. It supports an operating temperature range of -40°C to +85°C, a maximum RF power of 0.25 W, and a DC current limit of 30 mA. Return loss exceeds 20 dB typically across the band.
