The TCM1-43X+ is a surface-mount 1:1 core and wire RF transformer (balun) designed for wideband performance from 10 to 4000 MHz. It features low insertion loss, typically 1.1 dB, and excellent return loss. The component is constructed on an aqueous washable plastic base with solder-plated leads. It includes a top-hat feature for visual identification and automated pick-and-place assembly. This transformer is suitable for applications such as PCS, wideband push-pull amplifiers, and cellular communication systems.
