HHM1589D1

Balun Overview

The HHM1589D1 is a multilayer balun converter manufactured by TDK Corporation, designed for RF applications within the 350MHz to 950MHz frequency range. It provides impedance transformation between 50 ohms and 200 ohms. The component utilizes an 0805 (2012 metric) surface-mount package with six PCB pads. This device facilitates balanced-to-unbalanced signal conversion in compact electronic designs.
