HHM1589E1

Balun Overview

The TDK HHM1589E1 is a multilayer ceramic balun transformer designed for RF signal conditioning. It operates within a frequency range of 350MHz to 470MHz, supporting impedance conversion between 50 Ohms and 200 Ohms. The component utilizes an SMD/SMT mounting style in a compact 0805 (2012 Metric) package, measuring 2.00mm x 1.25mm x 0.95mm. It features a typical insertion loss of 1 dB and functions reliably across an operating temperature range of -40°C to +85°C.
