HHM1520

Balun Overview

The HHM1520 is a multilayer balun transformer manufactured by TDK Corporation using low-temperature co-fired ceramic (LTCC) technology. Designed for the 2.4GHz wireless LAN and Bluetooth frequency bands, it operates within a range of 729MHz to 2690MHz. The component provides balanced-to-unbalanced signal conversion with impedances of 50 Ohms and 100 Ohms. It features a surface-mount device (SMD/SMT) package in the 0805 (2012 metric) footprint. The device supports an operating temperature range from -40°C to +85°C and is RoHS compliant.
