The TAM series is a range of high performance 25W DC/DCconverters with very high power density. They provide a cost effective solution in industrial, datacommunication and telecom applications with limited space on PCB. These converters are built in SMT-hybrid technology on a ceramic substrate which together with a metal case provide a very good heat dissipation. No additional heatsink is necessary for operating temperature up to +75 °C (resp. +85°C) at full load.
