TAM25-2412

DC/DC Converter TAM 25 Series Features Single-, Dual-, and Triple Output Models Wide 2:1 Input Range Very high Efficiency up to 84% Extended Temp. Range available Internal Filter to meet EN 55022, Class A and FCC Part 15, Level A I/O-Isolation 500VDC (1’500VDC for Triple Output Models) Small Dimensions: Single- and Dual Output Models: 50x50x10.5mm, Triple Output Models: 71x61x10.5mm Remote ON/OFF Shielded Metal Case 2 Year Product Warranty 25 Watt 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.
