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.

Reduction of conducted Noise with external Capacitor
In order to meet conducted emissions EN55022-A and EN55011-A a capacitor at the input side of triple output models
and B-version models has to be installed.
Note:
+Vin
The value of C1 is between 1µF and 10 µF,
depending on the load
For 24V input models use 50V capacitor.
For 48V input models use 100V capacitor.
