Belleta® iEA Series DC/DC Power Modules
48V Input, 25A Output
Eighth Brick
The Belleta Series offers an industry standard
eighth brick power module with true useable
power. Thanks to its low component count and
single-board open-frame design, it provides both
better electrical and thermal performance, and
lower cost than many other suppliers’ eighth brick
product offerings. Belleta® modules are perfect
for both next generation planning and cost
reduction design environments

top view
Both the thermal curves provided and the example given above are based upon measurements made in TDK Innoveta’s
experimental test setup that is described in the Thermal Management section. Due to the large number of variables in
system design, TDK Innoveta recommends that the user verify the module’s thermal performance in the end application.
The critical component should be thermo coupled and monitored, and should not exceed the temperature limit specified in
the derating curve above. It is critical that the thermocouple be mounted in a manner that gives direct thermal contact or
significant measurement errors may result. TDK Innoveta can provide modules with a thermocouple pre-mounted to the
critical component for system verification tests.
