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.
