Product Brief: Belleta® iPB Series – Surface Mount PicoBrick
Belleta® iPB Series DC/DC Power Modules
48V Input, 10A Output
Surface Mount PicoBrick
The Belleta Series offers a 35W PicoBrick power module in the
industry’s smallest 10A footprint that is 33% smaller than an
industry standard eighth brick and power pin compatible with an
existing industry standard footprint. The Belleta Series eliminates
the need to use highly derated eighth or quarter brick power
modules, thereby optimizing board space utilization and cost. As
with other modules in the Belleta series, a low component count
results in a low cost, high performance design. The low weight,
surface mount design is well suited for almost any manufacturing
environment.
