Epcos - Space-saving transformer protection modules for DSL systems
Submitted by nestorb on Tue, 2006-08-01 23:09. A combination of the newly developed rectangular PTC and a modified standard filter choke permits both functional units to be stacked on top of each other, thus halving the space requirement compared with the discrete solution. Some 100mm2 are saved for each TP module, which corresponds to 72cm2 for the new line cards...
