Recom – Cost-efficient converters provide isolation for the bus system interfacesSep 13 2012 - Power [More Power Articles]
With two newly established SMT lines in Taiwan, Recom has refined the design and manufacturing process to produce even more cost-effective versions of specially selected DC-DC converters in batches of 100.000 or more.
The R1SE Series, with 1W of power, 1000VDC isolation and 5V input/output, is the first release in the new economical ‘E-class’. These converters are mainly used to provide isolation for the interfaces of bus systems. In these applications, operating temperatures of +85C without de-rating are sufficient. This makes the use of high grade temperature components with specifications up to +100C, as used in the standard products, unnecessary. This helped to drive down both the material costs and the costly and time consuming certifications which are no longer necessary.
The case, measuring only 12,75mm x 10,7mm x 6,7mm and consisting of two parts, has been designed so that potting is not necessary – further reducing the material cost. Weighing only one gram this lightweight component can be positioned quickly and precisely with automatic placement equipment. Despite not being potted, the 100% lead-free design enables it to withstand all thermal cycling in the vapour-phase solder processes.
These modifications have resulted in a 30% price advantage compared to the standard products with no compromises to quality, says the company.More news from Recom International
