Recom R1SE Series 1 W DC/DC SMD converters

The Recom R1SE Series, with 1 W of power, 1000 VDC isolation and 5 V input/output, is a part of the economical E-class. These converters are mainly used to provide isolation for the interfaces of bus systems. In these applications, operating temperatures of +85°C without de-rating are sufficient. This makes the use of high-grade temperature components with specifications up to +100°C, as used in the standard products, unnecessary. This helps to drive down both the material costs and the costly and time-consuming certifications which are no longer necessary.

The case, measuring only 12.75 x 10.7 x 6.7 mm and consisting of two parts, has been designed so that potting is not necessary; thereby further reducing the material costs. Weighing 1 g, this 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.
