RECOM unveil R1SE series of low cost 1 watt SMD DC-DC converters

The R1SE Series, with 1 watt 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 +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 has helped to drive down both the material costs and the costly and time consuming certifications which are no longer necessary.

The case, measuring only 12.75 x 10.7 x 6.7mm and consisting of two parts, has been designed so that potting is not necessary - further reducing the material cost. Weighing only 1 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 process.

These modifications have resulted in a 30% price advantage compared to the standard products with no compromises to quality. The R1SE is subjected to the same rigorous RECOM quality checks as the standard part series and carries the same 3 year warranty. Priced around £1.40 for production quantities the R1SE series is an economic alternative to discreet in-house designs. Samples are available from Dengrove Electronic Components.
