Home>Environmental Activities>Development of Smaller Highly Efficient Power
When we develop new products, we conduct their environment assessment from the standpoints of energy-saving, recyclability, use or non-use of toxic substances and environmental friendliness of packing materials to develop more environmentally friendly products.
All our new products are RoHS-compliant from their release date.

One of the concepts for our new series is "smaller." We have taken a variety of measures such as development of low loss transformers and synchronous rectifiers. As a result of these measures, much smaller highly efficient power supplies are born. We were able to achieve half the size in area of our existing products.
