Leave the design and manufacturing of high-frequency power supply transformers (step-up/down, etc.) to us. We will manufacture efficient custom transformers domestically.

Our company designs and manufactures various types of small high-frequency transformers (RoHS compliant), starting with switching power supplies, at our domestic factory. We adopt a custom-made system that considers the shape, size, circuit method, wire material, thickness, etc., of the transformer from scratch based on the customer's requirements, allowing us to produce transformers that are optimal for our customers' products. The engineers who design and manufacture the transformers are specialists in transformers. In addition to their extensive knowledge and experience, they skillfully use various digital tools to create high-quality transformers from both analog and digital perspectives. Furthermore, since we have insights into electronic circuits, we can design transformers with consideration for surrounding circuit configurations upon request, producing stable transformers that take into account factors such as "heat generation and magnetic saturation." We also accept design and manufacturing requests for challenging tasks such as miniaturization and high voltage applications. If there is a high risk of heat generation based on your requirements, we respond flexibly by proposing appropriate specifications. If you need new transformers for product development (prototyping) or improvements to existing products, please feel free to contact us. We will deliver the optimal transformer for your products.
