Sales point (English)
Struggling with selecting switching (flyback) transformers for your LLC resonant power circuits?
◆ Large variation in transformer leakage inductance
◆ Wide fluctuation in magnetizing inductance
◆ Inconsistent output under heavy load
◆ Long lead time for custom transformers requiring gapped core processing
◆ Unstable characteristics of transformers with gapped cores

Musashino Tsuko has the expertise to solve these challenges!
★ We developed our own automatic ferrite core grinding machine to perform high-precision gap processing—achieving tight control over inductance tolerance.
★ Our proprietary winding methods allow us to commit to your specified values for leakage inductance, magnetizing inductance, and switching frequency—with low tolerance.
★ In-house core processing eliminates dependence on external suppliers, enabling fast prototype delivery.
★ We keep a wide range of custom winding materials in stock—including litz wire and copper foil—for quick turnaround from prototyping to delivery.

Size / capacity (English)	◎ We design and develop custom transformers ideal for LLC converters that meet all these technical demands. ◎ Customization available for various sizes (EER9.5 to PQ100), power ratings, and frequency ranges. If you have any questions, please feel free to contact us.
