TRANSFORMER DESIGN

Our Transformers vertical is backed by designers with many years of experience, and the designers are supported by our Sourcing & Design (S&D) team — for identifying optimal material sources right at the design stage.

We use tools such as MathCAD, Ansys, Maxwell and Solidworks FEA.

SIGNAL TRANSFORMERS

Our Signal Transformers include Miniature Audio Transformers, Gate Drive Transformers and SCOT-T Transformers. These transformers are used for step-up / step-down, isolating, providing feedback, signal and, impedance matching.

MINIATURE AUDIO TRANSFORMER

Our Miniature Audio Transformers are used in RF/Audio communication equipment and also Generator Control Units. High Common Mode Rejection Ratio and low Insertion Loss are our key features of our Miniature Audio Transformer. We can offer design variations and different layouts based on customer requirements.
