TDK is one of the world's leaders on coils developing and manufacturing. The company draws special attention to ipmrovement and expanding of goods range. The main accent is set by TDK's developers on the creation of miniature components, which are characterized by improved parameters and advanced functionality. In such a case, multiwinding transformers for general purpose (PCA series) produced by TDK are of a great interest.
A distinguished feature of PCA series is their universal usage in digital devices and home appliance equipment. As most commonly, these components are applied in:
Main characteristics of transformers produced by TDK are represented in the table:
- Initial DC/DC power circuit check
- Digital home appliances
- POL(Point of Load) DC/DC converters
