Universal multiwinding transformers

трансформаторыTDK 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:
  • Initial DC/DC power circuit check
  • Digital home appliances
  • POL(Point of Load) DC/DC converters
Due to universal design PCA series transformers have different winding turns number ratio. For example, the company offers several technical constructions, particularly, 4 size types (11/5ER, PCA14.5/6ER, 15EFD, 20EFD) and 6 variants of windings and also a wide range of inductance for each design taking onto account a possible application. The temperature range is from -40 to +85°С.
Main characteristics of transformers produced by TDK are represented in the table:
