ISELIN, NJ — (Marketwired) — 11/05/15 — TDK Corporation announces a new series of EPCOS SMD push-pull transformers featuring compact dimensions of just 9 mm x 8 mm x 5.7 mm. Windings with center taps are located on both the primary and secondary side. The series comprises five types with different transformation ratios ranging between 1:1 and 1:3.8. This enables voltage ratios of 5 V to 5 V or 3.3 V to 12 V to be implemented. Depending on the type, the inductance values of the primary winding are between 9.5 µH and 94 µH.
The transformers of the new B82805* series are designed for a typical switching frequency of 250 kHz and operating temperature range of between -25 degrees C and +125 degrees C. The RoHS- compatible components are suitable, for example, for smaller switched-mode power supplies using push-pull technology and for electrical isolation in industrial automation and process engineering applications.
