TDK Corporation presents 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 5V to 5V or 3.3V to 12V to be implemented. Depending on the type, the inductance values of the primary winding are between 9.5µH and 94µH.
The transformers of the new B82805 series are designed for a typical switching frequency of 250kHz and operating temperature range of between -25 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.
Main applications are expected to include: Switch-mode power supplies using push-pull technology and Electrical isolation in industrial automation and process engineering. Main features and benefits: Compact dimensions of just 9 mm x 8 mm x 5.7 mm; Five types with different transformation ratios for common voltages in industrial applications; and Typical switching frequency 250kHz.
