The ER14.5/6 flexible transformer is a compact, high-frequency magnetic component designed for DC/DC converter applications. It is particularly suitable for modular power designs where flexibility in winding configuration and circuit topology is required.
A defining feature of the ER14.5/6 transformer is its six identical windings, which can be freely configured in series or parallel combinations to meet various voltage and current requirements.
Symmetrical winding design ensures balanced electrical performance
Supports multiple turns ratio configurations through external connections
Enables versatile circuit implementation without redesigning magnetics
This flexible architecture allows a single transformer model to cover a wide range of applications and power levels.
The ER14.5/6 transformer is engineered for reliable operation across a wide temperature range:
Operating temperature range typically from –40°C to +125°C
High-quality insulation system ensures electrical safety
Robust structure supports long-term reliability in continuous operation
Its thermal resilience makes it suitable for industrial and harsh environment applications.
DC/DC converter modules
Distributed power systems
Telecom and networking equipment
Industrial control power supplies
Automotive and EV auxiliary power systems
