Tervakoski Film ECU
Performance
like never before
After almost 200,000 hours of testing, we are proud to present the Tervakoski Film ECU. The new capacitor film stands strong even at 135 °C, enabling new horizons for the most demanding solutions such as e-mobility and sustainable energy. Tervakoski Film ECU makes it possible to unleash the full potential of the new generation power semiconductors.
ECU film’s manufacturing material Stelora™ is produced using renewable feedstock. The unique properties of Stelora™ and high quality film manufacturing process provides the Tervakoski Film ECU with an advanced performance.

Performance
The film has superior electrical properties at high temperatures. It’s also stronger and performs better thanks to material’s high purity.

Durability
Exceptional heat resistance means less degradation and less space required for cooling. That means the products will have a longer lifespan and they can be smaller and more energy efficient.

Versatility
Bridging the gap between conventional polymers and high-temperature plastics, ECU film is suitable for a wide range of technically advanced applications.
Technical features of the Tervakoski Film ECU
Our R&D engineers have recently conducted rigorous performance testing on our latest development, the ultra-high temperature Tervakoski Film ECU. This white paper document summarises the test results from a comparison of the ECU film and state-of-the-art BOPP capacitor film (ECT).
