The company says improved thermal performance helps extend component and system life by minimising thermal stress, while also allowing designers to increase power density in compact layouts. The RMWA demonstrates excellent stability under AEC-Q200 testing, including load life, temperature cycling, biased humidity, and short-time overload. Anti-sulfur construction further ensures reliable operation in polluted or corrosive environments.

Defined pulse voltage and pulse power characteristics simplify circuit design, enabling more predictable performance in applications subject to transient loads.

These capabilities make the RMWA well-suited for automotive electronics, where long-term reliability and thermal performance are critical; high power gate drivers, where pulse handling supports switching stability; industrial controls exposed to harsh environments; power supplies requiring higher power density; and high reliability consumer devices demanding consistent long-term performance.
