Are intended for work in chains of direct, pulsating currents and in a pulsed mode. They are manufactured in climatic version B (non-insulated) and UHL (insulated and non-insulated).

A feature of these capacitors is the presence of high-voltage ratings with a voltage of 400 and 450 V, a high value of the minimum operating time (more than 10,000 hours at a temperature of 60°C). They are used in converter technology, secondary power supplies, in general and special-purpose products.
