Development of the new series is complete. We are now accepting preliminary orders for capacitors.
Delivery dates: First and second quarters of 2026.
We also accept orders for capacitor samples in agreed-upon quantities.

Polar, fixed capacitors type K53-84 are designed for surface mounting in direct current, ripple current and pulse current circuits. Manufactured in climatic class B3.1 in accordance with GOST 15150 (for use in rooms that are heated irregularly).
