Distinguishing features of К52 capacitor series.

     Among capacitors with oxide dielectric (ionistors excluded) this capacitor series is known for the highest specific charge, high value of minimum operating time (5,000 hours at +85 °C; 20,000 hours at +60 °C), low leakage current, wide range of working temperatures (from -60 °С up to +85 °С or +125 °С, depending on capacitor design and tantalum powder grade), higher reliability. The capacitors are used in special devices, applied in rugged environment where stable electric characteristics are required. The capacitors are available in military and specialized military series.

K52-18 type is a high capacity, small size, polar, wet-slug, fixed capacitor. The type has a sealed, all tantalum case. Working temperature range: from -60 °С to +125 °С. K52-18 type is designed for use in special devices, where higher reliability is required. Reduced case sizes and mass allow using of these capacitors in aeronautic and space engineering. K52-18 type is available in military series.
Precautions.
     In K52-18 type the solution of sulfuric acid is used as an electrolyte; if it contacts the board surface (as a result of the non-compliance with manual), short circuit can occur.

К52-19 type. These products are notable for availability of high-voltage group (up to 200 V) and high capacity values. Use of these capacitors allows increasing energy supply, functionalities of spaceship brain units.
