The series of high class capacitors for high voltage circuits. This series was being developed especially for laser devices. But it was also successfully applied in high voltage electronics, partucularly, in Marxgenerators, capacitance dividers.
The construction of such capacitors is performed on the silver plates with dielectric with SrTiO3 "screw' terminals make the mounting easier and allows to create capacitors blocks for high voltage circuits. Epoxy capacitor coating (epoxy resin) provides the stability to breakups. It's very important in many application fields.
Features
- small sizes
- Dissipation factor(tanδ)
- Perfect voltage-capacity characteristics
- Screw terminals make the mounting more comfortable and reliable
- Hermetical dielectric coating
