High voltage multilayer ceramic capacitors designed by EXXELIA are adapt-

ed to applications in electronics such as high voltage power supplies and high

circuits. Their multilayer construction offers significant size and space sav-

ing advantages. They are available in class 1 (NPO), class 2 (X7R) and C4xx

(–2,200 ppm/°C) dielectrics versions complying with the main requirements

of applicable standards. They are suited for use in commercial, industrial and

High-Rel military and space circuits.

As standard products can’t meet all the specificities of all applications, special

applications may require specific features (higher voltage, burn-in, dimensions,

coating, leading, marking…) not described in this catalogue. Based on our

state-of-the-art technologies and our expertise, our Engineers may study at

your request all special components to meet your application.

Please, consult us for more information.

NPO/COG DIELECTRICS (CLASS 1)

Made of titanium oxide and other various selected oxides, they feature unique

stability of all parameters under such constraints as operating time, tempera-

ture, voltage applied. For example, the quality factor remains very high over an

extremely wide frequency range. As example, loss angle tangent value at 1MHz

is typically in the order of 3.10-4. These characteristics make them compatible

with steep-edge impulse mode without noticeable temperature rise. The differ-

ent parameters and related variations are illustrated in figures below:
