CMP High-Voltage Capacitors

TYPE CMP CAPACITORS offer superior electrical characteristics, coupled with small size and are designed to meet or exceed the requirements of MIL-C-19978/3E.

TYPE CMP CAPACITORS are designed for a wide range of uses including filter, bypass, and coupling applications in the low audio frequency range, energy storage, laser discharge, power factor correction, etc. The CQ72 style case and internal construction permit operation in any position. Glazed ceramic bushings are used, and, in the voltage ranges of 2 kVDC and greater, ceramic is the insulation in the terminal assembly. The threaded stud terminal is supplied with a nut, lockwasher, and/or solder lug. The entire assembly is hermetically sealed.

SIZE: The case sizes listed are not necessarily the smallest possible for a given capacitor. If size and shape are critical to your application, Chicago Condenser Corporation will be pleased to work with you to optimize a capacitor to your needs. Wide range of case sizes in several styles available. A revised design which employs stock material may result in little additional cost. If a custom case is required, cost may depend heavily on quantity.

IMPREGNANT: CMP capacitors are premium products impregnated with silicone dielectric fluid, which is about ten times more expensive than high grade mineral oil. The use of mineral oil in CMP designs results in substantial cost reductions, at the expense of operating temperature range and flammability. Should your design allow use of mineral oil impregnant, Chicago Condenser Corporation will be pleased to quote on a mineral oil impregnated design.

CONTAINER: At the highest voltages, the large ceramic terminals required become a substantial portion of materials costs. Capacitor cost can be reduced by either specifying only one terminal (with the other grounded to the case) or one terminal rated for the full voltage with the other rated for a much lower voltage (for example, when one terminal will be connected to neutral). While CMP capacitors can be fabricated to any voltage level, above 50 KV, Chicago Condenser Corporation’s BAM capacitors tend to be much more cost effective. These capacitors are fabricated in an insulating tubular container with terminals at each end. The case, therefore, becomes the insulation between the terminals. For Further details, see Chicago Condenser Corporation’s BAM catalog.

WINDING DESIGN: Capacitors can be constructed in a range of winding designs (e.g., extended foil, tab constructions, etc.) and can be fabricated from a wide range of dielectric materials including polypropylene, polyester (“Mylar”), polycarbonate, etc. with varying layers and configurations of paper. Each combination of construction and materials has its advantages and disadvantages. For example, an extended foil design gives the greatest current carrying capability and lowest ESR at the expense of a somewhat higher inductance that can be achieved with a tab design. The inductance and ESR in tab designs depends on the number of tabs. Increasing the number of tabs in a winding increases the time required in manufacture, and therefore, the cost to the customer. Mylar is a good general purpose dielectric with a relatively high dielectric constant which results in a smaller capacitor that polypropylene; however, polypropylene has much better high frequency characteristics. The proper use of fluid-impregnated paper layers is important in capacitors which see frequent and wide swings in voltage (AC, pulse discharge, etc.), as it can provide a “self-healing” medium with greater tolerance to electron injection in highly stressed regions of the capacitor.
