These are suitable for use in medical equipment with previously offered current ratings of 3A-15A and are suitable for medical applications with increased current ratings that require minimal leakage current.

Understanding RFI Power Line Filters

What Is a Power Line Interference Filter?

A power Line interference filter is a primary tool available to the designer of electronic equipment to control conducted RFI both into the equipment (potential equipment malfunction) and out of the equipment….

Since the largest component of leakage current is usually from the power line filter, it is prudent to set a maximum leakage current limit for the filter itself……..

Kemet Corporation – Capacitor Technologies

KEMET’s product line includes surface-mount capacitors in aluminum, ceramic and tantalum and leaded capacitors in ceramic and tantalum.

Kemet Corporation – Capacitor Technologies

Broad selection of capacitor technologies in the industry across all dielectrics, along with an expanding range of electromechanical devices, electromagnetic compatibility solutions and super capacitors.

The name “KEMET” is a blend of the words “chemical” and “metallurgy.”

“…..Fortunately for KEMET, Bell Laboratories had also invented the solid tantalum capacitor, which complemented the use of low-voltage transistors (semi-conductors) in electrical circuits. Since Union Carbide had experience in the fields of high-temperature metals and alloys, the solid tantalum capacitor was chosen as KEMET’s “new product”.

Kemet High Voltage C0G FT-CAP

High Voltage C0G FT-CAP

The HV C0G FT-CAP is ideal for a broad range of high voltage applications in which high volumetric efficiency and resistance to thermal and board stress are critical.

It offers low leakage current, exhibits low ESR at high frequencies and finds conventional use as snubbers or filters in applications such as switching power supplies and lighting ballasts. Their exceptional performance at high frequencies has made them a preferred choice of design engineers worldwide.
