Improved power quality: Ensures more reliable and consistent power electronic device operation. The Department of Energy (DOE) objectives for traction inverters are reducing cost and increasing efficiency. High temperature electronics eliminate the separate cooling system and devices operate off engine coolant.
Our plastic film capacitors meet stringent quality standards, ensuring reliable performance across various applications. They are designed to operate within a temperature range of -40℃ to +85℃ (up to +105℃ for certain models), and some products, like the MKCP4T, offer enhanced humidity resistance. Additionally, all of our capacitors comply with environmental and safety regulations

Film capacitors are made out of two pieces of plastic film covered with metallic electrodes, wound into a cylindrical shaped winding, with terminals attached, and then encapsulated. In general, film capacitors are not polarized, so the two terminals are interchangeable. There are two different types of plastic film capacitors, made with two different electrode configurations:

EMI suppression capacitors, as the name implies, are used to reduce electromagnetic interfer-ence. They are connected directly to line and are therefore exposed to overvoltages and tran-sients, which could damage the capacitors. For this reason, EMI suppression capacitors must comply with the requirements of the following safety standards:

Metallized film capacitors: Metalized Film Capacitor This device has a dielectric that consists of two metalized films alongside a plastic film. Also, the electrode of this capacitor comes from a thin vacuum-deposited aluminum (about 0.03µm) metallization—that coats one or both sides of the device. Further, when there''s a short circuit between the electrodes, the component may
Sequential stretching process for highest film quality: Optimised surface roughness, good self-healing effect; Simultaneous stretching process: Growing demand for quite special and high-value applications • Low MD shrinkage even at low thickness • Higher potential for thinnest film due to high stretching ratios

The finish of film capacitors is assessed in compliance with EPCOS finish specifications. For more detailed specification, refer to the "General technical information" chapter. When applicable, the individual data sheets are definitive for finishing. The failure rate is defined as the failure percentage divided by a specified operating period.
The dimensional drawings in the individual data sheets are definitive for the dimensions. The finish of film capacitors is assessed in compliance with EPCOS finish specifications. For more detailed specification, refer to the "General technical information" chapter. When applicable, the individual data sheets are definitive for finishing.
The capacitor is a device (part) that performs this charging and discharging of accumulated charges as its function. εr : Relative Permittivity 2. Types of (fixed) capacitors 3. Types of Film Capacitors “Miler” ( Du-Pont) is famous.
Dielectric, electrodes and encapsulation systems are selected to achieve the best performance based on the voltage waveform, current and other environmental parameters. AC film capacitors are typically packaged in metal cans, filled or vacuum impregnated with oil to reduce the occurrence of corona discharge.
In the case of film capacitors, the two most relevant parameters affecting the failure rate are tem-perature and voltage. In the IEC61709:2011 standard, models for stress factors are consequently applied in order to convert the failure rates under reference conditions to values applying for oper-ating conditions.
