Introduction

Film capacitors, also called plastic film capacitors, are non-polarized electrolytic capacitors, which are made from thin layers of metal foil or a polymer film. They are widely used in electronic circuits such as adjustable capacitors, DC-blocking capacitors, impedance matching capacitors, frequency determination capacitors, transient protection capacitors, coupling capacitors, stabilizing capacitors, signal bypass capacitors, and voltage-dividing capacitors. In particular, the MKT1820415636 is a classic film capacitor with a unique application field and working principle.

Application Field

The MKT1820415636 film capacitor is a high-quality, dielectric type, radial electric double layer Ultra-Capacitor (ULTEM) dielectric film capacitors. It is especially suitable for use under extreme working conditions with long-term stability and reliability. The series is very popular for applications in the filed of automotive industry, telecom switching systems electrical power systems, consumer electronics, etc. It allows for direct mount to the PC board. By using the latest technologies and proprietary design techniques, this capacitor has high resistivity, low loss and high frequency performance.

Working Principle

The MKT1820415636 series utilizes an innovative technology called "electric double layer capacitance" or EDLC for short. This EDLC is an electrical double-layer where the two conducting layers are insulated from each other by a dielectric material. When the dielectric material is subject to an electric field, it develops an electric double layer of charge at the surfaces of the dielectric material. The total charge stored in the double layer is proportional to the applied electric field. The EDLC technology employed in this film capacitor ensures high reliability over long periods of operation at high temperatures. This technology also allows for a stable temperature coefficient, significant ripple noise reduction and increased current handling capability. In addition, the series features low leakage current and low equivalent series resistance (ESR).
