EVOX RIFA – KEMET

Evox Rifa
Evox Rifa Group Oyj manufactures passive electronic components, specializing in plastic film, paper and electrolytic capacitors. Their major customer groups are in industrial, automotive and consumer electronics and the lighting industry. Evox Rifa’s strength lies in the design and production of customized products that require specialist expertise. Evox Rifa, with headquarters in Finland, has a worldwide sales and distribution network. Its production plants are located in Indonesia, Great Britain, China, Sweden and Finland. Evox Rifa has two global business areas: Electrolytic Capacitors and Film and Paper Capacitors.

Evox Rifa primarily focuses on the production of capacitors, which are essential electronic components used for storing and releasing electrical energy. Their capacitor portfolio includes a variety of capacitor types, such as film capacitors, electrolytic capacitors, and power capacitors. A capacitor used for smoothing, energy storage or filtering of a rectified AC voltage will be loaded with an AC ripple current causing a power loss and heating of the capacitor. The quality of Evox Rifa’s products and services is based on a continuous strive towards excellency throughout the whole organization. Skilled and motivated personnel, technical know how and modern equipment combined with extensive quality assurance make Evox Rifa the supplier of components of the highest quality.

  1. Film Capacitors: Evox Rifa is particularly well-known for its film capacitors. These capacitors are widely used for applications that require high reliability, long life, and excellent electrical performance. Film capacitors are commonly used in power electronics, lighting, motor drives, and more.

  2. Electrolytic Capacitors: Evox Rifa also produces electrolytic capacitors, which are often used in applications where high capacitance values are needed, such as power supplies and audio equipment. Aluminium Electrolytic capacitors manufactured for use in d.c. applications contain an anode foil and a cathode foil. As such they are polarised devices and must be connected with the +ve to the anode foil and the -ve to the cathode foil. If this were to be reversed then the electrolytic process that took place in forming the oxide layer on the anode would be recreated in trying to form an oxide layer on the cathode. In forming the cathode foil in this way heat would be generated and gas given off within the capacitor usually leading to catastrophic failure.
