WIMA SMD Film Capacitors

WIMA SMD capacitors in size codes 1812 to 6054 are available with capacitance values from 0.01 µF to 6.8 µF and voltage ranges from 63 VDC to 1000 VDC. Produced with the proven box technology they shows following advantages in comparison with non-encapsulated or moulded SMD capacitor versions:

• No internal cracks or delamination
• ∆C/C over temperature very low (SMD-PET, SMD-PEN) or extreme low (SMD-PPS)
• Self-healing capability results in high withstanding voltage and high reliability.

WIMA Film Capacitors in PCM 2.5 mm

The smallest boxed film capacitors in the world are available in metallized, self-healing version WIMA MKS 02 or in pulse duty film and foil version WIMA FKP 02. Capacitors in PCM 2.5 mm are outstandingly suitable for HF decoupling in the field of high frequencies and for use in applications with limited space requirements. Features:

• Dielectric: Polyester (PET) or Polypropylene (PP)
• Capacitances: 100 pF to 1.0 µF
• Voltage ratings: 50 VDC, 63 VDC, 100 VDC, 250 VDC and 400 VDC.

WIMA Pulse Duty, Self-Healing Film Capacitors

The WIMA FKP 1 series combine the high pulse load capability of Film/Foil capacitors with the excellent self-healing properties and high volume/capacitance ratio of metallized film capacitors. As regards pulse loading capability, WIMA FKP 1 represents the high-end of capacitor technology. Advantages:

• Extremely high pulse and current rating
• Self-healing capability results in high withstanding voltage and outstanding reliability
• Rated voltages up to 6000 VDC and capacitances up to 4.7 µF.

WIMA GTO Capacitors in Cylindrical Case

WIMA GTO MKP capacitors are especially designed to attenuate voltage spikes on GTO (Gate-Turn-Off) Thyristors and IGBT (Insulated Gate Bipolar Transistor). They are manufactured in dry-type technology and encapsulated in a cylindrical plastic case sealed with self-extinguishing polyurethane resin. Advantages:

• High pulse reliability and high rms current carrying capability
• Almost unlimited life expectancy due to excellent self-healing properties
• High shock and vibration resistance due to outstanding mechanical stability.

WIMA DC-LINK Capacitors up to 4920 Microfarad

WIMA DC-LINK MKP 6 capacitors are especially designed for applications in high power converter technology where due to increasing electrical requirements they are more and more substituting electrolytic capacitors. They have a cylindrical aluminium case with M6 screw terminations and M12 screw bolt for bus bar mounting. Features:

• Capacitances: 75 µF to 4920 µF
• Rated voltages: 600 VDC to 1500 VDC
• Construction: non-polar, dry construction without electrolyte or oil.
