系列：FKP02 MKS02

WIMA plastic film capacitors in PCM 2.5 mm are available in metallized, self-healing version WIMA MKS 02 or in pulse duty film and foil version WIMA FKP 02. As a dielectric, Polyester or Polypropylene is used. The capacitance range includes values of 100 pF through 1.0 µF and voltage ratings of 50 VDC, 63 VDC, 100 VDC, 250 VDC and 400 VDC.

The realization of the smallest plastic film capacitors in the world has been made possible by the use of ultra-thin plastic film in thicknesses of 0.8 µm and below. The film processing with highly sensitive machines requires a high degree of experience and technical know-how.

The WIMA series with 2.5 mm PCM are contacted at the end surfaces and have very low self-inductance due to the small pin spacing of the capacitor and its fully contacted electrodes. Furthermore, the pulse and current loading capacities basically increase, the smaller the PCM can be designed, because - provided that the thickness of the film is the same - a longer band length is needed to achieve a particular capacitance value.

WIMA capacitors in PCM 2.5 mm are outstandingly suitable for HF decoupling in the field of high frequencies and open up new possibilities for use in applications with limited space requirements and high packing density.

PCM 2.5mm的WIMA塑料薄膜电容器有金属化、自愈型WIMA MKS 02或脉冲占空比薄膜和箔型WIMA FKP 02。作为电介质，使用聚酯或聚丙烯。电容范围包括100 pF到1.0μF的值和50 VDC、63 VDC、100 VDC、250 VDC和400 VDC的额定电压。

利用厚度在0.8微米及以下的超薄塑料薄膜，实现了世界上最小的塑料薄膜电容器。使用高灵敏度机器进行胶片处理需要高度的经验和技术诀窍。

具有2.5mm PCM的WIMA系列在端面接触，由于电容器及其全接触电极的引脚间距小，自感系数很低。此外，脉冲和电流负载能力基本上增加，可以设计更小的PCM，因为-如果薄膜厚度相同-需要更长的频带长度来实现特定的电容值。

PCM 2.5mm中的WIMA电容器非常适合高频领域的高频去耦，为在空间要求有限、封装密度高的应用中使用开辟了新的可能性。

系列：FKS2 FKP2 FKS3 FKP3

In the case of film and foil types, the electrode is not applied as for the metallized capacitors, but is wound with the dielectric as a metal foil. Due to their lower series resistance, the components produced this way have excellent pulse and current carrying capability, as well as a very high insulation resistance.

The film/foil construction is mainly used for capacitors with smaller capacitance value. The advantage of this construction principle is the easy contactability of the metal foil electrodes and the good pulse strength. To avoid breakdowns caused by weak spots in the dielectric, the insulating film chosen is always thicker than theoretically required by the values which are determined from the specific breakdown strength of the material.

WIMA film/foil capacitors in PCM 5 mm to 15 mm are available in two dielectric versions. WIMA capacitors with a Polyester dielectric (PET) are suitable for general applications such as coupling, decoupling and by-passing. Polypropylene capacitors (PP) are used in the high frequency field. This includes resonant circuits, power supplies, deflection circuits, oscillator circuits and audio equipment.

WIMA film/foil capacitors in PCM 5 mm to 15 mm are available with capacitance values from 33 pF to 0.22 µF and rated voltages from 63 VDC to 1000 VDC.

系列：MKS2 MKP2 MKS4 MKP4C MKP4

In the case of metallized capacitors, thin layers of aluminium (approx. 0.03 µm) are vacuum-deposited on the insulating film as conducting electrodes. In the case of a breakdown, the short circuit current causes the thin metal coating to evaporate around the point of failure and an insulating area is formed. The capacitor remains intact (self-healing). Due to their construction principle metallized capacitors stand out for their very favourable capacitance/volume ratio.

Metallized WIMA capacitors in PCM 5 mm - 52.5 mm are available in two dielectric versions. Capacitors with a Polyester dielectric (PET) are suitable for general applications such as coupling, decoupling and by-passing. By making use of ultra thin film and appropriate manufacturing experience, it has been possible to achieve high capacitance values in very small box sizes. Polypropylene capacitors (PP) are used in the high frequency field. This includes resonant circuits, power supplies, deflection circuits, oscillator circuits and audio equipment.

Upon customer request, larger box sizes can be supplied in 4-pin versions. Types with terminating plates can also be manufactured on request. The advantage of this method of construction, besides the improved mechanical stability of the component on the board, is the excellent electrical contact reliability.

系列：MKP10 FKP1

The construction principle of the series WIMA MKP 10 consists of a non-metallized dielectric film and an carrier film metallized on both sides acting as electrode. Thanks to the metallization on both sides, the electrical conductivity is considerably improved and the contact surface between the electrodes and the schoopage layer is doubled. This results in better contact and allows for high current and pulse loading capability. The properties of metallized capacitors such as excellent self-healing and high volume capacitance remain unchanged.

The WIMA FKP 1 series was developed for extremly high pulse loads. It has an internal series connection, the metal foil electrodes being combined with a floating electrode metallized on both sides. The metal foil electrodes are safely contacted on both sides of the end surfaces. At the same time the capacitor is fully self-healing due to the floating electrode metallized on both sides. As regards pulse loading capability, WIMA FKP 1 represents the high-end of capacitor technology.

WIMA pulse capacitors are suitable for high pulse and high frequency applications in e.g. switch mode power supplies, TV and monitor sets, lighting industry, audio/video equipment, converters in drives and power electronics or in electronic ballasts. They are available with capacitances from 100 pF through 47 µF and with voltage ratings from 100 VDC through 6000 VDC.

系列：DC LINK MKP3  DC LINK MKP4 

WIMA DC-Link 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. Manufactured with a low loss polypropylene dielectric they show a higher current carrying capability as well as lower dissipation/self-heating at high frequencies compared to electrolytic capacitors. Further outstanding features are, e.g.:

系列：MKP-X2 MKP-X1R MKP-Y2 MP3-X2 MP3-X1 MP3-Y2/3R-Y2

Radio interference suppression capacitors must not only satisfy EMC requirements in suppressing outgoing interference from an application but they must also protect the application from incoming power surges. Hence careful selection of these components is essential.

The special feature of WIMA Polypropylene RFI capacitors are the high capacitance values at smaller case sizes compared to metallized paper capacitors, being available up to 10 µF with AC voltages of 300 VAC, 305 VAC and 440 VAC for class X1, X2 and Y2. Based on the dielectric used they are highly cost-effective.

WIMA metallized paper are neither actively nor passively flammable. The components are resin impregnated under vacuum and encapsulated with self-extinguishing cast resin. Thanks to the good oxidation behaviour of the paper dielectric, they have outstanding self-healing properties even with high energy pulses. The capacitors are specified for temperatures up to 110° C and are available for class X1, X2 and Y2 applications.

Class X capacitors are connected between phase and neutral or phase and phase conductors. Class Y capacitors have an increased degree of electrical and mechanical safety and are connected, for example, between phase conductors and earthed casing, and thus by-pass operating insulation.

系列：SNUBBER MKP SNUBBER FKP 

Development of the WIMA Snubber MKP and WIMA Snubber FKP capacitor series for high power conversion is based on decades of experience with Polypropylene pulse capacitors.

WIMA Snubber capacitors are available both as double-sided metallized pulse version - WIMA Snubber MKP - and for extremly high pulse ratings in self-healing film/foil technology - WIMA Snubber FKP. Their electrical performance as well as the manifold number of available connecting options makes the WIMA Snubber technology unique:

系列：GTO MKP

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 with a dielectric of metallized polypropylene film and encapsulated in a cylindrical plastic case sealed with self-extinguishing polyurethane resin. Their construction creates outstanding features, e.g.:
