The WMF1D68K is a polypropylene film capacitor offering a high level of reliability and durability; it has a voltage rating of 160VAC.

Applications

The relatively high capacitance values attained by WMF1D68K capacitors allow them to operate in a variety of applications. These capacitors are commonly used in DC-DC converters to smooth out the output voltage. The WMF1D68K is also well suited for use in high-frequency switching power supplies, EMI filter designs, frequency converters, and power factor correction circuits. This capacitor is suitable for applications in home appliances, office equipment, power tools, lighting fixtures, and automotive systems.

Working Principle

The WMF1D68K is based on the same principle as most capacitors: a material (in this case a thin plastic film) that is insulated on both outer faces, and sandwiched between two metal layers (tin-plated nickel-copper alloy). When a voltage is applied to the WMF1D68K capacitor, it stores electrical energy in its mechanical structure; which is due to the voltage-induced mechanical forces causing the film to bend. This in turn causes an electric field to form across the film, resulting in an electrical charge being stored.

Advantages

Film capacitors offer certain advantages over other types of capacitors. Firstly, they have an excellent power-handling capability, making them particularly suited to use with fast-switching power supplies. Secondly, their construction makes them highly durable; they are typically able to withstand far higher voltages than most other capacitors without any physical degradation. This makes them an excellent choice for high-power applications.

Conclusion

The WMF1D68K is a film capacitor designed for a wide range of applications, offering excellent power-handling and reliability. Its durability and ability to store electrical energy makes this capacitor suitable for use in various applications such as DC-DC converters, high-frequency switching power supplies, EMI filter designs, frequency converters, and power factor correction circuits. The WMF1D68K is well-suited for use in home appliances, office equipment, power tools, lighting fixtures, and automotive systems.
