Film capacitors are a type of capacitor used in a wide variety of applications. The ECQ-E1335KZ film capacitor is a particularly ubiquitous and reliable variant, and is commonly used in applications such as motor drives and audio frequencies. In this article, we will take a look at the application field and working principle of the ECQ-E1335KZ film capacitor.

The ECQ-E1335KZ is most often used in motor drives, as it is capable of handling the high-frequency components of variable frequency motor drives (VFD). It is also used in soft starters, inverters, and electric welding units. The ECQ-E1335KZ’s high temperature stability and anti-surge characteristics make it well-suited to these types of applications. As well as motor drives, the ECQ-E1335KZ is also widely used in HVAC controls, with its notably stable capacitance even at the low temperatures often encountered in this type of application.

In addition to motor drives and HVAC, the ECQ-E1335KZ is also used in energy storage applications such as super capacitors, as well as in audio frequencies. Its good low-frequency characteristics make it suitable for audio frequency applications, and its low ESR and high ripple current handling capabilities make it well suited to energy storage. The ECQ-E1335KZ is especially well-regarded for its noise-reduction capabilities, making it one of the most commonly chosen capacitors for industrial applications requiring precise and audible sound reproduction.

So what is the working principle of the ECQ-E1335KZ? As with all capacitors, the ECQ-E1335KZ works by storing electric charge between two conductive plates. The ECQ-E1335KZ is a polypropylene film capacitor which consists of two flexible electrodes, covered in plasticized polypropylene. This capacitor also features a metalized aluminum-polyphenylene-sulfide film for winding and insulation. These elements together form a sandwich-like structure that stores electric charge. When current flows from one electrode to the other, the electric charge is stored in the capacitor and then gradually released again.

The unique physical construction of the ECQ-E1335KZ ensures that it will have a low ESR, making it ideal for applications in which a low ESR is necessary. Its high surge and voltage-withstand capabilities also set it apart from many other capacitors in its field. By combining the two electrodes with an insulating plasticized polypropylene, the ECQ-E1335KZ offers an exceptional temperature stability over a broad range of temperatures.

In terms of its electrical properties, the ECQ-E1335KZ is noted for its impressive capacitance and dielectric strength. The combination of its polypropylene film and metalized aluminum-polyphenylene-sulfide structure gives the ECQ-E1335KZ a capacitance value of between 940-1080pF and a dielectric strength of 550V. This combination makes the capacitor an excellent choice for applications that require both high capacitance and voltage-withstand.

In addition to its electrical applications, the ECQ-E1335KZ has a variety of safety certifications such as UL, CSA, and TUV. This makes it well-suited to applications in safety-critical or hazardous environments, where reliable operation and loss prevention are paramount. The ECQ-E1335KZ is also one of the most durable film capacitors available, with an expected operating life of more than 20,000 hours

Overall, the ECQ-E1335KZ film capacitor is a highly reliable and versatile component. Thanks to its low ESR, high surge and voltage-withstand capabilities, and numerous safety certifications, the ECQ-E1335KZ is suitable for a variety of applications ranging from motor drives and energy storage to audio frequencies and HVAC. It is this versatility and reliability that has made the ECQ-E1335KZ one of the most popular film capacitors available on the market today.
