  • Understanding CBB65 Motor Run Capacitors: Applications, Features and Selection Tips
    Feb 03, 2026
    In modern HVAC and motor-driven systems, stable motor operation is essential for efficiency, safety, and long-term reliability. Among various AC motor capacitors, the CBB65 motor run capacitor has become one of the most widely used solutions for air conditioners, water pumps, and ventilation systems. In this blog, we will take a closer look at what CBB65 capacitors are, why they are so popular, and how to choose the right one for your application. What Is a CBB65 Motor Run Capacitor? A CBB65 capacitor is an AC motor run capacitor made with metallized polypropylene film (MPP). Its main function is to provide phase shifting for single-phase motors, allowing them to run smoothly and efficiently during continuous operation. Unlike electrolytic capacitors, CBB65 capacitors are designed for...

  • What Is an X2 Capacitor and Why Is It Used in EMI Suppression Applications?
    Jan 27, 2026
    Introduction In modern electronic equipment, electromagnetic interference (EMI) is a common issue that can affect performance and safety. To reduce EMI and improve system reliability, X2 capacitors are widely used in power input and noise suppression circuits. In this article, we explain what an X2 capacitor is, how it works, and why X2 capacitors are essential in EMI suppression applications. What Is an X2 Capacitor? An X2 capacitor is a type of safety film capacitor designed to be connected across the AC power line (Line to Line). It is mainly used to suppress electrical noise and voltage spikes generated by switching devices and external interference. X2 capacitors are typically manufactured using metallized polypropylene (MPP) film, offering stable electrical performance and reliab...

  • How Dielectric Film Selection Impacts Film Capacitor Performance and Reliability
    Jan 09, 2026
    In film capacitor manufacturing, electrical performance and long-term reliability are fundamentally determined by the quality of the dielectric film. While external dimensions and rated values are easy to specify, the real performance of a capacitor depends on how well the dielectric material performs under electrical stress, thermal cycling, and continuous operation. For applications such as motor run capacitors, power supplies, and industrial electronics, proper dielectric film selection is not simply a material choice—it is a critical engineering decision that directly affects stability, efficiency, and service life.     The Role of Dielectric Film in Film Capacitors The dielectric film acts as the insulating medium between capacitor electrodes and defines the capacitor...
