Film Capacitors

Film capacitors, also known as plastic film capacitors, are electrical components made by wrapping a thin plastic film around a metal core. This combination creates a flat surface that is electrically insulated from the core, forming two metal plates. These plates, or "plates," are charged with a voltage and separated by the film, forming a dielectric material that can store electrical energy. The primary use of film capacitors is in power supplies, where they are used to increase the power efficiency of the device, reduce ripple, and reduce EMI emissions.

ECW-H12163RJV Application Field and Working Principle

Film capacitors of the ECW-H12163RJV series are ideal for power supplies and DC/DC converters where low ESR, high ripple current capabilities and noise suppression are needed. The primary application of this series is in server and storage products. ECW-H12163RJV film capacitors are smaller in size and have high capacitance values, making them a preferred choice in a variety of power supply applications. They have a maximum operating temperature of 125°C, a rated voltage of 63V, and an insulation resistance of 500MΩ.

The ECW-H12163RJV series capacitors are polarized electrochemical, meaning they have an anode and a cathode connected by an electrolyte. Polarized capacitors are usually used in DC applications where the anode and cathode never switch polarity. The capacitance of the ECW-H12163RJV series capacitors is determined by the thickness and dielectric constant of the plastic film. When a voltage is applied to the capacitor, the dielectric material stores an electrical field, and electrons move from one plate to the other. The greater the capacitance of the capacitor, the more electrical energy it can store.

The ECW-H12163RJV series capacitors have low-ESR characteristics, meaning that they can handle relatively high levels of ripple current and mitigate noise suppression in electrical circuitry. This is advantageous for applications such as DC/DC conversions. In addition, the capacitors have a high insulation resistance rating of 500MΩ, which protects the capacitor from shorting out and causing damage to the circuit.

ECW-H12163RJV film capacitors are designed for use in demanding power supply and DC/DC converter applications. They have high peak current capabilities, a high insulation resistance rating, and low ESR characteristics that make them well-suited for reliable and efficient DC power supplies. Additionally, they are lightweight, compact, and feature a low profile that enables them to fit into tight spaces easily.
