Aluminum - Polymer Capacitors : 4SVPS33M Application Field and Working Principle

Introduction

Aluminum-Polymer Capacitors have become widely used in electronics as demand for lighter, smaller, and more compact electrical components continues to grow. Aluminum-polymer capacitors offer superior performance compared to standard aluminum electrolytic capacitors, providing even lower ESL (Equivalent Series Inductance) and ESR (Equivalent Series Resistance) specs, as well as better temperature stability. The 4SVPS33M line of high-voltage capacitors is a popular choice for applications in the home entertainment, residential, communications and industrial fields.

Applications

The 4SVPS33M series of aluminum-polymer capacitors are primarily used in applications demanding high voltage electrical circuit components. The 4SVPS33M capacitors are rated at a voltage of up to 3.3Vdc. This can be advantageous in applications where circuits must accommodate large voltage spikes or surges, making the 4SVPS33M a suitable choice in the home entertainment and residential fields. This series of capacitors is also widely used in communications and industrial applications requiring high reliability and long life.

Types of Aluminum-Polymer Capacitors

Aluminum-polymer capacitors come in two basic types: effective capacitance type (EC) and total capacitance type (TC). The 4SVPS33M capacitors are of the EC type, which means that the capacitance is spread uniformly over the entire capacitor element. The EC type offers superior mechanical stability, better performance and reliability, and a longer usable lifespan compared to the TC type. This makes 4SVPS33M capacitors a preferred choice in high-voltage applications.

Working Principle of 4SVPS33M Capacitors

The 4SVPS33M capacitors use an improved solid aluminum-polymer construction. The innovative design consists of two parallel aluminum electrodes that are separated by the aluminum-polymer body. The dielectric within the capacitor consists of a continuous film of aluminum-polymer that wraps around both electrodes and forms the capacitance. The benefit of this design is that it allows for superior heat dissipation and ensures improved mechanical ruggedness, as well as low ESR and ESL values.

The 4SVPS33M aluminum-polymer capacitors are capable of operating without failure for long periods of time at a rated voltage of up to 3.3V. This makes them ideal for applications in which a component must be capable of withstanding high operating temperatures and frequent voltage switching, such as in communications, industrial, and home entertainment sectors.

Conclusion

The 4SVPS33M series of aluminum-polymer capacitors offer superior performance and reliability in applications demanding high voltages. The innovative design of the 4SVPS33M capacitors allows for improved heat dissipation and mechanical ruggedness, as well as low ESR and ESL values. This series of capacitors is suitable for applications in the home entertainment, communications, residential, and industrial fields, where it will provide reliable operation for long periods of time without failure.
