DME2S18K

Film capacitors

Ceramic capacitors with film equivalents offer many advantages over traditional ceramic ones, especially when dealing with high frequency circuitry. Metalized film capacitors (MFPs) are directly interchangeable with ceramic capacitors but offer better performance, greater stability, and smaller size. DME2S18K is a solutions provider of metalized film capacitors specifically designed for power applications.

Application Field

The DME2S18K offers a wide range of benefits, making it the ideal choice for power applications. Other products may utilize lower cost, separate x7r dielectric components, but the DME2S18K offers superior performance in high voltage applications. Additionally, DME2S18K capacitors are fully rated for rated voltage, capacitance, ESR, and ripple current. The DME2S18K utilizes high temperature metallized polyester film, making it suitable for temperatures up to 125 °C, making it ideal for reflow soldering. Its low ESR, low inductance, and high ripple current capabilities enable designers to use it in a wide variety of applications, including high speed switching power supplies, noise suppression, and wireless communication systems.

Working Principle

DME2S18K works by forming an electrical connection between two conductors inside a sealed package. When the two conductors are connected, an electric field is created that causes an electrical charge to move from one conductor to the other. This charge produces an energy storage effect in the form of a magnetic field, which is what is typically referred to as the \'capacitance\' of the component. The greater the capacitance, the greater the ability of the capacitor to store energy.

The DME2S18K utilizes a larger dielectric constant than ceramic capacitors, making the capacitance and ESR more stable and reliable over a wider range of environmental conditions. Additionally, the film capacitors have a much lower impedance than ceramic capacitors, allowing for higher voltage and ripple current ratings. The DME2S18K is well-suited for switching power supplies, high-frequency noise filtering, and electromagnetic interference (EMI) suppression.

Conclusion

The DME2S18K provides a reliable and cost-effective option for power applications, offering superior performance over traditional ceramic capacitors. The film capacitors\' low ESR, low inductance, and high ripple current capabilities make them ideal for high speed switching power supplies, noise suppression, and wireless communication systems. DME2S18K is a reliable solutions provider for metalized film capacitors, and is quickly becoming the industry standard component for power applications.
