Film capacitors, also known as plastic film capacitors, are a type of electrical capacitor commonly used in a wide range of applications that require small capacitances. They offer superior temperature performance, higher ripple current capabilities and considerably longer lifetime than ceramic or electrolytic capacitors. The DMM4P1K-F series film capacitors are highly stable, low-ESL components that feature long life ratings and excellent voltage endurance capabilities.

The DMM4P1K-F series film capacitors are designed for use in a wide variety of power system applications, such as power sources, frequency converters, inverters, rectifiers and oscillators. These components are ideal for applications requiring stable capacitance and low-ESL. The DMM4P1K-F is also suitable for applications where the operating temperature range is wide and the load current is high.

Working Principle: The DMM4P1K-F film capacitor uses polyester film as the dielectric material, which is highly stable and provides superior performance over other types of capacitors. A thin metal foil is used as the electrodes of the capacitor which is connected to a metallic connection that serves as the capacitor’s outer body. The connections of the capacitor are designed to keep the inner circuitry and dielectric material completely isolated from the external environment.

Electrical performance: Depending on the design and voltage rating, the DMM4P1K-F can offer low leakage current and high insulation resistance values. This makes the capacitor suitable for use in high voltage applications, such as power supplies and charge pumps or modulation circuits. The capacitor also provides excellent high frequency performance, making it suitable for use in switching supplies and power factor correction circuits.

Mechanical performance: The DMM4P1K-F capacitor is highly reliable, featuring an extended life-span and resistance to shock and vibration. The dielectric film provides excellent voltage resistance and temperature stability, making the component suitable for use in applications that require high performance even at elevated temperatures. The capacitor is also designed to be mechanically robust, ensuring sufficient mechanical strength while being space-saving.

The DMM4P1K-F series film capacitors are a type of electrical component that offers high performance and long life ratings. These capacitors are highly reliable and are ideal for applications requiring small capacitances and robustness. With its excellent electrical and mechanical performance, the DMM4P1K-F is perfect for use in power systems, frequency converters, inverters, rectifiers and oscillators.
