Film Capacitors

A film capacitor is a type of capacitor with dielectric refrigerant film that serves as an insulation between the two conducting surfaces. Film capacitors are generally more lightweight and smaller in size than aluminum electrolytic capacitors and thus can offer higher levels of precision and accuracy due to the stable characteristics over a range of temperatures and frequencies. The ECH-U1H181GB5 is one such type, and is suitable for use in many commercial and industrial applications.

ECH-U1H181GB5 Overview

The ECH-U1H181GB5 is a radial film capacitor manufactured with a high temperature specialty grade dielectric, metallized polypropylene film. This capacitor is designed with a hermetically sealed electrolytic quality tin plated aluminum case. This combination of features makes it suitable for use in harsh ambient environments. Additionally, it also has superior capacitance stability and remarkable frequency characteristics making it an ideal choice for many applications.

Applications

Due to its unique characteristics, the ECH-U1H181GB5 is suitable for a wide range of commercial and industrial applications including:

• High-frequency amplifiers
• Power filters
• DC-DC converters
• Saw filters
• Power supply for telecom
• AC-DC converters
• Deflection systems

Working Principle

The ECH-U1H181GB5 operates on the principle of dielectric refrigerant film which offers an insulation between the two conducting surfaces. When a voltage is applied across the conducting surfaces, a voltage drop occurs across the capacitor due to the polarizing reaction of the dielectric material. This reaction creates an electric field within the film which stores electrical energy in the form of electrostatic charge. The amount of charge stored is proportional to the amount of voltage applied across the two conducting surfaces. When the applied voltage is removed, the stored charge dissipates and the capacitor returns to its neutral state.

Design Considerations

The ECH-U1H181GB5 is designed to have extremely stable characteristics over a wide range of temperatures and frequencies. However, care should still be taken when designing or using the capacitor as there are several design considerations which should be taken into account. These include:

• Capacitance tolerance
• Ripple current
• Voltage rating
• Surge voltage capability
• Leakage current
• Dielectric absorption
• Self-inductance

When designing with a capacitor, it is important to familiarise yourself with the datasheet for the capacitor and take all of the necessary precautions to ensure robust and reliable operation.

Conclusion

The ECH-U1H181GB5 is a type of radial film capacitor which is suitable for a wide range of applications including power supplies for telecoms, high-frequency amplifiers, power filters, and DC-DC converters. It has excellent temperature, frequency, and capacitance stability, making it an ideal choice for many applications. Designers should be aware of the various design considerations as outlined in the datasheet to ensure the robust and reliable operation of the capacitor.
