Working Principle

The ECH-U1H103GB5 is a type of film capacitor. Film capacitors are constructed with an insulating plastic film between an electrode layer of metal and an electrolyte. As the applied voltage increases, the dielectric strength of the plastic film weakens at the point of contact, allowing electrons to flow. This creates an electric field with a strong capacitance, which creates the necessary energy storage for the device.

The capacity of the ECH-U1H103GB5 is determined by the dielectric constant, the electrode area, and the thickness of the plastic film. The beneficial characteristics of the film are its low loss factor, high insulation resistance, and extremely stable capacitance over a wide temperature range. This makes it ideal for use in high voltage and high frequency applications.

Conclusion

The ECH-U1H103GB5 is an excellent choice for a wide range of industrial, mobile, and medical applications. Its superior performance and strong capacitance make it ideal for high voltage, high frequency applications, as well as low loss and EMI/RFI filtration. With its low ESL, it ensures reliable and efficient performance and is suitable for a variety of electrical components.
