Film capacitors, also known as plastic film capacitors, are electronic components used to store electrical energy and to separate signal bands according to their capacitance values. They are used in power supplies and in a variety of electrical and electronic circuits. The ECQ-E1185KF is a type of film capacitor which has recently become popular as a component for switch mode power supplies (SMPS). This article will explain the application field and working principle of the ECQ-E1185KF.

The ECQ-E1185KF is a Polyethylene Naphthalate (PEN) film capacitor designed specifically for use in high frequency switch mode power supplies. The PEN film offers excellent temperature stability, good reliability and is a low-inductance capacitor. The ECQ-E1185KF can be used in AC and DC SMPS, as well as in motor control, power conditioning and other power supply applications. The ECQ-E1185KF has a tangent of loss angle of 1.1%, a capacitance of 270 μF and a working voltage of 190V.

The ECQ-E1185KF works by storing energy in the electric field between its electrodes. When the voltage across the capacitor exceeds the capacitor’s breakdown voltage, the dielectric breaks down and the capacitor discharges. The ECQ-E1185KF also has a small ESR (equivalent series resistance) which helps reduce losses in the circuit due to the internal resistance of the capacitor. The low ESR helps to make the capacitor more efficient since it helps reduce the amount of electrical energy that is converted to heat.

The ECQ-E1185KF is ideal for use in SMPS and high-power motor control applications. Its low-inductance construction helps to reduce electromagnetic interference (EMI) in power supplies, while its high temperature stability helps ensure a long life and reliable performance. Additionally, its low ESR helps reduce system losses and improve efficiency. The capacitor can also be used in AC and DC circuits, as well as motor control circuits, low-voltage power supplies, UPS systems and more.

In summary, the ECQ-E1185KF is a Polyethylene Naphthalate film capacitor designed for use in high-frequency switch mode power supplies, motor control circuits and other high-power applications. The capacitor offers excellent temperature stability, low ESR for improved efficiency, and a low-inductance design for reduced EMI. It is capable of performing well in a wide range of applications, from AC and DC circuits to motor control and power conditioning. In conclusion, the ECQ-E1185KF is an excellent choice for a wide range of applications in the power supply and motor control fields.
