Film capacitors are widely used in electric and electronic equipment, automation control, instrumentation and so on. ECQ-E2105JB is one type of film capacitor, coming at a relatively low price. It is mainly used as transient voltage suppression capacitors etc. in automotive industry applications.

The external appearance of the ECQ-E2105JB is semi-transparent or transparent. It has yellow and white gold rings at both ends. It has a maximum of 15 mm in diameter, the outer shell is resistant to moisture, and the shape is mainly a cylindrical or cylindrical shape. It is soldered for mounting and has a low inductance design.

The ECQ-E2105JB exhibits good performance and reliable operation in circuit designs. It has a wide operating temperature range from -40℃ to +105℃ and a peak voltage range of 400v.It is also very cost-effective when compared to other film capacitors.

The ECQ-E2105JB consists of two layers of polyester films, typically 250V. It begins to work when the voltage applied to it exceeds the rated voltage, and has a self-recovery effect on the voltage. It allows a certain current to pass through and then restricts/cuts off the current. Its working mechanism is similar to a two-in-one mechanical switch. When the current passes through, a thin film layer bypasses the film layer and connects to the output load, thereby allowing the current to pass through. When hitting a pressure drop, the thin film layer separates from the film layer, disrupting the current flowing into the load. The ECQ-E2105JB will return to the original state after the voltage is removed.

The ECQ-E2105JB is mainly used to reduce excessive voltages or to protect power supply and other devices from high voltages, usually in the same environment as transistors, resistors and IC devices for protection purposes. It has wide application in electric vehicles, car audio devices, and other electric and electronic components are also very popular in automotive industry.

Due to its high performance, the ECQ-E2105JB is able to handle transient voltage surges and dips, making it ideal for protecting power supply and other sensitive electrical components from severe voltage impacts in automobiles. This capacitor is designed to protect against arcing and short-circuiting due to excessive current leakage.

The ECQ-E2105JB also has an extremely low ESR (Equivalent Series Resistance) which makes it suitable for pulse power supply applications, making it an ideal choice for large-scale telecommunications systems. Furthermore, due to its low inductance, it is suitable for high-speed and high-frequency switching applications such as switching power supplies, providing better protection against unexpected voltage transients.

In conclusion, the ECQ-E2105JB is a cost-effective and reliable film capacitor, suitable for a variety of applications. It offers excellent protection against high voltage surges and can handle transient voltages with ease. It also has low inductance and low ESR, meaning it is suitable for high-speed switching applications, as well as large scale telecommunications systems. This makes it a popular choice for applications in the automotive industry and for general electric and electronic components.
