Film capacitors are a group of capacitors that use thin plastic films as the main medium for storing electrical energy. The ECQ-P1H821JZ is one such capacitor, and it has a range of features that make it an attractive option for certain applications. Below, we will explore the application area and working principle of this device.

Application Field

The ECQ-P1H821JZ is specially designed for high-frequency pulse applications. It is primarily used in switching power supplies, dc-dc converters, motor drives, inverters, and any other applications where you need to frequent apply short-duration, high-frequency pulses. The device is also well-suited for EMI (Electromagnetic Interference) filtering.

In addition to high-frequency pulse applications, the ECQ-P1H821JZ can also be used in wave shaping and signal processing circuits, as well as for general-purpose DC blocking and AC coupling. It can be used at frequencies up to 1MHz, making it an ideal choice for a wide range of applications. It is also highly compact, so it can be easily integrated into any circuit.

Working Principle

The ECQ-P1H821JZ is a radial-lead, film-dielectric, non-polarized capacitor with capacitance values from 1pF to 0.001µF. It consists of a thin dielectric film and two electrode plates. When a voltage is applied across the electrode plates, a electric field is created in the film, which causes electric charges to be stored on the electrodes. Thus, capacitance is generated between the two electrodes.

In the ECQ-P1H821JZ, the capacitance is generated by an electrolytic process, meaning that the dielectric film is an electrolytic solution. During operation, liquid is electrically driven into the alternating layers of dielectric film and conductive electrode plates, resulting in the formation of double-layer, liquid-filled capacitors.

Due to their high capacitance and low effective series resistance (ESR), the ECQ-P1H821JZ is highly suitable for high-frequency pulse applications, such as those mentioned previously. It can also handle high transient voltages, so it is particularly well-suited for operation in high-voltage environments.

Additionally, the ECQ-P1H821JZ is highly reliable, with a long service life and high tolerance to temperature and humidity. The device is also extremely affordable, so it is a great choice for any budget-conscious application.

In summary, the ECQ-P1H821JZ is a film capacitor that is specifically designed for high-frequency pulse applications. It offers high capacitance and low ESR, as well as a long service life, high temperature tolerance, and excellent affordability. As a result, it is the perfect choice for any application where you need to frequent apply short-duration, high-frequency pulses.
