Aluminum electrolytic capacitors are electronic components that are used in many electronic circuits for basic functions such as storing energy, filtering signal frequencies, and providing energy for switching transients. The EEV-FK1H331Q is a miniature aluminum electrolytic capacitor that offers a high capacitance in a very small package. It is ideal for use in portable digital devices such as cell phones, personal digital assistants, and portable media players.

Capacitor Construction

The EEV-FK1H331Q is constructed with a conventional aluminum electrolytic capacitor design. It has two plates made of aluminum foil, with a separator between them. One of the plates has an oxide coating that acts as the dielectric layer of the capacitor. A conductive electrolyte is then added between the plates to complete the structure. The electrolyte is essential to the operation of the capacitor, as it is responsible for the majority of the capacitance. The other plate on the capacitor is either an aluminum foil or a conductive nickel-plated steel plate.

Technical Specifications

The EEV-FK1H331Q aluminum electrolytic capacitor has a capacitance of 1000 μF, a voltage rating of 25 volts, and an operating temperature range of -40°C to +85°C. It also has a polarity indicating the positive and negative terminals. It is available in a 6.3x10mm package, and the lead spacing is 4.5mm. The EEV-FK1H331Q capacitor has a failure rate of 0.5% per 1000 hours at a temperature of 85°C.

Application Field and Working Principle

The EEV-FK1H331Q aluminum electrolytic capacitor is primarily used for filtering and storing energy in electronic circuits. The voltage rating and capacitance of the device allow it to be used in a wide range of applications, from AC power lines to low frequency signals. It can also be used in high frequency applications, such as RF switching circuits. The working principle of the capacitor is based on the dielectric and conductive properties of its components. When a voltage is applied to the capacitor, the oxide coating on one of the aluminum plates creates a field that pulls electrons from the electrolyte onto the plate. This causes a build up of charge, which then acts as a store of energy. As the voltage is changed, the charge on the capacitor is also changed, allowing it to filter signals or store and release energy.

Conclusion

The EEV-FK1H331Q aluminum electrolytic capacitor is a miniature capacitor that offers a high capacitance in a small package. It is ideal for use in portable devices, and can also be used for filtering and storing energy in a range of circuits. It has a capacitance of 1000μF, a voltage rating of 25V, and an operating temperature range of -40°C to +85°C. The working principle of the capacitor is based on the dielectric and conductive properties of its components, allowing it to store and release energy as the voltage is changed.
