604D391F200JT7

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarised, capacitors that have a larger capacitance than many other types with the same size. They are constructed with two aluminum foil with an oxide layer acting as the dielectric. The anode foil has impurities added to it, and the oxide layer acts as a passivation layer against oxidation as well, making them ideal for harsh environments. The anode foil is then rolled up with paper separators soaked in electrolytic solution. A second aluminum foil serves as the cathode. The electrolytic capacitor 604D391F200JT7 is a capacitor type made for general purpose applications. It is a Axial type, with a voltage rating of 400V, a capacitance of 200μF, a Dissipating Factor of 15%, and a Maximum Temperature Rating of -40 to +105°C. It typically provides a maximum ripple current of 270mA to 450mA.

Application Field and Working Principle

The 604D391F200JT7 capacitor is commonly used in automotive, audio-video, lighting, and home appliance applications, as it is qualified to AEC-Q200 standard. It can also be used as a smoothing capacitor in other applications. The working principle of the 604D391F200JT7 capacitor is the same as other aluminum electrolytic capacitors. Due to its polarised nature, it requires a voltage applied to the anode and cathode in the correct order in order for current to flow. Once the voltage is applied, the anode and cathode foils form a capacitor and current begins to flow. This current is regulated and limited by the Electrolytic Solution in the separator paper, forming a dielectric barrier between the two foils. The 604D391F200JT7 capacitor is designed for use in environments that require capacitors with long life, high ripple current capability, and high temperature ratings. The 604D391F200JT7 is rated for a long life of up to 4000 hours with a ripple current rating of 450mA. Additionally, its high temperature rating of -40 to +105°C makes it suitable for applications in extreme temperatures. Due to its unique design and construction, the 604D391F200JT7 aluminum electrolytic capacitor provides excellent performance in harsh environment applications.
