SEK470M016ST

Aluminum electrolytic capacitors are capacitors consisting of an anode made of a pure aluminum foil, a dielectric and electrolyte-soaked paper, and a cathode foil, often referred to as polarized aluminum electrolytic capacitors. The SEK470M016ST is an aluminum electrolytic capacitor with a maximum onboard temperature of +105 ℃ and a maximum reflow temperature of +235 ℃. It is an ideal choice for applications requiring reliable, extensive life performance.

The SEK470M016ST is specifically designed for use in automotive systems, communication systems, consumer electronics, and other automated equipment requiring long life and low leakage. Its large capacitance and low ESR feature make it an ideal choice for large power supply systems and high frequency circuits which need to run at low voltage. With its exceptionally low ESR, this capacitor achieves high transient response and long-term performance in a variety of applications.

The core technology of the SEK470M016ST is a special electrolyte chemistry, which uses aluminum foil, dielectric wax paper, and a corrosion-resistant metal oxide layer. This combination of materials allows the capacitor to withstand temperatures up to +105 ℃ with minimal leakage. Additionally, the combination of these materials makes the SEK470M016ST an ideal choice for applications requiring reliable long life performance.

The working principle of this type of aluminum electrolytic capacitor is based on the Faraday law of electrolysis. This states that any electric current will cause an electrolyte to become polarized and form an electrolyte concentration cell. When the positive and negative electrodes of this cell are connected to an external electric circuit, an electrolytic capacitor is formed. The electric field across the dielectric wax paper causes the formation of a thin layer of oxide, which acts as an insulator. The oxide layer is well insulated against currents, and thus contributes to the extended life of the aluminum electrolytic capacitor.

In conclusion, the SEK470M016ST aluminum electrolytic capacitor is an ideal choice for applications requiring reliable, extended life performance. Thanks to its advanced electrolyte chemistry, the capacitor can withstand extreme temperatures while maintaining minimal leakage. Thanks to its low ESR and transient response, the capacitor offers excellent performance and long life in a variety of applications.
