Aluminum electrolytic capacitors are widely used for energy storage, signal filtering and electric noise reduction, making them one of the most commonly-found components in electronic systems. The SEK470M400ST is a type of aluminum electrolytic capacitor specially designed for applications that involve extreme temperature and/or altitude conditions, such as automotive and aerospace systems.

The SEK470M400ST has a particularly special constructions. Its housing is made out of a silver-colored aluminum casing and its casing is stamped with an MT branded logo in 2 main areas, sides and bottom. Inside, it contains two metallic aluminum strip plates and a special dielectric medium sealed between two electrodes. This special construction allows for a working temperature range of -55°C to 105°C and an altitude range of up to 9000 meters.

The capacitor’s working principle is quite simple. Its construction enables a polarized electric field to be created when a voltage is applied to its two plates. This field stores energy and acts as an insulator, which enables the capacitor to filter out and reject alternating electric signals. By controlling electric flow and field strength, the SEK470M400ST is able to filter out electric signals and reduce noise.

As its voltage and current rating indicate, the SEK470M400ST is an ideal choice for use in high-temperature and/or altitude applications. Its temperature range, high voltage rating, and noise reduction capabilities make it suitable for use in automotive and aerospace systems that require extreme temperature/altitude operation. Its construction also makes it very durable and reliable, which is further enhanced by its low leakage current ratings.

The SEK470M400ST also features a variety of benefits over other capacitor technologies. It is more cost-effective than other capacitors, easier to solder and mount, and can be used in a wider variety of applications due to its wide temperature/altitude range. It also has a long service life compared to other capacitors, and can withstand the rigors of extreme temperature and altitude conditions.

In conclusion, the SEK470M400ST is an aluminum electrolytic capacitor with a special constructions designed for applications that involve extreme temperature and/or altitude conditions. Its working principle is based on the creation of a polarized electric field between two plates, which enables it to filter out and reduce electric noise. Furthermore, its low voltage and current ratings, cost-effectiveness, and long service life make it the perfect choice for automotive and aerospace applications.
