Aluminum electrolytic capacitors are widely used because of their relatively large capacitance and relatively low cost in the market. TE1400-E3 is an aluminum electrolytic capacitor developed by TE Connectivity, which is often used in automotive, lighting and industrial applications. In this article, the application field and the working principle of the TE1400-E3 aluminum electrolytic capacitor will be discussed.

The TE1400-E3 aluminum electrolytic capacitor consists of a conductor (aluminum foil) and dielectric (aluminum oxide). The construction of this type of capacitor is a conductor with an oxide layer. The conductor has an anode and a cathode, which are normally separated by a dielectric material or material in isolation. The aluminum foil serves as the anode and the cathode is made up of the oxide layer that is on the aluminum foil. The oxide layer is formed through the electrochemical reaction of the aluminum foil and the electrolyte. The dielectric material of an electrolytic capacitor is mainly a porous oxide layer. The oxide layer has a high dielectric breakdown strength and also a lower dielectric constant than other dielectrics, allowing electrolytic capacitors to achieve large capacitance.

TE1400-E3 aluminum electrolytic capacitors have low-profile designs and are particularly suitable for use in tight spaces and densely populated PCBs. The volumetric efficiency of aluminum electrolytic capacitors increases as the supply of aluminum electrolytic capacitors in the market increases. The TE1400-E3 aluminum electrolytic capacitor maintains excellent volumetric efficiency while still having a larger capacitance. The TE1400-E3 has an impedance ranging from 5m Ω to 120m Ω, depending on the temperature and capacitance. The working voltage ranges from 2.5 V to 6.3 V.

The main application field of TE1400-E3 aluminum electrolytic capacitor is in automotive, lighting, and industrial products. In automotive products, TE1400-E3 can help reduce the vibration generated by the vehicle, as well as extend the life of the vehicle’s battery. In lighting applications, TE1400-E3 is used to reduce the power consumption, improve lighting performance, and reduce light pollution. In industrial products, TE1400-E3 is used in power supplies, regulators, power filters, etc. to reduce the interference generated by the equipment.

The underlying working principle of TE1400-E3 aluminum electrolytic capacitor is electrochemical energy storage. The aluminum electrolytic capacitor is constructed of an anode (aluminum foil) and a cathode (oxide layer formed on the aluminum foil). When an electric current passes through the aluminum electrolytic capacitor, a storage charge is built up, which is proportional to the amount of current. The charging and discharging time of the capacitor is very short, which is beneficial for providing the initial energy in high-peak current applications. Compared to other types of capacitor, aluminum electrolytic capacitors are the cheapest and have a higher capacity. In addition, they generally have higher ESR, which improves power supply stability.

In conclusion, TE1400-E3 aluminum electrolytic capacitor is a low-profile product which can be used in automotive, lighting, and industrial applications. The underlying working principle of the capacitor is electrochemical energy storage which charges and discharges very quickly. The advantages of this capacitor include low cost, high capacitance, and high ESR which improves power stability.
