Aluminum - Polymer Capacitors

Aluminum - polymer capacitors (also known as Aluminum Electrolytic Capacitors) are real time-savers in industry and performance optimizers in commercial environments. Despite their small size and light weight, these capacitors have a remarkable combination of important characteristics; they offer excellent reliability, superior electrical performance, and superior environmental protection. The product range covers Miniature, Large Can, Radial, Polymer, SMD and other special versions, enabling adaptation to a wide range of industrial applications.

APXE160ARA121MH70G

APXE160ARA121MH70G is a radial, high temperature, aluminum - polymer capacitor. It has a 0.15A voltage rating, a -40 to +125 degree Celsius operating temperature, and a 3 mm lead length.

Application Field

APXE160ARA121MH70G capacitors are resistant to gas, oil, and thermal shock, making them suitable for use in energy systems and outdoor applications. In addition, due to their higher quality, such as a low leakage current, a high capacitance, a high ESR (equivalent series resistance) and an extreme temperature capability, these capacitors offer highly reliable service in lightning and switching power supplies, solar power applications, and can withstand extreme temperatures.

Working Principle

Aluminum - polymer capacitors consist of two electrodes and an electrolyte composed of special polymer. The basic operation works like this: the anode is made of aluminum foil, while the cathode is made of polymerized carbon. The anode and cathode are placed between two dielectric layers and surrounded by electrolyte. When a voltage is applied across the electrodes, an electric field develops in the dielectric material, allowing current to flow through it. This, in turn, creates a capacitive charge.

When the polarity of the applied voltage reverses, the electrolyte is repolarized and returns to its original non-charged state. The cycle continues as the external voltage is continually applied and oscillates in its polarity. This cycle of charge and discharge is the principle on which the capacitor operates.

Aluminum - polymer capacitors are used in numerous commercial applications and are steadily replacing other types of capacitors due to their superior performance and reliability. They offer superior electrical characteristics, extreme temperature capability and superior environmental protection, making them ideal for use in many industrial applications.
