Aluminum - Polymer Capacitors

Aluminum - Polymer Capacitors, popularly known as polymer electrolytic capacitors, are non-polar electrolytic capacitors that feature a capacitance range from a few microfarads up to several hundred microfarads (10 uF to 200 uF). They are mainly used for filtering and decoupling in consumer electronic appliances. The EEF-CX0E471R is an aluminum-polymer capacitor model that boasts superior capacitance stability and wide capacitance range.

The Construction of EEF-CX0E471R

EEF-CX0E471R utilizes aluminum foil as the anode, a proprietary polymer as the electrolyte, and an aluminum-metalized cathode foil as the medium. While most aluminum electrolytic capacitors use large surface areas of aluminum foil to assure a long lifetime, the small size of the EEF-CX0E471R capacitor means that its aluminum foil has a much smaller surface area, which guarantees its low equivalent series resistance (ESR).

Applications

The EEF-CX0E471R is ideal for use in applications where space is a concern, such as in smart phones, tablets and laptops, as well as in MCU, audio amplifiers and power supply circuits. Depending on the specific application and requirements, the EEF-CX0e471R is available in both through-hole and surface-mount devices.

Working Principle

The EEF-CX0E471R capacitor works on the principle of capacitor action, in which two metal plates are separated by a dielectric material. When a voltage is applied to the plates, a charge builds up that can be stored in the capacitors. The capacitors are then able to hold the charge for a certain period of time, allowing them to filter out any undesirable signals.

Advantages of EEF-CX0E471R Aluminum-Polymer Capacitors

The EEF-CX0E471R Aluminum-Polymer Capacitor is ideal for use in applications where space is a concern, like miniaturized circuits, as it is designed to be much smaller than traditional aluminum electrolytic capacitors. Its proprietary polymer electrolyte also ensures excellent capacitance stability and wide capacitance range. Furthermore, the aluminum-metalized cathode foil design helps to reduce the equivalent series resistance (ESR), and low ESR allows for lower self-discharge, thus resulting in a longer operational life.

Conclusion

The EEF-CX0E471R Aluminum-Polymer Capacitor is an electrical component ideal for use in miniaturized circuits, as it can act as a reliable filter to remove undesirable signals. It is also small and lightweight, making it suitable for applications where space is a concern. The EEF-CX0E471R Capacitor also has excellent capacitance stability and wide capacitance range, as well as low ESR, allowing for longer operational life.
