Aluminum-Polymer Capacitors (EEF-UD0E181XE)Aluminum-polymer capacitors, also known as “hybrid” capacitors, are a relatively new type of capacitor that offers a combination of the benefits of both aluminum electrolytic capacitors and ceramic capacitors. The capacitors are composed of a polymer material, usually polyethylene, with aluminum plates sandwiched between two layers of the material. This combination provides good capacitance retention, excellent frequency response, and the ability to withstand harsh conditions.EEF-UD0E181XE is one of the most popular aluminum-polymer capacitors currently available on the market. It is an aluminum electrolytic capacitor with a construction featuring an anode (positive electrode) composed of polyethylene-terephthalate/copper-clad aluminum plates and a dielectric composed of polyethylene-terephthalate. The anode and dielectric are then encapsulated in a polyethylene-terephthalate/polyamide (PA 66) sleeve. This capacitor has an environmental temperature range of -40 to +125 C (-40 to +257 F) and a nominal capacitance of 180uF (microfarads) at 20V DC (direct current).There are several advantages to using aluminum-polymer capacitors instead of traditional aluminum electrolytic capacitors. The main advantages are improved frequency response, increased ripple current capacity, better temperature stability, and increased capacitor life. Additionally, in comparison to foam electrolytic capacitors, aluminum-polymer capacitors are not prone to leakage and offer improved quality of sound in audio applications.The frequency response of aluminum-polymer capacitors depends on several factors such as electrolyte type, capacitance value, environment temperature, and working voltage. These capacitors have an operating temperature range of -40 to +125 C (-40 to +257 F), making them suitable for a range of applications such as switching power supplies, DC-DC converters, high-end transducers, and power amplifiers.The working principle of aluminum-polymer capacitor lies in the fact that they store energy between two parallel plates by creating an electrostatic field. As current is applied, positive and negative ions of the electrolyte are attracted to the plates, creating an electrostatic field. Similar to traditional aluminum electrolytic capacitors, aluminum-polymer capacitors are polarized, which means that the positive and negative terminals have to be connected in the right direction.Aluminum-polymer capacitors offer many advantages for various applications, making them popular for use in audio, automotive, computer, and telecommunications applications. These capacitors are typically more expensive than traditional aluminum electrolytic capacitors due to their improved performance characteristics. However, their improved performance and increased lifespan usually more than offset their higher cost.
