Aluminum - Polymer Capacitors have a huge range of application fields and have gained considerable momentum in recent years. Prominent among the application fields of Aluminum - Polymer Capacitors are power electronics, smart cards, MEMS and high-power (>100W) lighting. Moreover, these capacitors are promising for automotive, medical and telecommunications markets with their high temperature operating capabilities.
The working principle of an Aluminum - Polymer Capacitor consists of two electrodes with a dielectric between them. When a voltage is applied across the two electrodes, electric charge is stored on one or both of the electrodes, depending upon the reverse polarization direction of the electrodes and the applied voltage. This electric charge stored on one or both of the electrodes creates an electrostatic charge field between the two electrodes, thus forming a capacitor. Aluminum - Polymer Capacitors are unique in that the dielectric is basically an ionically conductive polymer containing some additives to provide appropriate favorable characteristics.
The working principles of specific Aluminum - Polymer Capacitors in particular application fields may differ from one application to another. Generally, these capacitors are easier to handle and have greater capacitance and energy density in comparison to other capacitors. Also, they are very efficient in size and weight as well as able to hold a significant amount of charge per unit volume.
In power electronics applications, Aluminum - Polymer Capacitors offer significant advantages, primarily due to their low Equivalent Series Resistance (ESR) and high ripple current ratings. Low ESR results in better voltage stability, higher switching frequencies and improved efficiency. High ripple current ratings reduce audible noise and extend the lifetime of the installation.
In smart cards, Aluminum - Polymer Capacitors provide benefits such as high capacitance, high long-term stability, low leakage resistance and low temperature coefficient. It is also possible to combine Aluminum - Polymer Capacitors with other components, such as resistors and transistors, to create a multi-functional device. This integration provides greater space savings, lower profile and improved robustness.
MEMS (Micro Electrical Mechanical Systems) applications utilize Aluminum - Polymer Capacitors for a variety of purposes, such as capacitor-sensor fabrication, advanced sensing and actuation, frequency range selection and filtering, and analog-to-digital conversions. They are also used for improving the performance of MEMS oscillators and resonators. Furthermore, Aluminum - Polymer Capacitors can be used in high-power (>100W) lighting systems to reduce the effect of illumination on the continuity of power supply and provide improved dimming capability.
Aluminum - Polymer Capacitors are increasingly finding usage in automotive applications due to their small size, high capacitance and low leakage. These capacitors can be used in combination with other components to improve the efficiency and performance of vehicle systems such as power steering, automatic brake systems and electric power steering. In addition, they can be provided with integrated temperature sensors, providing improved monitoring of temperature in the vehicle.
Medical applications of Aluminum - Polymer Capacitors include implantable devices, such as pacemakers, insulin pumps and implantable cardiac defibrillators. These capacitors offer high ESR values and robust radiopaque designs that provide excellent performance in applications where RF energy induction is needed. Also, their small size, excellent power ratings, improved circuit performance and reliability are ideal for medical applications.
Telecommunication applications for Aluminum - Polymer Capacitors include providing higher insulation to support high frequency communications, providing robust EMI protection, and acting as miniaturized power supply for various types of communication cells. These capacitors are also highly ideal for controlling interference between two different types of communication signals, and for providing impedance compensation in high frequency Analog-to-Digital (ADC) converter circuits.
Aluminum - Polymer Capacitors have a wide range of application fields and working principles. The technology has seen significant advances in recent times and continues to grow in popularity. They offer advantages such as their small size, high capacitance, low leakage resistance, high temperature ratings and improved efficiency.
