How Polymer Aluminum Capacitor can be used to maximize its effect
Polymer aluminium capacitors are laminated aluminium electrolytic capacitors with high conductivity polymer materials as cathodes. They have superior electrical performance beyond existing liquid chip aluminium electrolytic capacitors and solid chip tantalum electrolytic capacitors. Polymer aluminium capacitors are within the rated voltage range and do not need to be used for voltage reduction.
When designing power transfer solutions for USB power supply and electronic systems and subsystems, including IC, specific application IC (ASIC), central processor (CPU), and field programmable gate array (field programmable gate array) (field programmable gate array), designers will continuously look for ways to improve efficiency while ensuring stable, noise-free power over a wide temperature range in a compact size.
They need to improve efficiency, stability and reliability, reduce costs, and reduce the size of the solution. At the same time, the increasing power performance requirements in applications must be met, including smoothing the input and output currents of power circuits, supporting peak power requirements, and suppressing voltage fluctuations.
To meet these challenges, designers need capacitors with low equivalent series resistance (ESR) and high frequency and low impedance to support ripple absorption and ensure smooth, fast transient response. Operational and supply chain reliability are also important.
Throughout these issues and options, polymer aluminium electrolytic capacitors are a good solution with high electrical performance and stability, low noise, good reliability, compact size, and low supply chain risk due to the non-use of conflicting materials. They have low ESR (usually measured in milliohms (m_) and high frequency (up to 500 kHz) low impedance, and provide excellent noise suppression, ripple absorption, and power line decoupling performance. In addition, it has capacitive stability at high operating frequency and temperature.
The performance characteristics of polymer aluminium electrolytic capacitors make them ideal for power management applications, including power supplies for CPUs, ASIC, GA, and other large ICs, and support peak power requirements for USB power systems.
