Aluminum-polymer capacitors, such as the ESR391M02XB, are relatively new capacitors that offer particular benefits over traditional electrolytic capacitors. They are capable of sustained performance over a wide range of temperatures, operate with minimal impedance, and possess excellent load life characteristics. Their reduced physical size makes them effective alternatives in many markets, where a significant number of components need to be packed into the same space.

The ESR391M02XB aluminum-polymer capacitor utilizes a three-dimensional sandwich of organic polymers and aluminum foils to create both a positive anion and a negative-ion bearing capacitor. The polymers cover both electrodes and serve as distance spacers for the many layers of aluminum or copper foils of the capacitor. This form of construction provides an exceptionally large surface area for the capacitor, allowing for greater capacitance and lower equivalent series resistance (ESR).

The ESR391M02XB is designed for use in miniature capacitors applications such as portable computers, digital media players, and even implantable medical devices. Its small size and impressive bleeding capabilities combine to make it the perfect choice for space-intensive devices. With low ESR and a low temperature coefficient, the ESR391M02XB is able to maintain performance during temperature fluctuations, making it highly resilient and adaptable to a variety of environments.

The ERS391M02XB’s impressive capacitance ratings of up to 1.2 F make it suitable for many uses. It also offers an increased load life by utilizing an aluminum-polymer based dielectric, helping to prevent voltage breakdown or capacitor heater issues. The capacitor also has a wide and stable operating temperature range, making it functional in almost any temperature environment, from -40 to 85 degrees Celsius.

With its low impedance, small size and high capacitance rating, the ESR391M02XB aluminum-polymer capacitor is perfect for a wide variety of applications. Its low ESR and excellent load life characteristics make it suitable for use in consumer electronics, computers and communication devices. Its impressive stable temperature ranges make it a highly reliable capacitor for extreme temperatures, and its impressive load life ensures that it is capable of performing to the required specifications in any environment.
