Aluminum electrolytic capacitors are a type of capacitor that uses an aluminum oxide layer as its dielectric medium. The E36D451HPN152TED0M is an aluminum electrolytic capacitor of the surface mount type, with moderate capacitance in the range of 45 to 155 uF and a rated voltage of 25 Vdc. It has a conductive polymer cathode material, low ESR, and high ripple current capability.

The E36D451HPN152TED0M is suitable for a number of electronic applications, such as high frequency switching power supply circuits, high frequency dc/dc converters, general dc bias circuits, and filter circuits. It is also suitable for hybrid automotive modules and systems, due to its excellent low ESR characteristics and stable performance in harsh automotive environments.

As with all aluminum electrolytic capacitors, the E36D451HPN152TED0M utilizes a combination of forces to create and maintain its electric field. The dielectric, an insulator, is an oxide layer formed on the aluminum electrode by chemical oxidation. This layer is held in place on the outer part by solvent binding, while the inner part is held in place by the combination of mechanical force and electrostatic force. The positive charge of the outer part is attracted to the negative charge of the inner part. This setup creates an electric field that concentrates the majority of the electric field in the oxide layer.

The strong electric field created by this construction enables a greater capacitance per unit volume than other types of capacitors, however durability is sacrificed due to the effects of time, temperature, and humidity. In order to counteract these effects, the E36D451HPN152TED0M is designed with a self-healing mechanism. In short, a failsafe mechanism is present that is triggered when unexpected currents and voltages cause a breakdown in the dielectric’s electric field. When this happens, the excess current is bled off, and the capacitor’s cathode material reforms the oxide layer and restores the capacitor’s functionality.

The E36D451HPN152TED0M is optimized for use in automotive conditions, featuring a wide range of capacitance, high ripple current rating, and excellent ESR performance. This makes the E36D451HPN152TED0M suitable for a wide range of automotive applications, including hybrid and general automotive module and system applications. Its cycling capability also makes it suitable for use in controllers, where many cycling cycles are needed.
