Overview of Aluminum - Polymer Capacitors

Aluminum - polymer capacitors, also known as polymer aluminium electrolytic capacitors or aluminum electrolytic capacitors, are electrical components whose capacitance is larger than that of conventional electrolytic capacitors while taking up a much smaller volume. They were first released during the late 1990s and quickly gained high popularity in the commercial market due to their smaller size, lighter weight, improved reliability, and extended lifespan. They have since become an essential component in applications ranging from consumer electronics to (35SEF39M) medical and industrial devices.

These devices are categorized as part of the electrolytic capacitor family of components and are constructed with a solid aluminium electrolyte centre surrounded by a special polymer, usually polyvinylidene fluoride (PVDF). The polarization of the electrodes, plus their arrangement within the device, leads to the segregation of charges on opposite sides of the interface, giving them the capacity to store energy.

35SEF39M Application Field and Working Principle

The 35SEF39M, developed by Nichicon Corporation, is a type of aluminum - polymer capacitors specifically designed for use in automotive, usage in power conversion and control, and the photocopier and printing market. It offers a wide range of sizes and capacitance values, ranging from 10 uF to 1000 uF, and is rated and approved under the standards of the Automotive Electronic Council (AEC-Q200) for automotive and heavy-duty applications.

Working on the same principles as traditional electrolytic capacitors, the 35SEF39M is constructed by sandwiching a solid aluminium electrolyte between two metal end plates. This sandwich is then encapsulated within a special PVDF polymer, creating a well-insulated structure. Since aluminum electrolyte has a naturally large strain energy, this structure generates a higher electrical field than conventional capacitors. Combined with their smaller size and lighter weight, this allows for more power to be stored in a much more compact package.

When electricity passes through the capacitor, its electrodes start to polarize. This polarization creates an electrostatic field in the cavity of the capacitor, which is further strengthened by the use of a special PVDF polymer. It is this change in electrostatic field that allows the capacitor to store energy.

Capacitance of the 35SEF39M is determined by the thickness of the polymer, the distance between the electrodes, and the area of the two electrodes. As the manufacturing process is quite optimized and the dimension tends to be quite uniform across components of the same series, the capacitance of the 35SEF39M is quite stable regardless of voltage or temperature variations.

The 35SEF39M is also constructed with a conductive polymer, making it more resistant to electrical leakage than other aluminum electrolytic capacitors. This ensures higher reliability and stability in high voltage applications.

Additionally, the 35SEF39M is a highly tolerant device, meaning it can better resist short circuits and other electrical anomalies compared to traditional capacitors. This enhanced tolerance makes the 35SEF39M ideal for use in automotive applications, as well as power conversion and control, and photocopier and printing markets where electrical fluctuations are common.

Conclusion

The 35SEF39M is a type of aluminum - polymer capacitors developed by Nichicon Corporation. It is capable of storing larger amounts of energy than conventional electrolytic capacitors while taking up a fraction of the space. Due to its smaller size and lighter weight, higher tolerance to electrical leakage and anomalies, and its relative stability, the 35SEF39M is now commonly found in automotive, power conversion and control, and photocopier and printing markets.
