Tantalum Capacitors: M39006/09-8169 Application Field and Working Principle

Tantalum capacitors are widely used in a variety of applications due to their ability to withstand both high temperature and mechanical shock. These capacitors are available from various manufacturers and include the M39006/09-8169 series, which are particularly well suited for use in space, military and other harsh environments.

Tantalum capacitors typically consist of a precious metal cathode (typically tantalum pentoxide) sandwiched between two solid pieces of metal. The metal electrodes on either side of the cathode are able to store and quickly release electrical charge, making tantalum capacitors an ideal choice for applications where high capacitance and fast charge/discharge times are needed. They are also typically smaller and lighter than other types of capacitors.

The M39006/09-8169 series of tantalum capacitors is of particular interest due to their advanced durability and longevity. These capacitors possess a greater tolerance to high temperature and shock than other standard tantalum capacitors, making them an ideal choice for applications in extreme environments. In addition, they offer a surprisingly low equivalent series resistance (ESR) which is further enhanced through the use of “soft termination” technology, allowing them to be used in even more demanding applications.

The M39006/09-8169 series of capacitors is capable of storing charge at up to a maximum voltage of 27 volts, while sustaining a 12 volt ripple current. The capacitance range is available from 2.5 uF up to 180 uF, and the series also features low ESR values and tolerances of ± 20 %. These features make them an ideal choice for use in smps, uninterruptible power supplies (UPS), high power switching power supplies as well as other applications.

The working principle of a tantalum capacitor is rather simple. When an electric current is applied, electrons are attracted to the cathode, thus creating a positive charge on the anode and negative charge on the cathode. When the amount of charge reaches a certain level, an electric field is produced within the capacitor, which causes a voltage drop within the capacitor. This voltage drop is used to store electrical energy in the form of a charge. When the external voltage source is removed, the voltage drop will cause the charge to flow back through the circuit.

The M39006/09-8169 series of capacitors is ideal for applications that require high capacitance and high power ratings in an environment that is characterized by high temperature and shock. Their excellent ESR ratings coupled with their advanced soft termination technology make them an ideal choice for use in smps, UPS, high power switching supplies as well as other harsh environment applications. They are also available from a wide range of manufacturers with various capacitance ratings, voltage ratings, and ESR ratings, so it’s easy to find the perfect capacitor for any application.
