Tantalum Capacitors are widely used in an array of industries. This article looks at the M39003/01-8217H application field and working principle.

Tantalum capacitors are polarised electrolytic capacitors featuring a solid Ta-Oxide film as one of the electrical layer materials. This solid dielectric enables the design of capacitors with a higher volumetric efficiency and a low ESR (Equivalent Series Resistance).

M39003/01-8217H is a type of Tantalum capacitor which has been specifically designed for use in avionics applications including airframes and other high-reliability systems. Its\' longterm stability and improved reliability make it ideal for use in these types of applications.

This particular type of capacitor features a case made of nickel-plated molybdenum and an oxide-coated lead frame. Moreover, two pre-moulded seals are designed to ensure an effective interface. This offers superior protection against moisture, a key factor in avionic systems.

Regarding the capacitor\'s working principle, the method by which a tantalum capacitor store electrical charge involves an electrolyte and a cathode material. When a voltage is applied, the electrolyte undergoes an ionic reaction, leading to a difference in electrical potential between the electrodes. This difference in electrical potential makes the electrolyte highly conductive.

In contrast to other types of capacitors, the operation of a tantalum capacitor is reversible. Thus, the electrolyte in the capacitor can be reversibly oxidised or reduced. This process helps to maintain the capacitor\'s electrical charge and also helps to combat leakage.

The M39003/01-8217H capacitor features an operating and storage temperature range of -55°C to +125°C. This impressive temperature range makes it particularly suited to applications in temperature extremes. It is also worth noting that this type of capacitor has a maximum ripple current of 560mA, which is particularly useful for circuit applications that create high frequency ripple currents.

In summary, the M39003/01-8217H is a type of Tantalum capacitor designed for use in avionic applications. Its\' high temperature range, longterm stability and improved leakage prevention make it ideal for use in highreliability systems. Additionally, its\' maximum ripple current of 560mA makes it suitable for circuits experiencing high frequency ripple currents.
