Tantalum capacitors are widely used electronic components, and they become especially popular when the devicessuch as mobile phones become smaller and lighter. The T86D686M016EAAL is a radial leaded tantalum capacitor from AVX Corporation. This capacitor is a high reliability wet tantalum solution housed in case T86 and is an extended radial product. It has an anode made of tantalum core, cathode made of manganese dioxide, and an electrolyte which is formed in the hermetic sealing ceramic-to-metal (CeramTec) feedthru.

Application Field

T86D686M016EAAL is popular in many electronic circuits. First of all, it can be used in consumer electronics applications, such as mobile phone, tablet and laptop. Besides, it can be used in military and aerospace applications due to its high reliability. It can also be found in automotive electronics, such as engine control module, airbags and brake module, as it has a excellent temperature cycling performance. Last but not least, it is a ideal component for medical instruments and equipments, like ECG monitor, blood pressure monitor and MRI scanner, due to its long life.

Working Principle

The T86D686M016EAAL is a tantalum electrolytic capacitor, which works by relying on an conducting anode surface covered by a layer of oxide. When it is connected to the DC circuit in positive and negative poles, the electric field across the oxide layer will cause electrons to move from anode to cathode unidirectionally and accumulation of charge occurs on both terminals. This charging process will create an electric storage effect and voltage is stored between terminals. During the discharging process, voltage is released and current will flow from cathode to anode.

In a T86D686M016EAAL, anode is made of tantalum core and cathode is made of manganese dioxide. All these materials used in a T86D686M016EAAL are much more reliable than the ones used in other capacitors, which make the T86D686M016EAAL more suitable for the applications mentioned before, especially for consumer electronics and medical instruments. Also, the hermetically sealed ceramic-to-metal (CeramTec) feedthru prevents oxygen and moisture to enter the capacitor, which allows the T86D686M016EAAL to operate effectively and reliably in extreme temperature and environmental conditions.

In conclusion, the T86D686M016EAAL from AVX Corporation is a radial leaded tantalum capacitor, and is a popular choice for consumer electronic, automotive, aerospace and medical device applications. It has an anode made of tantalum core, cathode made of manganese dioxide, and an electrolyte which is formed in the hermetic sealing ceramic-to-metal (CeramTec) feedthru. Its capacitance is stable with changes of temperature and frequency, which makes it a ideal device for long-term applications.
