Tantalum Capacitors

Tantalum capacitors are one of the most common types of capacitor used in electronic circuits, and are a type of electrolytic capacitor. These capacitors are constructed from two electrodes: an anode and a cathode, separated by an electrolyte, usually tantalum pentoxide. They are a type of capacitor that offers high capacitance in a relatively small package, and are particularly popular in consumer electronics, communications and audio applications.

TRJA226M006RRJ Application Field and Working Principle

The TRJA226M006RRJ is a TANTAMOUNT-series surface-mount tantalum capacitor, manufactured by KEMET, a leading manufacturer of capacitors. The TRJA226M006RRJ is an “Ultra-High Reliability, Automotive Grade” capacitor, suitable for use in a wide range of automotive applications, such as antilock brake systems and airbag deployment. It features a high-temperature, low-ESL-capacitance design, with an operating temperature range of -55°C to 125°C.

The TRJA226M006RRJ capacitor is designed specifically for automotive applications, meaning that it is capable of withstanding higher temperatures and prolonged vibration, whilst still performing at a high level of reliability. How does it achieve this? This can be explained through a look at the capacitor’s working principle.

Tantalum capacitors work on an electrolytic principle, using ions to achieve their electrical effect. An electrolytic capacitor consists of two conductive plates, separated by a thin dielectric layer. The dielectric is usually made from a combination of liquid electrolyte and tantalum pentoxide, which is a semipermeable ceramic material. When a voltage is applied to the capacitor, it causes the liquid electrolyte to polarize, creating a thin layer of ions on the plates. This layer of ions acts as a charge store and allows the capacitor to store a large amount of charge.

The TRJA226M006RRJ is capable of withstanding temperatures up to 125°C and is designed to be used in applications that may be exposed to high levels of vibration. To achieve this, the capacitor is built with a “low ESR” design, meaning that its equivalent series resistance (ESR) is minimized for optimal performance in high-vibration environments. In addition to this, the capacitor also features an extremely reliable construction, ensuring that it will continue to perform at a high level of safety and reliability.

Overall, the TRJA226M006RRJ is a highly reliable and robust capacitor, designed specifically for use in automotive applications. It features a high-temperature, low-ESR design, making it suitable for even the toughest automotive applications.
