It is suitable for use in low frequency memory systems, such as SRAM and DRAM. It is an ideal choice for use in military equipment, wireless or cellular communications devices, and automotive applications.

The TRJA105K025RRJ also has applications in portable audio devices, video gaming consoles, robots, and other consumer devices. It offers excellent temperature stability with a 40°C to 125°C operating temperature range and a -55°C to +150°C storage temperature range. It is RoHS compliant and is available in various surface mount designs.

Working Principle

The TRJA105K025RRJ is a tantalum electrolytic capacitor with a liquid electrolyte. In this type of capacitor, the anode is made from tantalum, which is an element with a very high electrical conductivity. The cathode is usually made from an oxide, such as manganese dioxide or an activated charcoal. A liquid electrolyte is then used to connect the anode and the cathode.

When a voltage is applied to the capacitor, the electrolyte creates an electric field in between the anode and cathode. This field causes anions (negatively charged particles) to move through the electrolyte and collect at the anode. Simultaneously, the electrons will flow to the negative electrode and create a charge on the anode. The capacitor will store this charge until the voltage is removed.

The TRJA105K025RRJ is known for its high reliability and long-term performance. It is a low profile capacitor with a low equivalent series resistance (ESR) and a low capacitance drop at high frequencies. The components are designed to have an extra-long life span, and the capacitors have an extremely low leakage current. The low profile design and the high temperature range make these types of tantalum capacitors an ideal choice for low profile and high temperature applications.

Conclusion

The TRJA105K025RRJ is a common type of tantalum capacitor that is available in a wide range of values and is used in a variety of applications where weight and temperature are of major concern. It has a low capacitance drop at high frequencies and an extremely low leakage current, making it an excellent choice for use in circuits where electrical noise must be reduced. The tantalum anode and liquid electrolyte of the capacitor work together to create an electric field that causes anions to move through the electrolyte and collect at the anode while electrons flow to the negative electrode and create a charge on the anode.
