Tantalum Capacitors

TRJB685K025RRJ is a kind of the tantalum capacitor. It is a device which is composed of two metal plates separated by a dielectric material. The plate on one side is referred to as the anode, while the plate on the other is referred to as the cathode. The dielectric material is usually made up of tantalum oxide.

Application Field and Working Principle

The TRJB685K025RRJ tantalum capacitor is widely used in a variety of industries, such as consumer electronics, automotive, industrial, medical and military. They are very effective for energy storage, filtering, and buffering purposes when reliable and low dissipation is required.

The working principle of the tantalum capacitor is based on the capacitive behavior of a capacitor. When a voltage is applied, the dielectric material between the plates forms a barrier, preventing the flow of current. This creates a steady-state charge, which forms the capacitance of the capacitor. This capacitance is then used to store and release the energy needed for a particular application.

Tantalum capacitors are much different than the normal aluminum electrolytic capacitors. The anode of a tantalum capacitor can be either a solid surface or an electrolyte solution. In the electrolytic type, the anode is made up of an electrolyte solution while the cathode is a solid material. The electrolyte solution absorbs and stores the electrical charge.

The major advantages of the tantalum capacitors include high capacitance, low leakage and excellent temperature stability, high ripple current handling capability, and high energy density. Furthermore, the capacitance value does not change significantly, even for small changes in voltage, hence, the effect of temperature on the capacitor is relatively insignificant.

In addition, the a tantalum capacitor is highly reliable and long lasting. It has a wide operating temperature range and its performance is not affected significantly by long-term exposure to high temperatures and humidity. Furthermore, due to its excellent electrical characteristics, it is well suited for use in medical and military applications where accuracy and reliability are critical.

The TRJB685K025RRJ tantalum capacitor has a voltage rating of 25V and a capacitance of 6.85uF. It is rated for a maximum operating temperature of 105°C, and the operating temperature range of the device is from –40 to +105°C. It has a maximum dissipation factor of 0.02 and a maximum ripple current of 1.7 A.

In conclusion, the TRJB685K025RRJ tantalum capacitor is a device that can be used for a variety of applications where reliable and low dissipation is required. It is highly reliable, long lasting, has a wide operating temperature range, is highly temperature stable and can handle high ripple currents with ease. The device is an excellent choice for use in medical and military applications where accuracy and reliability are critical.
