Tantalum capacitors are electronic components consisting of a tantalum metal anode, an oxide dielectric layer, and a solid manganese dioxide conducting cathode. The TLJA476M010R0600 is the standard reference material model, and the features of it make it a good fit for applications requiring very low leakage, long life, and high capacitance. Below, we will discuss this capacitors’ application fields as well as its working principle.

Application Field

Due to their low operating voltages, long operating lifetimes, and high capacitance values, the TLJA476M010R0600 is an ideal choice for power supply solutions, where industry standards demand low EMI, heat resistance, and reliable 24/7 operation. This type of capacitor is often found in cell phone components and data centers, where it is used for buffering and decoupling. Its robust construction also makes it an excellent choice for high-end avionics and military applications, where it can handle temperatures up to +125°C and vibration/shock up to 30G.

Working Principle

The TLJA476M010R0600 uses the same basic principles of capacitance as any other capacitors. It features an anode made of tantalum metal, which is separated from the cathode by a layer of tantalum oxide dielectric. Applying power to the electrode causes electrons to move and accumulate on the anode. The charge is then stored in the layer of dielectric and the capacitor becomes polarized. The capacitor then discharges when Voltages of the opposite polarity is applied. Essentially, a tantalum capacitor is a semiconductor device — current between the anode and cathode can only flow via the dielectric. Depending on the design and size of the capacitor, its electrical characteristics, such as voltage drop and leakage current, can vary.

Conclusion

The TLJA476M010R0600 is a type of tantalum capacitor, which offers low voltage operation, high capacitance, and long service life. It is a suitable choice for applications needing low EMI, heat resistance, and 24/7 operation. It uses the basic capacitance principles, with a tantalum metal anode, dielectric layer, and manganese dioxide conducting cathode. Its electrical characteristics, such as voltage drop and leakage current, depends on the design and size of the capacitor.
