TAJE477K004RNJ

A tantalum capacitor is a kind of electrolytic capacitor, made up of a pellet of tantalum metal on which an oxide layer is formed at high temperatures. The tantalum capacitor has several advantages compared to other types: it is a miniature engineering component, it has a long life and excellent temperature resistance, and it has very good capacitance accuracy. The TAJE477K004RNJ is a particular type of tantalum capacitor that utilizes a molded case construction with a niobium outer layer and an anode wire of molybdenum alloy. This makes the TAJE477K004RNJ resistant to corrosion and other types of physical damage.

The TAJE477K004RNJ is a surface mount device with a maximum case diameter of 4.7mm and a profile height of 4.1mm. The device has a voltage rating of 4V and a capacitance of 4,700uF with a tolerance of +/- 20%. The device also has a temperature coefficient of -50 +/-20ppm/°C and a temperature range of -55°C to +125°C.

The TAJE477K004RNJ has a wide range of applications in the electronics industry. It is commonly used as a filter in power supply designs, where it is used to eliminate any noise from the supply. It is also used in the audio industry as a buffer between stages of amplifiers, allowing signals to pass through without distortion. Other applications include the regulation of voltage, the protection of electronic components from overvoltage, the storage of power in memory systems, and the smoothing of pulses in high-tech applications.

The TAJE477K004RNJ operates on the principle of a dielectric that stores electrical energy in the form of an electrostatic field. This electrostatic field is created and maintained by a voltage difference between two conductive plates. When a voltage is applied to the device, a current flows through the dielectric and is stored in the form of an electrostatic field. The amount of charge (or capacitance) that the device can store is determined by the amount of dielectric material between the plates and the thickness of the dielectric.

In summary, the TAJE477K004RNJ is a type of tantalum capacitor with a wide range of applications in the electronics industry. It has a molded case construction with a niobium outer layer and a molybdenum alloy anode wire, which makes it resistant to corrosion and other types of physical damage. The device is usually used as a filter or buffer in power supply designs and amplifier stages, and it operates on the principle of a dielectric that stores electrical energy in the form of an electrostatic field.
