Tantalum CapacitorsTantalum capacitors are omnipresent in a variety of electronic applications and, due their low ESR, wide operating temperature range and a huge variety of case sizes, can be adapted into almost any design. In this article we will discuss the application field and working principle of 4-1879063-6 Tantalum capacitors.Tantalum capacitors are commonly used in power supplies, circuit protection, filtering, decoupling, and buffering applications. In these applications, their extremely low ESR, low leakage current, and very small capacitance variation over the wide temperature range, making them ideal for use in many different types of electronic circuits.The 4-1879063-6 Tantalum capacitors are a variant of the tantalum capacitor, which uses a solid electrolyte of tantalum pentoxide instead of a liquid electrolyte. This reduces the ESR and increases the capacitance of the device. The tantalum pentoxide also provides a higher dielectric constant, leading to a higher capacitance per unit volume of the device.The equivalent circuit of a tantalum capacitor is composed of an anode, a cathode, and two capacitors in parallel. The anode is connected to the circuit ground, while the cathode is connected to the circuit power source. A pair of capacitors in parallel form the equivalent circuit of a tantalum capacitor, with the anode capacitor forming one side of the equivalent circuit, and the cathode capacitor forming the other side.Due to the electrolyte at the anode, the anode side of the device will have an effective series resistance (ESR) of around 0.1 ohms, while the cathode side will have an ESR of around 0.01 ohms. These values are important, as they determine the amount of current the device can supply without significantly affecting the AC equivalent series resistance (AC ESR) of the device.The 4-1879063-6Tantalum capacitor is a single-ended capacitor, meaning it only has one terminal. This single terminal is then connected to the circuit power source, and the other side of the device is connected to the ground of the circuit. Due to this single-ended configuration, the capacitor is usually used as a bypass capacitor in a switching power supply or a UPS.The 4-1879063-6 series of tantalum capacitors have a capacitance range of 1 – 100V, an operating temperature of -40°C to 85°C. The rated ripple current is 1.2A, and the maximum ripple current is 2A. The rated ripple voltage is 50mV, while the maximum ripple current is 120mV.One of the main advantages of 4-1879063-6 capacitors is their low ESR, which leads to better power conversion efficiency, as less power is lost in the form of heat. Another advantage is their wide operating temperature range, meaning they can be used in applications that require a wide range of temperatures.In conclusion, 4-1879063-6 Tantalum capacitors are ideal for a wide variety of electronic applications due their low ESR, wide temperature range, and high capacitance per unit volume. They are used in power supplies, filtering, decoupling and buffering applications in both single-ended and differential configurations and are capable of providing clean, stable power and low ESR to many circuits.
