Tantalum capacitors are the most reliable and efficient electrical components for providing the necessary power for electronics and appliance functionality. A wide variety of tantalum capacitors are available on the market, each one having its own unique application field and working principle.The 199D685X0020C1V1 is one such tantalum capacitor specifically designed to be used in automotive electronic control units (ECUs) due to its ability to provide low noise, low ripple and long-term reliability. It is a wet emergency dual-phase type capacitor offering a range of values from 2.2 to 2.7 μF and rated voltage of 20V. The low impedance design, which comes with a temperature rise guarantee of -40°C to +105°C, has the ability to withstand a large number of start/stop cycles or a single extended burst of pulses.The 199D685X0020C1V1 has been implemented in a wide range of automotive applications such as engine controllers, flowmeters, airbag controllers and fuel and ignition systems. With its high ripple current, it is ideal for applications that require quick and reliable switching and response times. It also finds use in DC-to-DC converters for eliminating voltage drops, as well as in voltage-stabilized supply loops as part of the output filtering stage.The working principle of the 199D685X0020C1V1 is based on the storage of electrostatic energy derived from the collector charge generated when voltage is applied across the electrodes. This charge induces an electrical field which, in turn, generates a capacitive reactance. This reactance is responsible for storing the energy in the form of electric fields.The 199D685X0020C1V1 consists of an anode, a cathode and an electrolyte. The alternating current and voltage applied to the capacitor, enters through the electrolyte and is divided into two parts – a current and voltage connecting the anode and cathode and the capacitive reactance between them. This is where the energy is stored, which is then released when the capacitor’s terminals are open-circuited and the electrical energy is dissipated in the form of heat.In conclusion, the 199D685X0020C1V1 capacitor is a reliable and efficient component suitable for a wide range of automotive applications, such as engine controllers, flowmeters, airbag controllers and fuel and ignition systems. Its ability to provide low noise, low ripple and long-term reliability makes it an ideal component to store electrostatic energy and dissipate electrical energy in the form of heat.
