Through Hole Resistors are electronic components used to regulate current in a circuit. They work by limiting the amount of current that can pass through them and are an essential part of any electronic device. The CPW03R4020FB313, a Through Hole Resistor, is widely used in a variety of industrial, commercial and consumer devices such as automotive electronics, white goods, Uninterruptible Power Supplies (UPS), and voltage regulators.The CPW03R4020FB313 is a Through Hole Resistor with a maximum rated power of 0.25 watts. It has an operating temperature range of -55°C to 155°C, and a thermal resistance of 1.1°C/W. It has an aluminum-nitride low-induction core, a 10 – 30ppm/°C temperature coefficient of resistance (TCR) and a maximum working voltage of 500V. It is typically available in a variety of resistance values from 0.1Ω to 4.99MΩ.The resistance of a resistor is measured in ohms and is determined by the amount of resistance it provides when connected to a circuit. When a resistor is connected to a circuit, it will reduce the amount of current that can flow through it, allowing the voltage to be regulated and preventing damage to the components. When selecting the correct resistor for a specific application, the amount of resistance that is needed must be determined. This will depend on the voltage that is to be regulated and the amount of current that must be limited.The CPW03R4020FB313 has been especially designed for demanding applications, such as automotive electronics, white goods, Uninterruptible Power Supplies (UPS) and voltage regulators. Its aluminum-nitride low-induction core, 10 – 30ppm/°C temperature coefficient of resistance (TCR) and 500V maximum working voltage make it suitable for use in high temperature and high voltage applications. Additionally, its rated power of 0.25 watts allows it to handle a maximum power of up to 0.4 watts for short periods of time without damage.The working principle of the CPW03R4020FB313 is simple. When it is connected to a circuit, the resistor will limit the current flow, thus regulating the voltage. This ensures that the components on the circuit are not damaged by excessive current flow or too large of a voltage drop. The resistor itself does not dissipate any energy, as the current flow through the resistor does not cause any heat.In conclusion, the CPW03R4020FB313 is a Through Hole Resistor specially designed for demanding applications such as automotive electronics, white goods, Uninterruptible Power Supplies (UPS) and voltage regulators. Its maximum rated power of 0.25 watts, aluminum-nitride low-induction core, 10 – 30ppm/°C temperature coefficient of resistance (TCR) and 500V maximum working voltage make it ideal for use in high temperature and high voltage applications. The resistor limits the current flow providing voltage regulation, ensuring that the components on the circuit are not damaged by excessive current flow or too large of a voltage drop.
