Through Hole Resistors

H432R4BYA Application Field and Working Principle

Through hole resistors are essential components in the electronic circuit for controlling and limiting current flow and providing electrical isolation. The H432R4BYA is a popular through-hole resistor with a rated voltage and power handling capacity much higher than many of its competitors. This makes it the preferred choice of many electronics engineers for their resistive applications.The H432R4BYA is a through-hole axial-leaded resistor, with its lead wire going through the body of the resistor. This is a very common type of through-hole resistor and can be easily mounted to a PCB board for reliable connection. The electrical characteristics of this resistor are defined by its resistance value, tolerance, and temperature coefficient that are marked on the body of the resistor. Generally, resistors of this type are manufactured with 4 or 5-digit numerical codes such as the H432R4BYA.The H432R4BYA through-hole resistor features a high-temperature, high-capacity ceramic powder composite, with a resistance value of 4.32 ohms. The resistance value is printed on the top surface of the resistor, along with its tolerance, temperature coefficient, and other useful information. The resistor has an operating temperature range of -55 to +85℃ and a working voltage of up to 250V instantly. Its insulation resistance is greater than 100M ohms, making it suitable for use in high-frequency applications. The power handling capacity is 175mW, making it suitable for use in a variety of medium power applications. The H432R4BYA works by providing a fixed resistance to the current flow, in conjunction with all other components in the circuit. When a voltage is applied to one side of the resistor, an equal amount of current will flow through the resistor and out of the other side. This current flow will be limited by the resistance value and other values, such as its temperature coefficient and tolerance range, will affect how much current can flow through the resistor. The H432R4BYA is typically used as a limiter in current-limiting applications such as power supply regulation circuits and thermal catastrophe protection circuits. It is also used in voltage-regulating circuits such as isolated DC-DC Converters. The H432R4BYA is ideal for applications where a high voltage or high current is required while still maintaining a small form factor, such as DC motor control circuits.Overall, the H432R4BYA is a popular through-hole resistor that is used for a variety of applications due to its high-temperature, current-handling capacity, and its small form factor. Its high-quality construction ensures that it will provide stable and reliable performance.
