Through Hole Resistors are one of the most common types of resistors used in electronic circuits. H4249KBCA is a special three-terminal resistor with a wide power range and a great tolerance rate. It takes advantage of a monolithic structure to achieve a very small size directly mounted over a printed circuit board (PCB). This type of resistor is often used in power control, overload protection and impedance matching applications.

The H4249KBCA offers mechanical flexibility, high reliable performance and low thermal stability. It features four resistive elements separated by two positive current terminals and one negative current terminal. It also has an adjustable heatsink device to prevent overheating. The power ratings are from 2 W to 25 W, the wattage is programmable and the temperature coefficient ranges from 25 ppm/°C to 200 ppm/°C.

The working principle of the H4249KBCA is simple. The resistor is placed between three current terminals and then grounded. When a current passes through the resistor, a voltage drop is created across the resistor. This voltage drop then causes a current to flow through the resistor, which results in the dissipated heat. The temperature coefficient of the resistor is determined by how much the resistance value changes with a change in temperature.

The H4249KBCA is a great option for applications that require high tolerance and accurate control of power. It is often used in the automotive industry, consumer electronics, LED lights, medical systems, communications systems, and electric power systems. It is also frequently used in industrial and military applications.

Using the H4249KBCA in a circuit allows for improved reliability and accuracy, while the adjustable heatsink device ensures better thermal management. The H4249KBCA is an excellent choice for applications that require precise current control and reliable performance. The monolithic structure allows for a small form factor and is one of the reasons the H4249KBCA is so popular in the electronics industry.
