Through Hole Resistors

Resistors are essential electrical components that control current flow in a circuit. In many electronic device designs, it is important to be able to accurately measure and adjust the flow of current. Through-hole resistors are one type of resistor that are used to achieve this. This type of resistor is usually mounted on a circuit board from the backside of the board by soldering its two lead connections. One type of through-hole resistor is the RN70D2740FBSL series resistor, manufactured by Ohmite. These are carbon film through-hole resistors with axial leads, contained in a 3.2 mm body. They are non-inductive and suitable for high power applications in consumer and automotive electronics. The RN70D2740FBSL series resistor has a power rating of 7 watts resistors. It has very low noise and stable performance. Its axial leads are made from a high heat capacity alloy for better heat and aging stability. Its unique molded profile and heat dissipating ribs, allow the axial leads adequate ventilation and heat dissipating, while providing better connection protection. Its high temperature range of -55 C to +180 C degrees meets modern electronic requirements. The RN70D2740FBSL resistor, is available in standard E12 and E24 values. Its E12 values range from 10 ohms to 4.7K ohms, while its E24 values range from 4.75 ohms to 47K ohms. It is important to note that there may be a slight deviation in tolerance from the marked resistance value, usually no more than 5% for any given resistor with an E12 value. The main application field for the RN70D2740FBSL resistor is consumer and automotive electronics. It can be used for AC drivers, amplifiers, inverters, and voltage and current control applications. It is also commonly used for power control circuits, emergency lights, and overvoltage/overcurrent protection circuits. The working principle of a through-hole resistor is based on the concept of electrical resistance. Electrical resistance is the measure of the opposition that a resistor produces to the flow of electric current. Resistors are constructed with a material that resists current flow. This resistance is determined by the structure and physical characteristics of the material being used. In the case of an RN70D2740FBSL resistor, the material is carbon film. As electrons move through this material, it is resisted and the flow of current is reduced. The RN70D2740FBSL series resistor is a widely-used, cost-effective solution for controlling current in a variety of consumer and automotive electronic applications. Its high power rating, high temperature range, and low noise and stable performance make it an excellent choice for designers looking for a reliable and efficient component.
