Through Hole Resistors are a type of resistor that has a lead wire mounting so that it can be placed in a through hole on a printed circuit board. The SFR2500001433FR500 is a package type through hole resistor, which belongs to the family of higher power resistors. The package size of this freedom series is 105 mils thick, 0.25” long and 0.25” wide.

The main task of a through hole resistor is to limit the current in a circuit and to maintain a specific voltage. It is a passive component that usually functions as a temperature-dependent variables, and is commonly used in a variety of applications from power supply, motor control, radio and digital circuitry to heating and lighting.

The application field of SFR2500001433FR500 lies in industrial equipment, oil and gas exploration, power generation and circuit protection. Its maximum power rating is 28W and its resistance range is 0.1ohm to 10Kohm. It can endure peak temperature up to 175℃, making it suitable for extended operating temperatures and with high pulse loads.

SFR2500001433FR500 is constructed around a cast aluminum body that is coated with glass-filled epoxy. The frame consists of two thin sheets of foil which are separated by a soft ceramic substrate. The lead wires are then affixed to the substrate using a thermal fuse. The substrate is then treated with a thermally conductive paste, which serves to rapidly dissipate heat from the resistor.

SFR2500001433FR500 works through an effect called ‘resistive heating’. In this effect, the resistor element changes the electrical energy into heat, which then dissipates into the environment. The rate at which this conversion takes place depends on the level of resistance of the resistor. As such, the greater the resistance of a resistor, the more heat it will generate.

The inherent inductance of the resistor also plays a role in affecting its performance. The package size of this resistor helps to reduce its inductance, ensuring that it is capable of operating within its rated parameters. It also helps to reduce thermal and electromagnetic interference, further increasing its efficiency.

The SFR2500001433FR500 is a reliable and robust resistive element that can be used in a wide variety of applications. It is shock and vibration resistant and offers a high level of safety. Its broad resistance range and high power rating, as well as its impressive thermal characteristics, make it an excellent choice for various electric applications.
