Through Hole Resistors

Through hole resistors are components used in electronic circuits for managing the current and voltage in a circuit. The terminals of each resistor are extended into the hole on the printed circuit board where they can be soldered into the circuit. The through hole resistor embodies a strong impedance which value can be changed by the selection of a particular type. The widely used through hole resistor is RSF50SJR-52-1M5.

RSF50SJR-52-1M5 application field and working principle

RSF50SJR-52-1M5 is a popular type of through hole resistor, widely applied for the temperature resistance in various electronic circuits. It is composed of carbon film resistors and has a complete range of types. It features small size, wide temperature range, low temperature drift, and strong overload capacity.

When operating, RSF50SJR-52-1M5 expels heat to the resistance element inside itself. The electricity is looped along the circuit board and, in the meanwhile, two terminals of the resistor will be connected to the voltage source and the load respectively. As the current flows through, the energy of the current generates heat and is partially expels to the external environment while also passing through the carbon film of the resistor. The higher the current, the more powerful the heat disperses, thus, forming resistance against the current within the circuit and protecting other components from being affected by the voltage saturation.

RSF50SJR-52-1M5 also supports higher current rates with far better load capacity compared to other resistors. It possesses anti-vibration, anti-corrosive and anti-jamming capability with excellent temperature characteristics. It can operate at both high & low temperature with a linear deviation of 15~20ppm/°C.

Moreover, it also provides technical supports on temperature-related protection over temperature range. Under extreme temperature, the resistor will not malfunction or explode. The overload protection of its element significantly reduces the risk of fire and electric shock, making it much safer than ordinary resistors.

Coupled with a higher current load capacity and excellent temperature characteristics, RSF50SJR-52-1M5 is ideal for use in wide varieties of electronic applications for controlling current and voltage in a circuit. Examples include powering up transformers, motors, and rectifiers for industrial control, flasher units, electricity heaters, and other high-current systems.
