Through Hole Resistors

A through hole resistor is a electrical component with resistor characteristics meant for the application in through hole technology. It is mainly used to adjust currents and divide voltages in electronic circuits as well as it can be used to reduce interference and prevent voltage spikes. The through hole resistor consists of two leads of metal extending from the component body. This allows the resistor to be inserted into a printed circuit board (PCB) and electrically connected by soldering the leads into the appropriate holes.

RNX0501M20FKR8 Application Field and Working Principle

RNX0501M20FKR8 is a through hole resistor with 5% tolerance and 1/10W power rating, with plastic case and caps encapsulated on the outer surface for insulation. It is widely used in wide range of electronics, like control systems, power supplies, and various kind of instrumentations. The working principle is simple, as it acts as a resistor, it provides resistance and regulates current flow when a potential difference is applied.

In normal operation, the resistance of the resistor will remain constant, but factors like temperature will affect it to vary a little amount. Thermal coefficient of resistors refers to the resistance variation due to temperature change. In this product, its value is approximately -50 ppm/°C, which is very near to zero and it makes the resistor to be stable in temperature.

Furthermore, this type of resistor does not actually dissipate energy. Instead, the resistor will convert the potential energy into heat and make the resistor warm. Its temperature rise in normal ambient temperature should not exceed specified limits and also the life time of the resistor depends on the ambient temperature and power rating.

Last but not least, RNX0501M20FKR8 uses special wire materials, which helps the product has a low noise even for high frequency circuits. Low noise is due to the strong anti-interference ability and it offers more reliable performance. In addition to noise and anti-interference, the component has other important advantages like quick response, low load capacity, and wide voltage adaptive range.
