Through Hole Resistors are an essential component commonly used in various electronic circuits. Popularly available in the form of wirewound, fixed or adjustable, they are used with or without a circuit board. RWR80S16R5FRRSL is an example of a wirewound resistor designed for the through-hole technique, which is described in the following sections.

Application Field of RWR80S16R5FRRSL

RWR80S16R5FRRSL is a through-hole wirewound resistor and is suitable for a variety of applications, such as precision voltage regulation, current sensing and pulse loads. The fixed resistors are applied in the applications requiring long-term stability and high power ratings and are able to handle higher temperature and power dissipation.

These resistors are compatible with the EIA standard packages such as TO-220 (for high power applications), TO-92 (for low-power to medium-power applications), and TO-247 (for high-power applications). The resistors also feature a flame retardant capability and provide a smoother finish.

Wirewound resistors are used in power sources, cellular systems, radio systems, SMPS controls, UPS systems, automotive power systems, and LED lighting. One of their major advantages is that they are consistently reliable, and have low voice, high power ratings, and good temperature stability.

Working Principle

The working principle of a wirewound resistor is pretty simple. It is composed of two end terminals, one of which connects to the power source and the other is connected to the load. In between the two ends, there is a wire made of copper or some other low-resistance metal, usually coated in a layer of insulation. This layer of insulation allows the current to flow through the wire without shorting the resistor.

When the power source is switched on, a high voltage spark gap is created between the two terminals and the current flows through the wire. When the current passes through the wire, it dissipates in the form of heat energy due to the resistance of the wire. This heat energy is what gives the wirewound resistor its unique properties.

RWR80S16R5FRRSL resistors are designed to dissipate energy through annular slots that allow heating elements to flow through. The heat generated by the resistor is then dissipated by placing a thermally dissipative material like a ceramic or metal near the slots. This helps to keep the resistor cool and ensures that it functions properly.

Conclusion

In conclusion, RWR80S16R5FRRSL is a wirewound resistor used in the through-hole technique and fits in numerous applications that require high power but little thermal dissipation. It has an advantage over the traditional wirewound resistors because of its flame retardant coating and the availability of the slots for dissipative cooling, which makes it more efficient and stable.
