Through-hole resistors, also known as leaded resistors, are resistors used with components that require a physical connection through a circuit board or solder joint. The RWR82S1150FRBSL is a generic through-hole resistor from the RWR series. It features high power ratings, high surge capability, and low ohmic resistance values.

RWR82S1150FRBSL Application Fields and Working Principle

The RWR82S1150FRBSL is a suitable through-hole resistor for use in power applications such as medium and high voltage power supplies, large-scale power distribution, and industrial control system components. The RWR82S1150FRBSL features high-power ratings and high surge capability. The RWR82S1150FRBSL has a maximum power dissipation of 1.5 watts (W), a maximum voltage rating of 600 volts (V), and a rated power dissipation of 0.15 watt (W). It is composed of a carbon-based dielectric and a wrap-around wirewound construction, and it is rated to operate in temperatures up to 105°C.

The RWR82S1150FRBSL through-hole resistor has an ohmic resistance value that is controlled by varying the width of the carbon-based dielectric. The carbon-based material works to reduce the number of thermally active electrons in the resistor, which in turn helps to maintain a consistent ohmic resistance value even at high temperatures. As electricity passes through the resistor, the electrons from the dielectric create resistance to the flow of electrical current, which then creates heat. The resistance of the resistor is measured in ohms (Ω) and is marked on the resistor body.

The wrap-around wirewound construction also helps to maintain its consistency in high temperatures. It is made from very thin wires that are wound in a helical pattern around the carbon-based dielectric. This design helps to increase the surface area of the wire, which gives it a better thermal dissipation ability. The wrap-around wirewound construction also increases the tolerance and accuracy of the RWR82S1150FRBSL through-hole resistor. It has a resistance tolerance of ±1%, which is higher than other through-hole resistors, and it is rated to have a maximum inaccuracy of 0.1%.

The RWR82S1150FRBSL through-hole resistor also has improved surge capability. It is rated to have a peak surge current rating of 1,250 amps (A), which is higher than most other through-hole resistors. This allows it to handle more power than other components in a circuit, which makes it a suitable choice for applications such as motor drives, power supplies, and other high-power components.

In conclusion, the RWR82S1150FRBSL through-hole resistor is a suitable choice for power applications, such as medium and high voltage power supplies, large-scale power distribution, and industrial control system components. It has a high power rating which allows it to contact more current than other resistors in the same wattage range, a high surge capability which allows it to handle more power than other components in a circuit, and a very accurate and consistent ohmic resistance value which is maintained even at high temperatures.
