Through Hole Resistors are among the simplest components used in electrical circuits - but they can also be very effective. The RWR78S5110FRB12 is one such component, a resin-coated fixed-value resistor that is particularly suitable for high-temperature applications.

This type of Through Hole Resistor was specifically designed to provide precise current limiting in power supply circuits as well as protection from unwanted harmonic components. It is suitable for many applications, including high-voltage circuits, automotive applications, and industrial process control.

The RWR78S5110FRB12 has a wide operating temperature range, allowing it to perform reliably in hot environments. It is also very flexible in terms of value selection, and is available in a range of tolerances from ±50ppm to ±100ppm.

It can handle a maximum overload of 40 watts and is designed to be highly durable. It also offers excellent protection against surges, which makes it a great choice for high-voltage applications. The ceramic body also helps to keep the unit cool to ensure long-term reliability.

The RWR78S5110FRB12 is constructed with a metal film element that has been compressed in a oil-filled structure. The body is made of a durable ceramic, and heat-resistant internal components are installed to ensure quality temperatue performance. The resistor is capable of withstanding temperatures up to +135°C.

The working principle of the RWR78S5110FRB12 is simple – it works by limiting the current flow through the resistor element. The resistor itself functions as a bridge between the "source" and the "load" side of the circuit, and as the current flow through the resistor increases, the voltage drop across it also increases.

This increase in voltage then forces the current to flow at the maximum allowed level, and it is this action that limits the overall current flow. This means that no matter what current is applied to the resistor, it will always keep the voltage at the same level, ensuring consistent and reliable power delivery.

The RWR78S5110FRB12 is an ideal choice for many applications, especially those in hot environments or ones requiring high precision. It is durable, reliable and easy to use, and its wide temperature range makes it suitable for most applications.
