The RNC55J1872BPRSL is further suitable for applications where isolation and reliability is important. A typical feature of a through-hole resistor is its high isolation, meaning it is well-insulated from adjacent components, improving the circuit’s overall performance. The resistor features a high maximum voltage rating of 350V, meaning it can function in high-voltage systems such as power distribution or generator control systems.

Working Principle

The working principle of the RNC55J1872BPRSL can be simply explained in a two-step process. First, when a voltage is applied across the resistor, the electrons flow through the resistor, creating a current. As current passes through the resistor, a resistance is created, in turn producing heat due to the Ohm’s Law. This heat is dissipated through the leads of the resistor. Second, the resistor acts to limit the current through the circuit by providing a resistance. This limits the amount of energy dissipated by the circuit, providing improved reliability and overall circuit performance.

Furthermore, the RNC55J1872BPRSL provides improved resistance accuracy and temperature coefficient due to its reliable construction. This is achieved due to the resistor’s low temperature coefficient and tight tolerance, which improves the overall circuit performance. The resistor features an isolation voltage of 300V, providing insulation from surrounding voltage sources.
