Through Hole Resistors

Through hole resistors refer to passive electrical components, which can resist or lower the current flowing through them and stabilize the circuit. They are used to protect circuits or maintain the signal level of the circuits. The resistance levels of through hole resistors can be as small as tens of nano-ohms and as great as megohms. One example is RNC60H2261DSRSL.

RNC60H2261DSRSL Application Field and Working Principle

RNC60H2261DSRSL is a type of PTC through hole resistor. RNC60H2261DSRSL belongs to self-restoring resistor. It has a simple structure composed of resistive element, PC housing and two printed pins. It can serve as the major component of limit switch, circuit protection, circuit control, intelligent control circuit, automobile electrical appliance, instrumentation, small current and voltage attenuation.RNC60H2261DSRSL uses two conductors to form two contact points and establish an electric resistance. The resistance element generally consists of carbon film materials, resistive elements, ceramic materials and noble metal. When the current through RNC60H2261DSRSL reaches the rated operating current tolerance, the resistor’s temperature increases rapidly. PTC materials has a large temperature coefficient. The increasing temperature causes the resistance to increase exponentially, and eventually, the current will drop sharply, protect the components, and breakge the circuit.

RNC60H2261DSRSL Features

RNC60H2261DSRSL has its own advantages:

• Small size and light weight, easy to install and hardly deformed
• High insulation resistance, good electrical performance, and high accuracy.
• Large overload capacity, durable and stable performance
• High withstand voltage, flame retardant and UL94-V2 certified
