Through Hole Resistors: CS3FR003E application field and working principle

Through-hole resistors are electrical components that are used to reduce electrical current. By adding a resistance into a circuit, the current will be reduced but the voltage will remain unchanged. This is extremely useful in controlling the amount of electrical current flowing through a circuit.

CS3FR003E is a type of through-hole resistor made by ZMD. It’s primarily used for short-delay or emergency stop circuit solutions. It can delay the turn-off signal, providing a safety margin for users to switch quickly with emergency stop in case of emergency.

The Internal Structure and Working Principle of CS3FR003E

The inner structure of a CS3FR003E is composed of a ceramic body package with a pair of contacts on the lead frame. The ceramic body is an insulator, designed to isolate the lead frame from the resistor element. The resistor element is over-molded into a plastic sleeve in the ceramic body.

The CS3FR003E has a resistive element, which is usually a carbon-film. When the current flows through the resistor, it captures some energy, which results in a voltage/current ratio. This is the voltage/current ratio that is determined by the resistor\'s resistance value. The voltage drop across the resistor is measured with a multimeter, and it is used to help calculate the resistor\'s resistance. Generally, the lower the resistance value of the resistor, the lower the voltage drop across it.

The Characteristics and Advantages of CS3FR003E

The CS3FR003E has a number of advantages that make it an excellent choice for emergency stop or short-delay circuit solutions. It has a high temperature coefficient, which means it can handle high temperatures without compromising its effectiveness. It also has a good thermal stability, meaning it can maintain its resistance value over time, no matter how high the temperature gets.
