Through Hole Resistors

Through hole resistors are the most common type of components used in electrical device designs. They are commonly made of carbon film with a plastic body and a lead frame for electrical connection.

The MP915-25.0-1% is an example of a through hole resistor. It is a three pin type resistor with dimensions of 9mm*15mm. The permissible overload power is 10W and the temperature coefficient for this type of resistor is 2450 PPM/℃.

Application Field

The MP915-25.0-1% is used to control the flow of current in electrical circuits. It is commonly used to prevent electrical over-voltage or over-current from damaging electrical components. Some typical application fields include power supplies, LED lighting, auto/motorcycle/industrial control systems, navigation systems, domestic appliances, audio/video systems, electrical instruments, and medical equipment.

Working Principle

The MP915-25.0-1% through hole resistor works by providing a fixed opposition to the flow of current. When an external current is applied, the resistor produces a proportional voltage drop, which is determined by the resistor’s fixed resistance value. This voltage drop, known as the “load voltage”, is the difference between the potential of the current source and the potential of the circuit load.

The material of the resistor determines its resistance. In the MP915-25.0-1% through hole resistor, the material is a carbon film which has a low resistance in comparison to other resistor materials. When current passes through the resistor, the temperature of the resistor increases due to Joule heating. The temperature coefficient of the MP915-25.0-1% through hole resistor is 2450 PPM/℃, which means that the resistance increases by 2450 parts-per-million (PPM) for each degree increase in temperature.

Through hole resistors are designed to withstand overloads up to a certain point before failing. The permissible overload of the MP915-25.0-1% through hole resistor is 10W. This means that the resistor can handle up to 10W of power before it is damaged.

In summary, the MP915-25.0-1% through hole resistor is used to control the flow of current in electrical circuits. It has a fixed resistance value, a temperature coefficient of 2450 PPM/℃, and a permissible overload of 10W. These characteristics make the MP915-25.0-1% ideal for applications in a wide variety of commercial and industrial applications.
