Through Hole Resistors vary in many applications, from power or motion control to current limiting in circuits. This article will focus on the RR03J200KTB resistors as an example for the types of resistors in the through hole category.

The RR03J200KTB is a through hole-type resistor with a power rating of up to 25 Watts and a current rating of up to 3A. Its resistance value is 200KΩ ± 5%. The resistor has an operating temperature range of -55℃ to +150℃, and features a cylindrical style body made of ceramic with a lead-frame contact material.

The resistor is very popular due to its well-known stability and reliability. This type of resistor has many benefits, such as an outstanding temperature coefficient of resistance (TCR) of better than ±100 ppm/℃, tremendous power dissipation capability, high durability, excellent dimensional stability and thermal shock resistance, and a low thermal EMF. The robust resistors are also RoHS compliant.

The RR03J200KTB is used in a wide range of applications. These include LED drivers, motor controllers, dc/ac converters, power supplies, automotive electronics, temperature control systems, security systems, home audio systems, and test and measurement equipment.

The working principle of the RR03J200KTB is based on electricity passing through materials such as metal or semi-conducting material such as resistive ceramics. In the presence of a voltage, the material will oppose the flow of current by due to its resistance, a property called Ohm\'s law. It states that the amount of current that passes through a resistor is directly proportional to the voltage across the resistor.

Firstly, during the working process, when an external voltage is placed across the resistor, current will begin to flow through the resistive body. This induced current will cause the resistor to heat up, and this heat will be dissipated through heat transfer by convection or dissipated through deterioration of the device.

Due to temperature variations in the environment, the resistor\'s resistance changes. The rate of that change can be dependent on the type of resistor material, the capacitor type, the size of the resistor, and the resistor\'s power rating. The magnitude of its operating temperature range and the environmental influences on the resistor are factors that affect its performance. In addition, application-specific considerations such as lead span, lead depth, and other features allow you to better customize the resistors for your specific needs.

The RR03J200KTB is an integral part of many circuits, and its features make it an excellent choice for a variety of applications. It is resistant to thermal shock, has a low thermal EMF, and outstanding temperature stability. Its operating temperature range and environmental influences on the resistor make it suitable for numerous demanding applications. The resistor also offers strong mechanical reliability and dimensional stability.
