R3J2K7E Application Field and Working Principle

Through hole resistors, also known as leaded resistors, are common components used in various types of electrical and electronic circuits. They are widely used for computing, avionics, telecommunications, circuit protection and medical electronics.

A through hole resistor is a two-terminal, linear electrical component that has a fixed electrical resistance. The resistance value is marked on the resistor’s body. The resistor’s resistance can be controlled by changing its length, width, material type and thickness.

The R3J2K7E is a through hole resistor that is widely used in various electrical and electronic applications. It has a resistance value of 3kΩ, 2W power rating, and a 7mm total length. It is made of a metal film material with a tolerance of ±5%. The R3J2K7E resistor has an operating temperature range of -55°C to +155°C and a maximum voltage rating of 150V.

To understand the working principle of a through hole resistor, it’s helpful to understand how current flows when it encounters resistance. As current passes through a resistor, a fraction of the energy is turned into heat due to the resistance. As a result, the voltage across the resistor is reduced, which is equal to the product of current and resistance (R = V/I). The amount of energy dissipated is proportional to the square of the current.

The R3J2K7E through hole resistor is a general-purpose component that can be used for applications such as DC offset attenuation, impedance matching, voltage divider networks, signal conditioning and current limiting. It is an excellent choice for applications with high reliability requirements such as medical electronics and aerospace systems.

In summary, the R3J2K7E through hole resistor is a common two-terminal, linear electrical component that is widely used in various electrical and electronic applications. It has a resistance value of 3kΩ, 2W power rating, and 7mm total length. It is made of a metal film material with a tolerance of ±5%. The R3J2K7E resistor has an operating temperature range of -55°C to +155°C and a maximum voltage rating of 150V.
