Through Hole Resistors

B12J25R application field and working principle

A Through Hole Resistor (TH Resistor) is a type of electrical resistor with two wire leads that protrudes from the side of the resistor body. The TH Resistor is a general electrical component, which can be used in a variety of different applications when electrical current is present. The primary purpose of a TH Resistor is to regulate, or reduce, current as it passes from a power source to a load. The TH Resistor also aids in creating electrical impedance and absorption of electromagnetic radiation.

Some of the most common applications of a TH Resistor include regulating the current in a circuit when connecting to multiple components, protection against surges in current, signal attenuation, impedance control, and damping of fluctuations in a circuit. Commonly, through hole resistors used in consumer electronics such as ringers, radios, amplifiers, video game consoles, and portable music players.

When it comes to TH Resistors of the B12J25R series, these specific resistors are designed with superior performance features that offer superior operational reliability and consistent performance. These resistors feature a thin metal clad construction, which resists corrosion and ensures a long service life. B12J25R resistors have a maximum voltage rating of 2V and a maximum power rating of 100MW.

The working principle of a TH Resistor in general is relatively straightforward. When an electrical current passes through the resistors, a portion of the energy is converted into heat. This energy is dissipated from the resistor, thereby reducing the voltage or amperage and decreasing the flow of current. Every resistor will reduce the current in the same proportion when the same electrical potential is applied to them.
