Through Hole Resistors are a type of resistor that is mounted from the outside of a circuit board, in contrast to surface mount components which are soldered onto the surface of the board. Through Hole Resistors are used to limit the flow of current in an electronic circuit, and come in a variety of shapes and sizes. The 25J20K Application Field and Working Principle is one such type of Through Hole Resistor.

The 25J20K is a through-hole type resistor manufactured by the Japanese company Ohmite. It is a cylindrical, ceramic resistor that features an integral mounting flange to secure it to a PCB. The end caps are secured to the resistor body via two countersunk screws, and the terminals are soldered to the PCB prior to mounting. It has a maximum power rating of 400 watts, a maximum voltage rating of 1000 volts, and a maximum current rating of 20 amps. It is suitable for applications such as high power resistor networks, high voltage circuits, motor control coils, power supplies, and so on.

The working principle of the 25J20K is based on Ohmite’s long-standing “Ohmic Drop” technology. This technology works by creating a resistance between the resistor’s leads. When current flows through the resistor, the resistance causes it to “drop” from the voltage applied to it. The amount of voltage drop is proportional to the amount of current flowing through the resistor. The amount of current that flows determines the amount of voltage that is “dropped” by the resistor. This is known as the “Ohmic drop”.

The 25J20K can be used in a variety of applications including static and dynamic matching circuits, signal conditioning, wave shaping, and so on. It is capable of withstanding high power applications and is suitable for temperatures up to +125 degrees Celsius. It is UL Certified and CSA Recognized components, making it suitable for commercial and industrial use.

In summary, the 25J20K is a through hole resistor manufactured by Ohmite. It has a maximum power rating of 400 watts, a maximum voltage rating of 1000 volts, and a maximum current rating of 20 amps. It is suitable for applications such as high power resistor networks, high voltage circuits, motor control coils, power supplies and so on. Its working principle is based on the “Ohmic drop” technology which works by creating a resistance between the resistor’s leads. It is capable of withstanding high power applications and is suitable for temperatures up to +125 degrees Celsius. The 25J20K is UL Certified and CSA Recognized, making it suitable for commercial and industrial use.
