Through Hole Resistors

Through hole resistors refer to components that are placed in an appropriate location on a circuit board and secured by fastening it between the board and some other surface, such as the chassis of the device. This type of resistor is intended for use in higher power applications, such as equipment that requires high voltage and current levels. Definition: The term RNMF12FTC3R90 refers to a through-hole resistor with a maximum power rating of 12 Watts and a resistance value of 3.9 Ohms.

Application Field

RNMF12FTC3R90 through-hole resistors are typically used in applications that require devices of higher power, such as medical electronics, commercial and industrial equipment, military and aerospace equipment, automotive, transport and power industries. The device can also be found in areas where high temperature, overloads and vibrations are expected, such as switchgear, transformers, circuit breakers and fuse boxes.

Working Principle

RNMF12FTC3R90 through-hole resistors are engineered to resist the flow of electric current while dissipating heat in the process. They operate on the principle of Ohm’s law, which states that the voltage applied across a resistor is equal to the magnitude of current flowing through it multiplied by the resistance of the resistor between two points. The device dissipates the energy as heat energy and as the current flows through the resistor, the device gets hot. Thus, the device functions as a heat sink for the circuit.

When dealing with higher power applications, the use of a through-hole resistor is essential as it allows a larger contact area for the power to flow. The device also offers a higher degree of design flexibility when compared to surface mount counterparts. Furthermore, as opposed to smaller surface mount resistors, the through-hole resistors are clamped into place which prevents them from being pulled loose during testing and use.

In conclusion, RNMF12FTC3R90 through-hole resistors are essential components used in higher power applications due to their larger contact area and design flexibility. They are also secured into the board with an appropriate force which helps prevent accidental loosening due to vibration or other factors.
