Through Hole Resistors

A through hole resistor, such as the MBB02070C2374FC100, is a type of resistor designed to be through-hole mounted on a circuit board. It is used to limit the amount of current that passes through a circuit by introducing resistance to the flow of electrons. Through hole resistors are designed to be relatively low cost, reliable, and of a standardized size and form suitable for through-hole mounting on a printed circuit board (PCB).

Application Field

MBB02070C2374FC100 through hole resistors are commonly used in a wide range of electronics applications, including audio amplifiers, audio mixers, and control systems. They are also used as power-up resistors, noise mitigation resistors, device control resistors, and for impedance matching. Through hole resistors are also used to measure voltage, current, and other parameters in control systems, medical diagnostic systems, circuit protection systems, and test and measurement equipment.

Working Principle

Through hole resistors work on the principle of making the flow of electricity more difficult. They create an opposition to the current flowing in a circuit. This opposition is a physical phenomenon known as resistance. With a constant load, the voltage drop across the resistor is directly proportional to the current flowing through it. This is known as Ohm’s law and is expressed as V=IR (where V is voltage, I is current, and R is resistance). The resistance of a through hole resistor can be changed by either adding or removing a turn or winding of its conductive material. By increasing the winding of the conductor, the total resistance of the resistor increases and the current flow is reduced.

The major advantage of through hole resistors is their high level of reliability. The through-hole mounting procedure solders the component firmly to the board, ensuring no loose connections which could lead to instability or malfunction. Additionally, through hole resistors are easier to test and replace than surface mount resistors, making them ideal for applications in which maintenance or repair is likely to be necessary.
