Through Hole Resistors come in a wide variety of styles and tailored for different application fields, of which, the MMG3JT100M is a common resistor used in circuits. It has several key features, including an operating range from -55°C to +155°C, tolerance rating of ±1% and temperature coefficient of +400ppm/°C.

The MMG3JT100M, like many resistors, has a simple construction. It consists of a metal resistor element and two leads, which protrude from either side of the cylindrical body. The resistance value can be determined by measuring the length of the resistor element, as well as the width and thickness of the element itself. This is stamped on the side of the resistor element and is expressed in Ohms (Ω). The size of the lead wire can also play a large role in the unit’s overall resistance value; thicker lead wires carry more current and may, consequently, require greater resistance.

It is important to note that filaments of resistors, such as the MMG3JT100M, protrude beyond the diameter of the metal resistor element. Since these filaments are much more prone to damage than the element itself, they must be well-protected from shocks and vibration. In most cases, this is done by encasing the element and lead wires in a protective coating of either varnish or paint. Additionally, the leads can be further protected with a metallic sleeve or a braid of insulation.

The working principle behind this resistor is Ohm’s law, which states that the current through a conductor is directly proportional to the voltage applied across it. Consequently, the MMG3JT100M, as with all other resistors, restricts the flow of current through it. The magnitude of the resistance is determined by the length, width and thickness of the element, as well as the material it is formed of. In this particular unit, a high purity metal-film is used, which aids in its overall accuracy.

In summary, the MMG3JT100M through hole resistor is a common component used for providing precise and consistent resistance values over a wide range of temperatures. As with all other resistors, it functions by restricting the flow of current regulated by Ohm’s law. Its construction includes two lead wires extending from either side of a cylindrical metal resistor element, with its specific resistance value determined by measuring the length, width and thickness of the element.
