Through Hole Resistors are one of the most basic resistors used in electronic circuits and equipment. The OM2405E-R58 is an example of such a resistor, designed for applications with both fast-acting and high-temperature stability. This type of resistor is made up of several components connected together which offer protection against overload and inrush current, high accuracy, stability, and resistance to adverse environmental conditions.

Its most common application is as a Voltage Divider in an AC selective voltage regulation circuit. It is mainly used in applications such as motor control, automotive lighting, power tools, and window blinds. The OM2405E-R58 is primarily manufactured as a through-hole part, suitable for mounting on a PCB. It is encapsulated in a resin housing which is designed to offer protection against overload and inrush currents. It has a power rating of 5W and a dissipation capability of at least 5W per element, which makes it ideal for applications that require high power and stable performance.

The OM2405E-R58 works by having an output voltage proportional to the input voltage. This voltage controlling property is achieved via a negative feedback mechanism. As the input voltage rises, the output voltage also rises, but at a slower rate. The voltage gain of this type of resistor is limited to four times its rated resistance value. As the input voltage decreases, the output voltage decreases at an even slower rate with no change in resistance.

The working principle of the OM2405E-R58 is based on a discrete power semiconductor chip that is connected to two resistor networks. This chip includes a P-channel and an N-channel MOSFETs, which are connected so that one controls the output voltage and the other forms the positive feedback loop. The two networks are connected to the output terminal of the P-channel MOSFET and the negative-feedback control terminal of the N-channel MOSFET. A controller operates these two networks in order to maintain the desired output resistance over a wide range of input voltages.

The OM2405E-R58 is an ideal solution for a variety of applications and has a number of advantages over other types of discrete resistor networks. In addition to offering a high degree of accuracy, it requires minimal external components and can be implemented without complicated application-specific circuitry. It is also extremely reliable and can withstand high temperatures and overload conditions. When used as a voltage stabilizer, the OM2405E-R58 is said to be immune to main voltage fluctuations, since it only requires a very small DC supply to generate its output voltage.

The OM2405E-R58 is used extensively in applications such as temperature-sensitive devices, motor control, automotive lighting, power tools, window blinds and more. This resistor has a wide operating temperature range of -40°C to 80°C, making it suitable for use in a variety of environments. Its compact size and rugged construction make it an ideal choice for many applications.
