Through Hole Resistors, also commonly referred to as axial lead resistors have been in regular use for decades, and still today have many applications. This paper will focus on one model in particular, the MFP50SBBE52-1K62, discussing both its application field and working principle.

The MFP50SBBE52-1K62 is a high wattage, precision, axial lead resistor. It is primarily used in power applications to dissipate heat and control voltage on high power, high frequency circuits. The resistor dissipates energy at a rate of up to 2 Watts, making it suitable for both high and low power applications. The main advantages include its low cost, highly accurate temperature coefficient, and high capacity for dissipating heat without creating interference. Additionally, its wide operating temperature range, from -40°C to +125°C, makes it suitable for both indoor and outdoor applications.

The construction of the MFP50SBBE52-1K62 includes a base, resistive film layer, and a protective insulation layer. These three layers are then placed in a metal casing and encapsulated. The resistor consists of two electrodes that are held in place by two pieces of metal that form a bridge and allow current to flow across without actually touching the resistive material. The resistive material is typically made of nickel-chromium or other nickel alloys, while the insulation layer is usually a permeable plastic.

The working principle of the MFP50SBBE52-1K62 is relatively simple. When a current is applied to the resistor, electrical energy is lost in the form of heat and the resistor is dissipated. This loss of electrical energy is a resistance to the current flow and is measured in Ohms. As the resistor heats up, the resistance increases and eventually reaches the point where the current flow is stopped. The resistor continues to absorb heat until its temperature is equal to the surroundings, after which the resistance again decreases and the current flow resumes.

The MFP50SBBE52-1K62 is a reliable, cost-effective resistor for high-powered, high-frequency applications. Its construction and function provide many advantages including a wide operating temperature range, accurate temperature coefficient, and high capacity for dissipating heat without creating interference. It is a popular choice for many designers and engineers who require precise and consistent operation in their projects.
