Through hole resistors refer to a type of passive electronic component, more commonly known as resistors. They are used to reduce the current flow and control the voltage levels in circuits. The UB3C-5RF1 is a through hole resistor with a symmetrical punch-out construction and high tolerance for environmental conditions, making it suitable for a wide variety of applications. This article will explain the application field and working principle of the UB3C-5RF1 through hole resistor.

Applications Field

The UB3C-5RF1 is a through hole resistor of very high stability and accuracy. It is ideal for use in applications that require low voltages and high currents, such as amplifiers, audio and video equipment, and switch mode power supplies (SMPS). Additionally, the UB3C-5RF1 is well suited for use in test and measurement instruments and automotive applications due to its high tolerance for harsh conditions. The UB3C-5RF1 is available in a variety of package sizes, making it suitable for a variety of applications.

Working Principle

The UB3C-5RF1 is a through hole resistor with a symmetrical punch-out construction. This construction design allows the resistor to operate with a wider range of environmental conditions, such as high temperatures, high humidity, and high vibrations. As the current passes through the UB3C-5RF1, the element inside it will change its resistance according to the current flow. This change in resistance is known as resistance drift and it limits the accuracy of the device. To mitigate this, the UB3C-5RF1 is designed with a built-in temperature coefficient of resistance (TCR) to maintain accuracy over time.

The UB3C-5RF1 is constructed with three layers of material and a epoxy finish to ensure the device will not be adversely affected by external conditions. The first layer is a thin-film resistive material which is deposited on a ceramic substrate, which provides good heat transfer and insulation. The second layer is an anodised aluminium housing which provides protection from EMI (electromagnetic interference) and Corrosive gases. The third layer is a solderable epoxy finish which provides the mechanical structure of the device and provides a low-resistance connection to the circuit.

To summarise, the UB3C-5RF1 is a high-stability and accuracy through hole resistor. It is well suited for use in low voltage, high current applications and offers good performance in harsh environments. It is also available in a wide variety of sizes, making it suitable for most applications.
