Through Hole Resistors (THR) are widely used in the electronics industry. The RWR71S4701FSB12 is a THR type device, which has a unique application field and working principle.
The RWR71S4701FSB12 is a high-precision THR device specifically designed for power applications. It is capable of handling up to 3.3 Amps of current with minimal power dissipation and can be used in high temperature environments without any heatsinking. The device has a resistance range of 1Ω to 1MΩ, making it suitable for a wide variety of applications.
The working principle of the RWR71S4701FSB12 is based on the Joule-Thomson effect. This effect involves the physical conversion of electrical energy into heat energy localized to the resistor element. This conversion takes place when current passes through the resistor and is converted into thermal energy. The resistance value of the resistor is determined by the amount of current that is allowed to pass through the resistor element.
The main application field for the RWR71S4701FSB12 is in the power supply and computer industry. This device can be used to convert AC voltage into DC voltage in power supplies, to regulate current flow in DC motors and for voltage regulation in computer circuits. It is also ideal for use with high power transistors and for voltage drop compensation.
The RWR71S4701FSB12 has a number of advantages over other THR devices. It is highly stable and accurate, with a temperature coefficient of ±0.05%/°C. The device also has excellent moisture and corrosion resistance, making it suitable for use in adverse environmental conditions. In addition, the device has a low power dissipation of less than 0.25W, making it suitable for applications where power savings are critical.
The RWR71S4701FSB12 is a versatile THR device that is suitable for a variety of applications. Its unique features make it a reliable and cost-effective solution for power supply and computer components. The device is capable of high precision and can be used in high temperature environments without any need for heatsinking. It is highly stable and accurate with a temperature coefficient of ±0.05%/°C and has excellent moisture and corrosion resistance. This makes it an ideal choice for power supply and computer components, where power savings and reliability are key considerations.
