Through Hole Resistors: ALSR10400R0FE12 Application Field and Working PrincipleThrough hole resistors are electrical components consisting of elements made from metal, metal alloy, alloys and oxide ceramics. Through hole resistors are divided into two types according to their structure: Axial and Radial. The ALSR10400R0FE12 is an axial type through hole resistor. The electrical property of resistance is simply the ratio of potential difference or voltage applied across two points in the electrical circuit, with a defined current flowing in the same direction between these two points. The electrical resistance of a resistor is measured in ohms or Ω symbol. The ALSR10400R0FE12 is a fixed wirewound axial lead resistor with a rated power of 10W, a resistance value of 400Ω, and a tolerance value of ±12%. It uses a ceramic core coated with wire. The core is constructed of insulating material on which is wound a metal wire. The ALSR10400R0FE12 is a high-temperature, high reliable through hole resistor suitable for a variety of applications such as: audio equipment, amplifier, transformer or AC/DC balance amplifier etc., and is widely used in electric control panels, such as in Automotive and HVAC controls. Heating is the major factor influencing the life of ALSR10400R0FE12. Just like other resistors, the ALRS10400R0FE12 dissipates power as heat when current passes through it. The magnitude of current determines the heating effect. The more current passes through the resistor, the more heat it dissipates. The allowable temperature rise of the resistor must remain below a given value to ensure the resistor does not fail due to excessive heating. The working principle of ALSR10400R0FE12 follows Ohm’s Law stating that the current passing through a conductor is directly proportional to the voltage across the conductor. The current passes through a resistor will cause a voltage drop across the resistor proportional to its resistance, and current flow will be limited in accordance with Ohms law. ALSR10400R0FE12 is a through hole resistor with a high resistance. This type of through hole resistor can be used in various areas, such as in industrial and automotive control panels, as well as in electronic and electrical products. The resistor has a ceramic core with a metal wire wrapped around it. It is designed to handle high power and high temperatures with low-tolerance range of ±12%. ALSR10400R0FE12 follows the Principles of Ohms Law and can be used in wide range of applications.
