Through Hole Resistors

Through hole resistors are a type of electronic components composed of resistive elements, components, and other materials. In terms of electrical performance, through hole resistors can be divided into two voltage levels: high and low. High voltage level resistors usually use metal oxide film, varistors, non-inductive resistors and other materials, while the low voltage level resistors usually use metal film, carbon film, fusible resistor and other materials.

ALSR057K000JE12 application field and working principle

ALSR057K000JE12 is a type of low voltage metal film through hole resistor, which is widely used in communication, medical, security, industrial control, electronic and other industries. The characteristic of this type of resistors is the low temperature coefficient, small size and light weight.

The ALSR057K000JE12 is a two-terminal through hole resistor with metal film as resistance material. Its structure is composed of two long and thin metal-film strips intercrossed and pressed together. The resistance value of the resistor is determined by the length, width, and area of the strips as well as the thickness and composition of the metal-film. In addition, the resistor also has an internal magnetic shield to prevent the influence of external inductor.

Working principle is basic. When the electric current passes through the metal-film strips of the resistor, the strip will contract and generate heat due to Joule\'s heat. The heat generated by the strip will be quickly dissipated to the surrounding environment through convection and radiation. At the same time, eddies will be generated in the resistor to induce a voltage shift. This voltage shift will produce additional current and pressure drop, thus increasing the power loss. Thus, the current gradually decreases after passing through the ALSR057K000JE12, and finally the desired voltage and electric current values are obtained.

The advantage of through hole resistors compared with surface mount resistors is its strong environment adaptability. Through hole resistors can ensure the stability of electric current output in harsh environment conditions such as high temperature, moisture and vibration. At the same time, through hole resistors have high reliability, good durability and strong resistance to aging. It can completely meet the needs of the application field.

Overall, the ALSR057K000JE12 is an excellent choice for both industrial and professional settings. Its low temperature coefficient, small size, light weight, and high reliability are ideal for applications where precise voltage and current outputs are needed. It is also a great choice for use in harsh environment conditions such as high temperature, moisture and vibration, as it offers strong environment adaptability.
