Introduction

The ALSR032K200FE12 is a through hole resistor used mostly in the circuit board assembly of various electronic devices. This high-performance resistor is a popular choice for its wide range of power supply applications in the consumer electronic market.

Application Field and Working Principle

The ALSR032K200FE12 through hole resistor is a resistive element made of corrugated metal film for resistors. It is a one-piece construction and consists of two thick-film layers, printed onto an insulating base substrate with an electrically conductive attachment wire. The resistor is used in the circuit board assembly of electric and electronic devices, providing them with a reliable, cost-effective heating element.The working principle of the ALSR032K200FE12 through hole resistor is based on the electrical resistance of the metal film. The metal film has a certain resistance, which is reduced as the current passes through it. This resistance is dependent on both the material of the metal film and the thickness of the layer. Resistance is also affected by the number of metal layers. As different electrical signals are passed through the metal layer, resistance changes, resulting in a change in current flow.The ALSR032K200FE12 through hole resistor is constructed with two thick-film layers. The inner layer consists of a ceramic substrate with an electrically conductive attachment wire on one side. An electrical current is passed through the conductive attachment wire, and resistance is generated in the metal film layer between it and the inner layer.The outer layer of the ALSR032K200FE12 through hole resistor is a layer of insulating material. It helps to reduce electrical losses, protecting the inner layer from corrosion and short-circuits. It also helps to increase the efficiency of the resistor by preventing heat loss.

Advantages

Using the ALSR032K200FE12 through hole resistor has several advantages. It is a reliable and cost-effective heating element with a wide temperature range. The resistor also provides high power ratings and low current losses. Because of its two-layer construction, the ALSR032K200FE12 has high electrical insulation and strong mechanical properties. Additionally, its through hole design allows for easy installation in circuit boards.

Conclusion

The ALSR032K200FE12 through hole resistor is a high-performance resistor used in the circuit board assembly of electric and electronic devices. The resistor works by generating resistance in the metal film between the inner and outer layers, resulting in a change in current flow. With its reliable, cost-effective heating element, high power ratings, low current losses, and easy installation capabilities, the ALSR032K200FE12 through hole resistor is an ideal choice for any power supply applications.
