ASR1JA470R

Through hole resistors are an important component of an electronic circuit as they are the most common form of electrical resistance, often used to restrict or limit electrical currents in a circuit. Such resistors can be found in a variety of applications, including the ASR1JA470R, which is a single-winding, chip-style resistor, designed for use in electrical and toy applications. The ASR1JA470R, like all through hole resistors, can be used to either limit the amount of current in the circuit or act as a voltage divider, depending on the application and design.

A through hole resistor is composed of a ceramic body with a single winding inside it. This single winding contains numerous metal webs, usually made of copper or aluminum, that run from one end of the resistor to the other and bridge the gap between the ceramic body and the winding\'s conductor. It is these metal webs that are responsible for carrying current through the resistor. The thickness of these metal webs determines how much current can flow through the resistor. The metal webs are separated by insulating material, which helps to prevent short circuiting and current leakage.

The ASR1JA470R is a chip-style, single-winding resistor, specifically designed for electrical and toy applications. It is a through hole resistor, meaning that it is constructed from a wide metallic strip that creates multiple layers of metal webs. This allows the ASR1JA470R to process a larger amount of current than conventional resistors. The metal web layers are separated by an insulating material to minimize electrical leakage, and the metal webs themselves are insulated to prevent short circuiting.

The ASR1JA470R has a standard resistance of 0.47 ohms and a tolerance of ±0.05 ohms. This means that when in use, resistors with this designation can vary in their resistance from 0.45 to 0.49 ohms. The ASR1JA470R is also rated for a maximum power dissipation of 0.2 watts, meaning that it can carry and dissipate 0.2 watts of power before burning out. While this is relatively low, this rating makes the ASR1JA470R ideal for low current applications, such as those found in toys.

In electrical and toy applications, the ASR1JA470R is commonly used to limit the amount of current or act as a voltage divider. As a current limiter, the ASR1JA470R limits the amount of current that can flow through the circuit. As a voltage divider, the resistor is used to divide the voltage in the circuit, causing one side of the circuit to be at a higher voltage than the other.

While the ASR1JA470R has a maximum power dissipation rating of 0.2 watts, the resistor can develop significant temperature in the application due to the resistance created by the single winding. Because of this, the ASR1JA470R must be placed in a well-ventilated location, and should be mounted on PCBs with plated through-holes for optimum heat dissipation.

The ASR1JA470R is an example of a through hole resistor, which is a common type of resistor used in many electrical and toy applications. It is composed of a ceramic body with a single winding, and multiple metal webs, which are separated by an insulating material. These metal webs provide resistance in the circuit and limit the amount of current or operate as a voltage divider, depending on the application. While the ASR1JA470R has a maximum power dissipation rating of 0.2 watts, it must be placed in a well-ventilated location, and should be mounted on PCBs with plated through-holes for optimal heat dissipation.
