CA00021K000JB12

Through Hole Resistors, like CA00021K000JB12, are widely used in many electronic and electrical devices. These resistors are utilised in a range of applications, depending on the design specification of the component. It is important to consider the working principle behind the component to understand how and why it is used in a particular application

A through-hole resistor is one that is soldered directly to the printed circuit board (PCB). This type of resistor is constructed in two distinct parts; a cylindrical body and a flat bottom. The cylindrical body is usually constructed from ceramic material, while the flat bottom is usually a conductive metal. The resistor is hollow and has several terminals at the top of the body in which the wires of the circuit can be connected. The body of the resistor contains a metal strip that is etched with holes, which are filled with the resistive material. This material is connected to both terminals at the top.

In operation, an electric current is applied to the resistor, which then restricts the flow of current in the circuit. The resistance offered by the resistor can be altered in some designs by using a variable resistor, a type of potentiometer. This is adjusted by changing the resistance of the resistor using a knob or a dial to alter the resistance of the resistor.

Through Hole Resistors, like CA00021K000JB12, are commonly used in both AC and DC circuits. These resistors are used in various electrical applications such as power supplies, voltage reference circuits, signal processing circuits, radio frequency circuits, automotive applications, and communications circuits. They are also used in a variety of consumer products, including computers, mobile phones, gaming devices, electronic toys, and appliances.

One of the main advantages of Through Hole Resistors is their size. They are much smaller and lighter than their surface mount equivalents, making them ideal for applications that require space and weight to be kept to a minimum. This type of resistor is also relatively cheap and easy to manufacture, making them a popular choice for many applications.

In short, Through Hole Resistors, like CA00021K000JB12, are used in many electronic and electrical devices as they are small, lightweight, and relatively cheap. Their simple construction makes them easy to manufacture and they are suited to both AC and DC circuits.
