Through Hole Resistors: W21-3R3JI Application Field and Working Principle
A through-hole resistor (THR) is an electrical resistance component that features two or more electrical terminals or contacts and is embedded in a printed circuit board (PCB). This type of resistor is characterized by its size and the number of pins that it has. The most commonly used THR resistor is called the W21-3R3JI.
The W21-3R3JI THR resistor is a three-pin, three-pole type of resistor that has a nominal power rating of 1 watt and a tolerance range of plus-or-minus 3%. The body of the resistor is constructed from a phenolic material and it includes two terminal pins and a dimensional mounting tab to make installation easier. The resistor also features a self-contained heat-sink design to dissipate heat efficiently. The resistor also has an integral flame-retardant coating to help ensure that it is very reliable and safe for use in applications where there is a high risk of fire.
The W21-3R3JI THR resistor is mainly used in consumer electronics, automotive, telecom, industrial control, computer and medical equipment applications. It can be used to create electrical resistance between two signals on an electronic circuit board. It is designed in such a way that it will offer reliable and consistent performance, as well as excellent temperature stability. Due to its small size, the resistor also has a wide working temperature range and can be used in a variety of environments without any problems.
The working principle of a THR resistor is quite simple. When a voltage is applied across its two pins, the resistor will oppose the flow of current on the circuit, thus providing a resistance to the circuit. The amount of resistance will depend on the size and construction of the resistor, as well as its internal resistance value. These types of resistors also have the ability to dissipate heat efficiently and maintain a consistent temperature profile over time. This helps ensure that the resistor will function properly and provide the desired amount of resistance.
Overall, the W21-3R3JI resistors are ideal for use in a variety of applications due to its small form factor, reliable performance, and excellent heat dissipation ability. The resistor also has a wide working temperature range which makes it ideal for use in harsh conditions. Furthermore, the resistor is very reliable and safe, due to its integral flame-retardant coating. All of these features make the W21-3R3JI THR resistor an ideal choice for a variety of applications.
