Through Hole Resistors

Through hole resistors are an electronic component which is used to resist the flow of current within an electric circuit. It is designed to be connected to a printed circuit board (PCB) via its leads which pass through holes in the circuit board. The leads are typically soldered to the PCB, allowing electrical contact between the component and the board. The PWR220T-20-1001F is an example of a through hole resistor.

PWR220T-20-1001F Application Field

The PWR220T-20-1001F through hole resistor is a surface mount or vertical mount component used in applications where electrical insulation is required from the base material of a printed circuit board. It is useful in applications such as:

• Board level EMI/RFI protection
• High-frequency signal Interface
• High performance power systems
• Ground loops/floating grounds

The PWR220T-20-1001F has an extended temperature range of -55 to +105 degC and can operate in a voltage range of 1 to 250 volts. This makes it an ideal component for a range of applications where a reliable, high-performance resistor is required.

PWR220T-20-1001F Working Principle

The PWR220T-20-1001F is a through hole resistor which works by using the Joule effect. This effect states that an electrical current will be dissipated as heat when an electrical potential is applied across a conductor. The PWR220T-20-1001F works by using this effect to increase the temperature of the resistor, which in turn decreases its resistance. This decrease in resistance allows a small amount of current to pass through the resistor, thereby dissipating the large amount of heat generated by the passage of the electrical current.

This resistor is able to handle large amounts of current, making it ideal for applications such as protection against overloads and voltage spikes. As the resistor heats up, its resistance is reduced, allowing for increased current to pass through it. As the current dissipates the heat generated is spread throughout the resistor, preventing any hotspots or potential malfunctions.

Conclusion

The PWR220T-20-1001F is an example of a through hole resistor which can be used in a range of applications. It uses the Joule effect to decrease its resistance, allowing for an increased current to flow through it, while also dissipating any heat generated by the passage of the current. This makes it an ideal component for applications where electrical insulation is required, as well as being able to handle large amounts of current.
