Through Hole Resistors, such as the SQP25AJB-3K, are designed to resist the flow of electric current in various applications. They are used to limit the amount of current that passes through a circuit, as well as to provide corrective feedback in control systems to stabilize the output voltage. Commonly found in power supplies, amplifiers, motor drives, and consumer electronics, these resistors typically feature a cylindrical body with a threaded lead at one end, allowing registration into predefined holes on the PCB.

The SQP25AJB-3K is a through-hole mount resistor with a flat plate construction offering excellent heat transfer, designed for printed circuit boards. It is sold in individual quantities and has a power rating of 2.5W. This resistor has a maximum resistance of 10Kω and is offered in standard 5% tolerance. It is capable of operating at temperatures up to 175°C and offers good stability and insulation against environmental factors such as humidity, temperature, and vibration due to its encapsulated construction. It is also UL94V-0 approved for fire safety.

The SQP25AJB-3K\'s working principle is based on the electrical resistance of the resistor material. When a voltage is applied to the resistor, a proportional amount of current will flow through it. The amount of current is determined by the resistor\'s resistance value. Since resistors are made of an impedance material, the current flow is limited and the voltage is divided accordingly. The resistor\'s value can be changed by adjusting the length and width of the resistor body, as well as by the addition or removal of various material components.

The SQP25AJB-3K has various applications due to its broad range of tolerance and temperature ratings. It is suitable for use in a variety of applications such as: automotive, power-supply, amplifier, power amplifier, servo motor driver, light dimmer, consumer electronics, and other electronic devices that need precise current and voltage regulation. It can be used in the power supply section of various electronic devices and is often used in power amplifiers as a feedback element to regulate the output voltage. It can also be used in lights dimmers to ensure that the output voltage is correctly regulated.

The SQP25AJB-3K is an ideal through hole resistor for a wide range of power supply and amplifier applications. Its highly durable and reliable construction, along with its excellent temperature and tolerance ratings make it an ideal choice for any project. With its UL94 rated fire safety, it provides extra protection in the event of a fire. Furthermore, its electrical properties guarantee precise current and voltage regulation, essential in a variety of applications.
