Introduction to Through Hole Resistors

Through hole resistors are a type of resistor that carries electrical current and helps maintain the flow or resistance within a circuit. Depending on the material used and the resistor’s construction, through hole resistors can be used for a variety of applications.

Resistor Types

Through hole resistors come in a variety of materials, shapes, and sizes. A few common types are:

• Carbon composition resistors. Typically composed of a mixture of carbon and rubber, and are mostly used for low-current, low-resistance applications.
• Carbon film resistors. Made from thin layers of carbon film and are used for both high- and low-current applications.
• Wire wound resistors. Made of wire wound around a cylindrical element and used for high-voltage, high-current applications.
• Metal oxide resistors. Composed of metal oxide and typically used for high-current, low-resistance applications.
• Ceramic-encapsulated resistors. Sealed in a ceramic body that can withstand high heat and used for high-voltage and high-current applications.

SQZ15AJB-4K7 Application Field and Working Principle

The SQZ15AJB-4K7 is a through hole resistor. It is a ceramic-encapsulated resistor and is specifically designed for high-voltage, high-current applications. The resistor is composed of a ceramic body, which is sealed entirely for protection and heat dissipation. The ceramic body encloses a robust, high-temperature rated metal oxide resistor. The metal oxide construction is designed to provide a highly reliable, low-resistance circuit when compared to alternative resistor materials.The SQZ15AJB-4K7 is designed to provide electrical resistance in order to control the current flow within a circuit. The resistance is created through an electric field that is created when voltage is applied to the resistor. The electrical field then acts as a barrier, slowing the current, and providing resistance.When the resistor is connected to necessary components within the circuit, and the specified voltage is applied, electrons then pass through the resistor slowly, and the current is reduced to the desired level.

Conclusion

The SQZ15AJB-4K7 is an extremely reliable through hole resistor composed of a ceramic-encapsulated structure. It can be used for a variety of high-voltage, high-current applications due to its metal oxide construction and ceramic body. The resistor works by applying an electric field to the connection points in order to reduce the current flow and provide the necessary resistance for the circuit.
