Through Hole Resistors

Through hole resistors are a type of resistor designed for use as part of an electrical circuit. They are able to perform similar functions to surface mount resistors, but differ in how they are attached to a circuit board. Rather than use solder to attach the resistor to the board, a metal or ceramic mounting body surrounds the resistor, forming what is known as a “through-hole”. This style of design allows for easier repair and modification of a circuit board.

RWR78S1000FRB12 is one such example of a through hole resistor. This resistor has a resistance of 1,000 Ohms and is part of the RWR78 series of resistors. It has an operating temperature range of -65 to +135C (-85 to +275F). This resistor is best used in environments that require reliable performance over a wide temperature range.

The working principle of a through hole resistor is simple. The resistor is connected to an external circuit via two leads. When an electric current flows through the resistor, it absorbs a portion of it, resulting in a drop in voltage across the resistor. The magnitude of the voltage drop is dependent on the resistance of the resistor. This resistance typically remains constant within a given environment but may decrease in higher temperature environments.

The application field for the RWR78S1000FRB12 resistor is vast. It can be used in a wide variety of applications, including audio circuits, power supplies, and amplifiers. It is also commonly used in motor control circuits or systems requiring a current limiting switch. In automotive applications as well, it is commonly used in circuit protection devices and air bag systems.

The RWR78S1000FRB12 is a versatile component that offers reliable performance in a wide range of conditions. With its robust design and wide temperature range, it is a reliable through hole resistor for any circuit board.
