Through Hole Resistors

Through hole resistors are resistors used in electronic circuits that must be inserted into holes drilled in printed circuit boards (PCBs). The name through hole comes from the fact that the lead wires of the resistor must pass through a hole in the PCB before they are soldered into place. Through hole resistors are a type of discrete component, meaning they are individual components rather than integrated circuits, and they serve an important role in circuit design. By connecting these resistors in different ways, electronics engineers can create circuits with almost any characteristics they desire.

The RLR20C3603GMRSL is a through hole resistor manufactured by TDK, and has a rated power of 0.25W, resistance of 360 KΩ, tolerance of 5%, and a maximum voltage rating of 250V. It is available in either a carbon film or metal film construction which will determine the temperature coefficient of the resistor. The construction is also important for determining the noise and inductance values of the resistor. This through hole resistor is suitable for use in applications where a low noise audio level precision is required, such as in amplifiers or headphones.

Working Principle

The working principle of through hole resistors is the same whether it is a carbon film or a metal film type. These resistors are placed in a hole in the printed circuit board and the lead wires are then passed through the hole and soldered into place. When current passes through the resistor, a small voltage drop is created which is proportional to the resistance of the resistor.

The size of the voltage drop can be controlled by varying the resistance of the resistor and this is done by changing the type of film that is used to constrict the resistor. Carbon film resistors are the most common type and are made from a thin film of carbon sandwiched between two metallic layers. These resistors are usually reliable and have low noise and temperature coefficient values.

Metal film resistors are more accurate than carbon film types and are normally used in more sophisticated circuits. These resistors are made from a thin film of metal which is deposited onto a ceramic substrate. This type of resistor has better noise characteristics than carbon film types and is also more resistant to temperature changes.

Applications

Through hole resistors such as the RLR20C3603GMRSL have a wide range of applications due to their accurate performance and reliability. They are commonly used in audio and signal processing circuits, communication circuits, control circuits and power supply circuits. They are also a popular choice for automotive applications due to their small size and reliable performance.

The RLR20C3603GMRSL is suitable for use in systems requiring a low noise audio level precision, such as audio amplifiers, headphones and even medical equipment. It is also suitable for use in control circuits and power supply circuits that require accurate voltage and current measurements. By connecting these resistors in different combinations, the electrical characteristics of the circuit can be changed, enabling engineers to customise circuits with almost any functionality they desire.

Through hole resistors are also important for safety reasons as they can be used to limit the amount of current passing through a circuit thereby preventing voltage spikes and overloads which can damage sensitive components and cause system failures. The resistors can also be used to reduce static electricity in sensitive circuits which helps to protect delicate components from damage.

In summary, the RLR20C3603GMRSL is a through hole resistor manufactured by TDK. It is suitable for use in audio and signal processing circuits, communication circuits, control circuits and power supply circuits. It has a low noise audio level precision and can be used to safely limit the amount of current passing through a circuit. Through hole resistors such as this are an important component in many different applications.
