OY473KE through hole resistors are extensively used in a wide range of applications. These include power adaptors, power supplies, media players, audio amplifiers, cable box converters, portable battery chargers, electric gates, automotive electronic circuits, PLCs, and microprocessors.Through hole resistors are also used extensively in telecommunications, providing telecommunications companies with a cost-effective way to construct reliable systems. These include:• High-speed fiber-optic cables• Solar electric systems• Digital switching systems• Antenna matching equipment• Radio-frequency amplifiers• Voice-over-IP (VoIP) systems• Automotive telematics• Data transmission systemsThrough hole resistors are a form of passive electrical component that is designed to control and reduce the flow of electrons and electric current through a circuit. They are designed to resist electricity flow and are available in a variety of sizes, shapes, and types. When two resistors are placed in series, they reduce the total resistance across a circuit.Through hole resistors come in two basic configurations: axial and radial. The axial mount type is used in most modern applications. This includes installing the resistor in printed circuit boards (PCBs), as well as connecting two wires together.The axial mount type of resistor is usually made up of a metal cylinder with two leads that extend from the end. These leads are connected to a body that contains a carbon or ceramic core. Resistance is reduced as current passes through the core.The radial variant is designed for quick mounting and replacement and is usually found in automotive applications. It is made up of two concentric circles of metal with a core composed of carbon or ceramic in the center. The outside of the circles is insulated from the innermost layer.Through hole resistors are usually made up of ceramic, plastic, or metal materials. Depending on the application and desired resistance, they can be manufactured using different materials and techniques.For example, a resistor in a power regulator could require a high insulation value. In this case, a ceramic material with a shell filled with glass is best. To offer high accuracy and a high temperature coefficient of resistance (TCR), a metal-alloy material is used for high-precision resistors.In terms of working principle, these resistors are designed with a fixed resistance value in mind and have very low tolerance levels. This means that they will only be able to handle a set amount of electrical current before it begins to rise significantly. To help balance the resistance along the circuit, multiple resistors may be placed in series or parallel to reduce the overall resistance.In addition to helping balance resistance throughout a circuit, through hole resistors also help protect sensitive equipment by limiting the current flow to a desired tolerance level. They also help stop power surges or spikes from damaging a device or circuit.In conclusion, OY473KE through hole resistors are widely used in many applications and provide a cost-effective way to provide circuit protection and stabilization. They are available in a wide range of sizes, shapes, and types, and come in both axial and radial configurations. They offer a fixed resistance value and are designed to provide reliable operation and protect sensitive equipment.
