H418R7BZA application field and working principleThrough hole resistors are resistive components that require the use of a hole in a circuit board to mount the component on the board. This hole must connect to an electrical conductor, such as a metal trace or pad on the board, in order to make the component functional. Through-hole resistors have wide application field including DC/AC voltage divider circuits, electrical isolation, amplification circuits, and voltage and current regulation.H418R7BZA is one typical type of through hole resistor which is made from the best grade of carbon film. This type of resistor has high precision and can accurately replicate changes in DC and AC signals. This resistor has been specially designed to provide stability over a wide range of temperatures while still delivering low noise performance. H418R7BZA can be used in a wide range of applications, from small-scale circuit boards to large industrial power systems.The working principle of H418R7BZA is controlling the current passing through it by the resistance it presents to the current. When a voltage is applied to the two ends of a resistor, a current flows through the resistor. The current is proportional to the voltage applied to the resistor (proportional to the voltage/current ratio, V/I). The current will be limited by the resistance presented by the resistor.So when a certain voltage is applied, the current passing through the resistor is determined by the amount of resistance presented by the resistor. This means that if the resistance of the resistor increases, the current passing through the resistor will decrease. The value of resistance is indicated by the resistor’s code and its power rating.For instance, H418R7BZA has resistance of 418 ohms and power rating of 0.5 watts. H418R7BZA can effectively regulate current signals. When the temperature increases, the resistance of H418R7BZA remains stable and this stability makes it suitable for all types of DC and AC voltage and current regulation.H418R7BZA is also suitable for various amplification circuits. This type of resistor is resistant to high temperature and is accurately replicated even when the temperature of the environment changes. This ensures that it can provide uniform performance, stability, and consistency in a variety of amplification application.In short, H418R7BZA has wide application field and is suitable for DC/AC Voltage Divider circuits, electrical isolation, voltage and current regulation, and amplification circuits. It is highly accurate and can effectively resist against high temperature. H418R7BZA can precisely replicate changes in DC and AC signals and ensure steady performance in various application fields.
