Through Hole ResistorsResistors are electrical components that are configured to create an opposition to the flow of electric current. This opposition, when measured in ohms, is expressed as resistance. Through hole resistors are a type of resistor designed for mounting within printed circuit boards (PCBs) to create networks of electrically connected components. The H412K4BYA is an example of a through hole resistor designed to perform specific functions within a circuit.The H412K4BYA through hole resistor is an axial-lead resistor with a lead spacing of 4.2mm. This lead spacing allows it to fit in printed circuit boards with a cutout of 12mm, or 0.47”, along its length. The body of the H412K4BYA is made of flame-retardant epoxy with temperature resistance and insulation of up to 250°C. This material is embedded with carbon-film resistors to display measured resistance values to within 5%. The resistor also features a power rating of 4W, allowing it to be powered by AC and DC currents of up to 4W or 12V.The H412K4BYA through hole resistor is principally used to control circuit current flow and voltage levels in safety-critical applications within the automotive, medical, and industrial sectors. In automotive applications, the H412K4BYA is used to protect components from short-circuiting by limiting the amount of power passing through the circuit. In medical applications, it is used to protect vulnerable components such as scanners or sensors from overheating. In industrial applications, the H412K4BYA is used to ensure the stability of circuits to prevent electrical noise and disruption. When applied as a through hole resistor, the resistance of the H412K4BYA is changed when current flows between its two terminals. The greater the current, the greater the resistance. This works on a proportional relationship, meaning that when the resistance increases, the current decreases accordingly. When there is no current passing through the resistor, the resistance remains the same. This ensures that the voltage level of the circuit remains stable, even when the current passes through. In addition to its application as a through hole resistor, the H412K4BYA can be used to create a voltage divider. When connected in series with a voltage source, the H412K4BYA can be configured to evenly divide the voltage among the other components in the circuit. This is useful in circuit networks which require separate voltage levels for different components. The H412K4BYA through hole resistor is also known for its versatility. It is capable of functioning in the presence of high-frequency signals, meaning it can be used in many communication and control circuits. It is also designed to handle an operating temperature range of -55°C to +125°C, so it can function in most environmental conditions without becoming damaged. The H412K4BYA through hole resistor is a robust, reliable, and cost effective piece of circuitry that can be used in many different applications. Its flame-retardant epoxy construction and versatile design makes it suitable for applications in automotive, medical, and industrial sectors. The resistor’s robustness allows it to protect components in safety-critical applications, while its ability to handle high-frequency signals makes it an excellent choice for communication and control circuits.
