Through Hole Resistors

Through hole resistors are resistors with leads that are designed to be soldered to a printed circuit board, breadboard, or other electronics project platform. They are used for a variety of applications, such as voltage and current regulation, signal conditioning, and powering a variety of low-voltage electronic devices.The HDM12FA470R is a through-hole resistor that is made up of a fixed, linear resistance element formed by winding a strip of conductive material onto an insulating core. The two ends of the element create two contacts, or leads, which are then soldered to the printed circuit board. This simple construction makes these resistors ideal for long-term, stable and reliable applications.The HDM12FA470R is a radial leaded resistor that has a power rating of 0.125 Watt, 478 ohms of resistance with 5% tolerance and an operating temperature range of -55 to +155°C. It is a non-inductive, axial leaded resistive element that can handle a surge current of 1.2 times the nominal value for at least 5 milliseconds. The dielectric strength of the HDM12FA470R is 350 VDC.The most common applications for the HDM12FA470R are signal conditioning, current and voltage regulation, and a variety of other power supply and protection circuits. Signal conditioning involves adjusting the amplitude, frequency, and/or phase of a signal for a desired purpose. In voltage regulation, the HDM12FA470R is used to reduce high voltages to low voltage levels, allowing for improved system safety and reliability. The HDM12FA470R also has a wide range of applications in power supply circuits, especially in power protection circuits. It is used to limit inrush currents and provide over-current and over-voltage protection. The resistive element of the HDM12FA470R can be used to reduce voltage spikes and protect sensitive components from power surges.The working principle of the HDM12FA470R is fairly simple. The resistive element, made up of a winding of resistive material, creates a resistance value determined by the size of the element. This resistance value can be measured with an ohm meter or simulated in a circuit model. With varying input signals, the current flowing through the resistive element determines the output voltage and current.The resistive element of the HDM12FA470R also provides thermal stability. As the element heats up, the resistance value increases at a predictable rate. This allows for a more stable voltage output, which is especially important when powering sensitive circuitry and components.Overall, the HDM12FA470R is a versatile, cost-effective resistor solution for a variety of applications, from simple voltage regulation to complex signal conditioning circuits. With its high durability and excellent thermal stability, the HDM12FA470R is a reliable, practical choice for many power supply and protection circuits.
