Through Hole Resistors are invaluable components which can be used to regulate current flow or act as a safety factor in a circuit in order to ensure that whatever voltage or current passing through the circuit does not exceed a certain limit. These resistors come in various types, sizes, shapes and capacities, and the HHV-50FR-52-845K is a particularly popular type of through-hole resistor in the market.

The HHV-50FR-52-845K is a heavy-duty, thick-film, through-hole resistor with the ability to dissipate power up to 250 watts. It has a resistance range of 0.5ohm to 800K ohms and can be used in a variety of different applications thanks to its low thermal resistance, high-temperature stability, and exceptional power handling. The resistor is highly reliable and can be used in applications such as over-voltage protection, power supply circuits, and the control circuits of electronic applications.

In terms of installation, the HHV-50FR-52-845K is a surface-mount resistor that is designed to be mounted to a printed circuit board, making it suitable for higher power circuits which demand high dissipation. The resistor is composed of a ceramic substrate and a metal end plate, the resistance is dependant upon the voltage applied across the leads. In addition to this, the heat produced from the resistance is dissipated through the metal plate and into the natural environment, eliminating any further damage to the resistor.

The working principle behind the HHV-50FR-52-845K is the concept of Ohm’s Law and the application of electrical resistance. Ohm’s Law states that the current flow through a resistor is directly proportional to the applied voltage. Thus, with an applied voltage, a certain amount of current will flow through and this current is referred to as the continuous current value. The current flowing through the resistor is usually controlled either by the resistance of the material the resistor is made from or the applied voltage.

When it comes to power handling, the HHV-50FR-52-845K is capable of handling high wattage applications due to its high-power rating and low thermal resistance. The resistor can handle high wattage applications before it reaches its peak dissipation temperature which is usually in the range of 400-500°C. Beyond this temperature, the resistor is subjected to dangerous levels of heat and must be shut down immediately to prevent further damage.

Overall, the HHV-50FR-52-845K is a heavy-duty, thick-film, through-hole resistor which is suitable for high voltage and current applications. Its low thermal resistance, high-temperature stability, and exceptional power handling capabilities make it an ideal component for over-voltage protection circuits, power supply circuits, and other control and monitoring applications. Thanks to its reliance on Ohms Law and its ability to dissipate heat through its end plate, the resistor is capable of handling high wattage and is a reliable and necessary component in any application.
