Through hole resistors, often known simply as THRs or THT resistors, are a class of electronic components whose purpose is to regulate the flow of electrical current. They achieve this by providing a resistance to the current which, depending on the type, can be either fixed or adjustable. This makes them an essential component to any electronic circuit. The HHV1WSFT-73-240K is a through hole resistor designed to handle the high voltage demands of industrial and telecom applications. This article will examine the application field and working principle of HHV1WSFT-73-240K.

The HHV1WSFT-73-240K is a Non-Inductive, High Voltage, Wirewound Resistor, designed for industrial and telecom applications. The resistor offers magnetic shielding, allowing it to be used in DC-DC converters, UPS systems, lamp ballast, and power supplies requiring higher voltage and current ratings. The device is capable of handling rated power of 50W in a short timeframe of 15 seconds and is non-inductive, meaning it will not produce a magnetic field. Maximum working voltage of the device is 2400V.

The resistor is built with a construction that ensures high performance and reliability. It features four layers with a glass-fiber reinforced insulation layer ensuring low particle emission and heat decrease of up to 20C, even after continuous exposure to high temperatures. Additionally, it features a special material for element connection with high cold-bar insulation, resisting up to 25kV. The resistor has a compact construction to facilitate mounting and stress on the connections is eliminated.

The working principle of the HHV1WSFT-73-240K is based on the Standard Ohm’s Law, i.e. voltage (V) is related to current (I) and resistance (R) by V = I x R. In the case of the HHV1WSFT-73-240K, this means that as current flows through the resistor, it encounters resistance which then creates a voltage drop across the resistor. This voltage drop is dissipated as heat, which is then cooled by the four layers of insulation. The total power dissipated can be found with the formula P = V x I.

In conclusion, the HHV1WSFT-73-240K through hole resistor is an essential component for industrial and telecom applications requiring high voltage and current ratings. Its construction guarantees excellent performance and reliability, and its working principle is based on Ohm’s Law. The device is the ideal solution for applications that require a robust and efficient resistor.
