Through hole resistors are passive electronic components used to provide a specific and precise amount of resistance in an electrical circuit. The isovalent HHV-50FB-52-2M8 is one of the many types of through hole resistors available on the market. It is a wire-wound resistor that can handle higher power up to 50 W, making it perfect for applications with higher power demands.

This component is a 50 Watt wire-wound resistor with a 5% tolerance, meaning that they can be very precise when providing the desired resistance. The resistance range for this particular through hole resistor is 2 Megaohms turning the HHV-50FB-52-2M8 into a great option for many different applications.

Its Applications field includes providing resistance for current limiting, filtration, snubbing, pulse applications, and any other high power circuit requirements. HHV-50FB-52-2M8\'s are often used in switching power supply, welding electronic control equipment, power amplifier and other high-power apparatus. The advantage of this through hole resistor is its higher power rating and wider tolerance range.

The working principle of wire-wound resistors is based on Joule heating. When electricity passes through a wire, the current squeeze and agitate the atom molecules, which causes friction, vibration, and therefore heat. Different amount of current causes different amount of heat. When a desired value is arrived, the current is limited. As like this, the wire-wound resistor is design to reduce or limited current flow by means of heating effect.

In general, the core structure of the wire-wound resistors is composed by an insulating substrate, wires and a resistor coating film. The insulating substrate typically made by Fiberglass-Reinforced polyimide film, known as FR-4, is to house and hold the wires in place. The wire used can either be copper alloys, Nickel, or nickel Chrome wires with round or flat surfaces. The resistor coating film is a type of material which is usually made by either an organic or inorganic material that will protect the wires and improve the electrical resistance performance.

The HHV-50FB-52-2M8 is a through hole wire-wound resistor which maximizes the performance and allows for a very high power rating. It is designed for applications that require a high power rating and makes a great choice for switching power supply, welding electronic control equipment, power amplifier and other high power apparatus.
