Through Hole Resistors are a type of electrical resistor that is used extensively in a variety of applications, from medical devices and power supplies, to consumer electronics and robotics. The HHV-50FT-52-4M99 Through Hole Resistor, in particular, is a figure 8 type surface-mount device primarily used for motor speed control.

The physical attributes of the HHV-50FT-52-4M99 are defined by its dimensions. This device measures 50 mm in length, 45.5 mm in width, with an overall height of 12 mm. It is constructed of flame-retardant resin with a UL94V-0 flammability rating. Also, the HHV-50FT-52-4M99 is RoHS-compliant, meeting the standards for lead-free, halogen-free, and other hazardous materials set forth by the European Union.

The rating of the HHV-50FT-52-4M99 is 0.2 W (at +25 degrees Celsius), a resistance of 5.2 Ohms, and a tolerance of 1%, with an overall track resistance of 4M99. Furthermore, the Through Hole Resistor features a radial axial lead type, with a dielectric strength of 500 V AC (for 1 minute).

The HHV-50FT-52-4M99 is mainly used for speed control, primarily in motor applications. As a resistor, its main function is to reduce the current in an electrical circuit, thereby reducing the voltage and available power. This not only reduces the power demanded by other components in the circuit, it also helps to protect components from damage due to excess voltage.

The Through Hole Resistor works by converting the electricity to heat. Inside the resistor is a nickel-chromium blend, held together by special dielectric material. When electricity is applied to the device, a current begins flowing through the nickel-chromium blend, causing it to heat up. This heat begins to dissipate into the surrounding air, as indicated by the rating of 0.2 W (at +25 degrees Celsius). The higher the temperature of the device, the greater the resistance. Thus, the amount of current flowing through the resistor can be regulated by controlling the temperature.

The HHV-50FT-52-4M99 Through Hole Resistor is a relatively simple device that offers an invaluable service in electrical and electronic circuits. By converting electricity to heat, it provides a safe and efficient means of regulating the flow of current in motor applications.
