HHV1WSFT-73-4M99Y

Through Hole Resistors are ideal as permanent parts for a variety of electrical or electronic applications. This is due to their sizeable form factor that provides more than enough mounting surface-area, and durability compared to their surface mount counterparts. One particular through hole resistor is the HHV1WSFT-73-4M99Y, and this article will discuss its application fields, and working principle.

The HHV1WSFT-73-4M99Y is an axial leaded resistor. It has 4.7K ohms of resistance and has a tolerance rating of ± 1%. It is rated for operation up to 300 degrees Celsius. This type of resistor is generally used in high-power circuit applications, audio systems, linear actuators, and light dimming fixtures. As far as high-power use, it is commonly used in the switch mode power supplies in computer networks, as it has high wattage resistance and unidirectional flow characteristics that prevent too much current from being sent to the circuit.

The HHV1WSFT-73-4M99Y also has a substantial physical mass, making it popular in automotive electrical applications. Its shape contributes to its ability to dissipate heat, making it ideal for automotive readouts, power amplifiers, and other high-dissipation situations. Additionally, its extremely low temperature coefficient of resistance (TCR) under 0.005%, which makes the resistor suitable for circuit applications requiring stability and reliability.

The HHV1WSFT-73-4M99Y is a non-inductive resistor, meaning it does not induce any non-linearity or distortion in the electrical signal. The resistor is made from a single metal or ceramic substrate, which is then coated with a metal film. This is followed by depositing an insulating layer on top of the metal film. This combination provides the resistor with its resistance and insulation properties. The metal film is composed of nickel, chromium, or manganese. These metals are chosen for their resistance values, and their ability to remain stable over various environmental and temperature fluctuations.

The resistor\'s resistance value is determined by the thickness of the metal film and the dimensions of the resistor. The width of the metal film determines the amount of current that can flow through the resistor. The body of the resistor, on the other hand, regulates the amount of current that can flow through it. This regulation ensures that no current will flow into the electrical circuit if the resistor is subject to voltage surges.

The HHV1WSFT-73-4M99Y is generally recommended for temperature-sensitive applications due to its high operating temperature and its ability to remain stable over a wide range of temperatures. It is also desirable in automotive and other industrial applications due to its low temperature coefficient of resistance (TCR), which provides a reliable and consistent electrical signal.

In conclusion, The HHV1WSFT-73-4M99Y is a through hole resistor whose optimal form factor makes it well-suited for high power electronics applications such as switch mode power supply, audio systems, linear actuators, and light dimmer fixtures. Its reliability and consistency, as well as its spacious mounting surface-area and its high wattage resistance, makes it an ideal part for long-term applications.
