Through-hole resistors are components that use a metal-framed resistor in the electronic device. The metal-framed resistor, or also known as the carbon composition resistors, consists of compressed carbon pellets or paste, ceramics and metal materials. This is then wrapped with an insulating tape before finally being encased within a metal-in-a-tube which provides shielding from environment elements and also increases thermal control. The HHV-25FT-52-162K resistance model is one of these resistors.

The most common application for the HHV-25FT-52-162K through hole resistor is for high voltage and high frequency applications. This resistor is designed to provide a rated resistance between 0.02 and 0.25 Ohms. Its rated power is between 2 watts and 22 watts. It also has an operating temperature range between -55°C and 125°C. This model operates in an intermittent temperature range of up to 175°C and a heat shock temperature up to 300°C.

The working principle of the HHV-25FT-52-162K through hole resistor is based on the general property of resistors. Electricity rushing through a conductor generates heat due to the collisions with the atoms which make up the material. The resistance regulates the amount of electricity that passes through the conductor, and hence governs the heat produced in the process.

The HHV-25FT-52-162K through hole resistor is constructed with premium materials that offer a significant degree of durability and reliability even under the extreme operating conditions. The ceramic material floor ensures homogeneous heat distribution, which helps reduce hotspot temperature formation during continuous operation. The wire connecting the resistor leads is metal-framed silver wire with a silver coating. This helps to attain the theoretical rated resistance value and allows the resistor to handle up to a rated energy of 22 watts.

Finally, the resistor is encased in a robust metal-in-a-tube that maximizes heat dissipation, prevents debris entry and provides electrical insulation. The resistor is also equipped with a terminal loop for connecting to external connection points. The terminal loop is connected to epoxy coated terminals with crimped ends. This further enhances the holding force between the resistor and its terminals, allowing an even distribution of stress.

In conclusion, the HHV-25FT-52-162K through hole resistor is designed for intermittent operation with a rated power of up to 22 watts and a resistance range of 0.02 to 0.25 Ohm. It features a robust metal-in-a-tube casing and epoxy coated terminals with crimped ends. These components make it suitable for high voltage and high frequency applications.
