Through Hole Resistors

HHV-25JR-52-20K application field and working principle

Through hole resistors, also known as “wire wound” resistors, are one of the most popular resistors used in various electronic application fields. HHV-25JR-52-20K is a type of through hole resistor and features a high temperature coefficient resistor whose application field is limited to very high temperature applications, such as welding and induction furnaces.

The working principle of this type of resistor is based on the principle of electrical insulation. This means that when electricity passes through the resistor, it remains within the component and does not cross the conductors, enabling the resistor to function properly. To achieve this, the resistors are made out of a special metal that is resistant to heat, insulates the electric current, and is also highly resistant to corrosion.

The resistors are also coated with a special insulation material such as polyester, ceramic, or EPDM, which prevents arcing and helps reduce the wear and tear of the device. HHV-25JR-52-20K is generally designed to withstand temperatures up to +250°C for a maximum of 16 hours. This makes it suitable for various applications, including furnaces, ovens, and other temperature-sensitive applications.

In addition, they are also designed to absorb and dissipate heat effectively, which helps them to last longer and offer better performance. Furthermore, HHV-25JR-52-20K exhibits excellent stability and has good tolerance to moisture and corrosion, making it an ideal choice for use in humid environments.

To achieve the desired resistance with the least danger of any breakage, the resistors are made with a combination of different coatings. These coatings are designed to form a protective layer around the resistor, which not only prevents breakage, but also helps to maintain consistent resistance over time.

HHV-25JR-52-20K is a highly reliable through hole resistor and is widely used in many applications, from consumer electronics to industrial applications. It is an important component for many electronic systems and is well suited for use in high temperature and corrosive conditions. It is an excellent choice for a wide range of application fields because of its excellent performance in both high and low temperature environments.
