Through Hole Resistors is a major category of electronic components. OF131JE is one of the representatives of this category. Next, let’s introduce its application field and working principle.

OF131JE belongs to the wirewound resistors, its appearance is usually cylindrical, sometimes can also be box-shaped. It is widely used in various types of electrical equipment, such as electric refrigerator, microwave oven, electronics and household appliance etc. TO meet the requirements of modern small high-power high-speed electronics, OF131JE can be used for power-on current car, anti-surge, flash protection, overtime fault current, emergency stop, etc. Furthermore, as its excellent performance of lightning protection, it also can be applied in elevator, transformer and other equipment.

Now let’s talk about its working principle. It belongs to a resistors that uses the wirewound type in which power is dissipated in the windings of an insulating bobbin or the other ways of dissipation. OF131JE’s electrical resistance of winding wire was placed in an epoxy case, which is formed by insulating, resistive, and heat-transfer layers with high temperature resistance. Its resistance can be changed via adjusting the length of the wire or by changing the width of the cross-section of the wire. And its resistance is generally stable and accurate, with power rating up to 4W, voltage rating can reach up to 3KV. The features such as corrosion resistance, moisture proof, low temperature rise, and good stability. Also, the internal structure can strongly reduce the noise emitted.

In conclusion, OF131JE’s application field is very wide, and it is a very useful electronic components. It is also easy to use and has a good working performance. It is indeed a good choice for customers.
