Through Hole Resistors refer to a family of resistors that requires manual installation into a circuit board. In this family, the Metal Oxide Film resistor (OF270JE) has been a popular choice for its small size and stable performance for over sixty years. This article will explain the application fields and working principles of the OF270JE resistor.

An OF270JE resistor is built by taking a metal Oxide Film which is then wrapped around an insulator. The construction of the resistor is usually made of high-temperature ceramic and then undergone a vacuum drying process. With this construction, the OF270JE has proved to be extremely stable in a wide operating temperature range and offers excellent frequency response. This in turn makes it an excellent choice for use in automotive, audio, TV and other appliance applications.

The working principle of the OF270JE is relatively simple. As electrical current passes through the resistor, a percentage of it is converted into heat energy. This excess heat energy is then dissipated by the built-in cooling system of the resistor. The electrical resistance of the resistor is determined by the material resistance of the metal Oxide Film. Generally, the higher the resistance of the material, the higher the resistance of the resistor.

The OF270JE resistor is usually used to control the current flow within a circuit, providing protection to the sensitive components nearby due to its stable characteristics. Furthermore, the OF270JE is able to operate in a wide temperature range, making it suitable for use in different environments, from automotive to commercial electronics.

In addition to being an economical choice, the OF270JE resistor also offers other benefits, such as its extended service life. The resistor is a reliable component, meaning that it can last for a long time, even when exposed to harsh temperature and environmental conditions. Also, its small size makes it easy to mount on circuit boards, making it an ideal choice for space-limited applications.

Overall, the OF270JE is an easy to use yet reliable solution for many different applications. Its reliable performance, large operating range and simple management make it a popular choice for many engineers and technicians. Furthermore, it is an economical choice for those looking for an inexpensive but dependable resistor solution.
