Through Hole Resistors

OK1155E-R52 is an example of a through-hole resistor, which consists of a resistor element, such as a metal-oxide film, and a body, which is made of ceramic, plastic, or metal, to secure the element into place. The body of the OK1155E-R52 is thermally sensitive so that it can withstand higher temperatures than its standard proportions, allowing it to handle more power with larger currents than its typical counterparts.

The metal-oxide film resists electrical current by creating a barrier for electrons, meaning that the current is forced to go around it, causing the electrons to lose energy in the process. The OK1155E-R52 is able to withstand higher temperatures as previously mentioned because the manufacturers increased the thickness of the film. This allows for faster and more efficient current flow through the resistor due to less energy loss.

The OK1155E-R52 has an operating temperature range from -40 degrees Celsius to 125 degrees Celsius with an increase of up to 150 degrees Celsius with an additional heat sink on the body of the resistor. The total power rating of the OK1155E-R52 is at 5 watts but can be increased with an external heat sink, and the tolerance of the resistor is at ±2%. This means that the amount of current entering the resistor may vary by up to 2%, depending upon the input voltage.

The OK1155E-R52 can be found in many applications from heavy electrical appliances such as industrial equipment and light bulb dimmers, to audio-visual equipment and high-end audio devices like amplifiers and subwoofers. It is used to reduce or regulate the amount of current flowing through a circuit by dissipating the amount of energy into heat. The particular design of the OK1155E-R52 allows for higher performance applications, and the metal-oxide film provides excellent stability while in operation.

In summary, the OK1155E-R52 is a through-hole resistor comprised of a metal-oxide film and a reinforced body, designed to handle more power than other resistors. It can be found in applications like industrial equipment, audio-visual equipment and high-end audio devices. With an operating temperature between -40 and 125 degrees Celsius, the OK1155E-R52 provides an excellent range of performance and stability with its body and its metal-oxide film resistor.
