OK2705E-R52

Through hole resistors are commonly used components that are relatively inexpensive and available in a variety of power ratings and resistance values. The OK2705E-R52 resistor is a through-hole resistor, consisting of a cylindrical carbon film encased in an insulating tube. It is mainly used to provide a default or preset current in a circuit.

The OK2705E-R52 through-hole resistor features a nominal resistance of 5.2K, power rating of 0.5W and a tolerance rate of 5%. It is manufactured using a plated matt carbon film resistor element that is encapsulated within a compact heatsinked thermosetting plastic resin housing, which offers greater mechanical strength and stability in comparison to traditional resistors.

The OK2705E-R52 can be used in a variety of components. Typical applications include power supplies for domestic appliances, audio amplifiers, and audio and signal processing. It is also used in computer system circuits, switching converters, PWM circuits and other power control systems with a low voltage rating.

The working principle of through hole resistors is based on Ohm’s Law which states that the resistance of a conductor is proportional to its length, and inversely proportional to its cross-sectional area. In other words, the longer and narrower the conductor, the higher the resistance. This means that the longer the resistor, the greater the resistance it exhibits.

The OK2705E-R52 resistor works by creating a specific resistance value in the circuit. This helps control the level of current flow in the circuit, which prevents the current from exceeding the designed value. It converts electrical energy into thermal energy, thus providing protection to the circuit. Additionally, part of the resistive energy is dissipated back into the circuit, providing additional control of the current.

In summary, the OK2705E-R52 through-hole resistor is a relatively cheap and reliable component that is suitable for a wide range of applications. Its working principle is based on Ohm’s law and its purpose is to provide a preset or default current within the circuit. It is encapsulated in a hard plastic housing that provides superior mechanical stability and insulation.
