Through Hole Resistors refer to a class of resistors in the discrete components family, which are mainly used to limit the current flowing through an electronic circuit. Aside from these basic functions, through hole resistors also have other characteristics such as providing a voltage drop for certain components, forming a part of a filter circuit, and providing controlling features. The OK8205E-R52 is a high precision device that has applications in the field of digital signal processing, analog measurement devices, power monitoring, antennas and various industrial device. It is also ideal for use in the telecommunications industry.

The OK8205E-R52 is a MOS-FET type three-terminal through hole resistor, with an extremely low resistance tolerance of ±0.2%. The device features a wide temperature range of -40℃ to +125℃ and a standard resistance range of 5Ω to 5KΩ. It utilizes a special construction technique, which improves the device\'s reliability and easy mounting onto printed circuit boards.

The working principle of the OK8205E-R52 is quite simple. It is a three-terminal resistive device consisting of a source terminal, drain terminal, and a gate terminal. The source terminal voltage and drain terminal voltage are set to the desired value, and the gate terminal is connected to a control voltage or an operating point voltage. This causes the device to act as a resistor with a resistance dependent on the gate control voltage.

In order to use the OK8205E-R52 in a circuit, the voltage at the source and drain terminals must first be set, and the gate voltage must then be adjusted depending on the desired value of resistance. The resistance of the device will depend on the magnitude difference between the source and gate voltages. As the magnitude difference increases, the resistance will also increase. Thus, the OK8205E-R52 can easily be used to control both current and voltage in a circuit.

The use of the OK8205E-R52 also ensures that the circuit does not get damaged due to overcurrent. The device comes equipped with a current limiting feature that responds to any sudden increase in current and reduces it to safe levels, ensuring that the rest of the circuit remains undamaged.

Another major benefit of using the OK8205E-R52 is its low self-heating attribute. The device exhibits very low power dissipation, which eliminates the need for extensive heat sinks and other cooling solutions. This further translates into low overall operating costs for the user.

In summary, the OK8205E-R52 is an excellent choice for use in the fields of digital signal processing, analog measurement devices, power monitoring, antennas and various industrial devices. It offers excellent resistance performance, precision control, and high reliability while also reducing heat dissipation and providing protection against excessive current flow.
