Through Hole Resistors

OL2405E-R52 Application Field and Working Principle

The OL2405E-R52 is a unique technology device that has become widely used in the electronics industry. It is a resistor designed for mature through-hole devices. The combination of its low power and small size makes it suitable for a variety of applications.

Application Fields

The OL2405E-R52 is generally used in various electronic devices, such as computers, electronic clocks, medical instruments, digital cameras, etc. In these devices, the OL2405E-R52 is responsible for limiting the current working in a circuit, maintaining the operating voltage, and adjusting the impedance.Because the OL2405E-R52 is designed with the through-hole mounting holes instead of the notorious surface-mount holes, it is relatively easy to use and install, and sometimes even requires no solder. That’s why when the OL2405E-R52 is used in PCBs (printed circuit boards) that have through-holes, it seems to be widely preferred by engineers and technicians.

Working Principle

The OL2405E-R52 is a resistor with four leads and a cylindrical shape, generally surrounded by a ceramic insulator and some metal. Its resistance is determined by the length and thickness of the cylindrical element, and is measured in ohms.The way the OL2405E-R52 works is simple: whenever a voltage is applied to one of the resistor leads, a current flows through it at the same time. The magnitude and direction of the current depend on the type of resistor and the voltage amount. The current is limited by the load resistance of the OL2405E-R52, meaning the higher the resistance, the lower the current that will pass through it. This is sort of like a valve, where the presence of the resistor regulates the flow of electricity to a certain degree.

Other Important Considerations

Apart from its electrical properties, there are some other characteristics that must be considered before installing any through hole resistor. These include power rating, temperature range, tolerance, and maximum surge. The power rating indicates the maximum amount of energy the OL2405E-R52 can absorb; this is usually indicated by the wattage it can tolerate. Additionally, the temperature range of an OL2405E-R52 should be within the thermal envelope of the application it is being used for, as temperature extremes could cause the resistor to heat up or overheat. The OL2405E-R52 also has a tolerance rating, which is the maximum variation from the nominal resistance in which the resistor will still be considered acceptable. Finally, the surge rating indicates the amount of energy it can absorb without being damaged. In conclusion, the OL2405E-R52 is a versatile resistor used in a variety of applications in the electronics industry, and its special characteristics make it invaluable in regulating the current in a circuit. It is important to consider all the important features mentioned above when selecting an OL2405E-R52 through hole resistor.
