Through Hole Resistors are components used in electronic circuits to reduce current flow and vary signal levels. The PSP500KR-4K7 is a Through Hole Resistor designed with resistance range of 4K7.

The main application field of PSP500KR-4K7 is related to power circuits. It can be used as current limiter, current protection, voltage dropping, generator control and voltage stabilization in any power supply application, as the resistor can control the voltage and current. PSP500KR-4K7 is also useful in circuits that convert AC to DC such as AC/DC inverters, solar inverters and adaptors. Furthermore, it prevents devices from back-emf by stabilizing the power supply. It can also be used for preventing voltage overload and short-circuit protection, as well as pulsed circuits with high-frequency power inproducts.

The working principle of PSP500KR-4K7 is based on the resistance it offers when conductors experience an electrical current. The resistance of a resistor is determined by its physical construction. The PSP500KR-4K7 contains a metal oxide layer, the resistance of which is given in ohms. When a current passes through the resistor, it experiences a voltage drop across it due to the resistance. This voltage drop is used to regulate current flow. The PSP500KR-4K7 is designed with a 4K7 resistance or 4700 ohms meaning it causes a voltage drop of 4.7 volts when a current of 1 ampere passes through it.

The PSP500KR-4K7 is rated up to 500V maximum and can withstand up to 1W of power dissipation. Additionally, it features a high temperature coefficient of 1000 ppm that improves its reliability and ensures a voltage drop of 4.7V even at a temperature of 125°C. The resistance of the PSP500KR-4K7 remains within the tolerance of ±5% over its specified temperature and power ratings. The resistor also features an insulation resistance of 40MΩ, meaning it can be operated at safe voltage levels and is suitable for most electronic devices.

PSP500KR-4K7 Through Hole Resistor can provide reliable voltage drop, resistance and current protection in power supply applications. Its high thermal coefficient and high insulation resistance make it a good choice for temperature and power sensitive applications. The resistor is available in a wide range of sizes and packages and is a cost-effective solution for voltage and current regulation in power supplies.
