Through Hole Resistors are resistors which have external leads that pass through a rigid insulation material to achieve mechanical stability and electrical isolation. This type of resistor is formed by mounting two or more metal pieces on a board and then attaching external leads or wires to it. The most common type of through-hole resistors is the PF2205-5RF1. This type of resistor is widely used in various electronics circuits due to its excellent features.

The PF2205-5RF1 has a rated power of 5W and a resistance range of 1OHM to 10KOHM. It is a non-inductive type of resistor and can be used with both AC and DC signals. It also has a high temperature coefficient of ±25ppm/oC and a tolerance of ±1%, making it suitable for use in higher precision circuits. Furthermore, its operating temperature range is -55C to +155C and it can withstand a peak temperature of 200C. The package size of the PF2205-5RF1 is 3.5mm x 15.0mm x 16.5mm and its weight is 3.3g.

The PF2205-5RF1 can be used in applications such as power supplies, SCR/Thyristor circuits, telephone and line-feed circuits, and heaters. It is also suitable for use in other applications requiring high temperature and thermal stability. The device has an insulation resistance of 1000Mega-ohm at 500VDC, which ensures it is highly reliable in operation. Moreover, it has a resistance tolerance of ±1% and a voltage coefficient of ±50ppm/V.

The working principle of the PF2205-5RF1 is based on the generation of electrical resistance in the metal contacts. When the metal pieces are connected to an external source of electricity, a current passes through the device and generates resistance in the metal contacts. This resistance is then used to regulate the current flow in the connected circuit. The amount of resistance produced depends on the voltage applied to the resistor and the type of metal used.

In conclusion, the PF2205-5RF1 is a popular through-hole resistor used in many types of electronic circuits. Its small size and excellent features make it suitable for use in high precision applications. Furthermore, it has an insulation resistance of 1000Mega-ohm at 500VDC, ensuring it is highly reliable in operation. It has a resistance tolerance of ±1% and a voltage coefficient of ±50ppm/V. Moreover, it can withstand temperatures up to 200C. This makes the PF2205-5RF1 an ideal choice for use in high temperature and high-precision electronic applications.
