Through Hole Resistors are one of the most frequently used passive components in electrical engineering. Their main purpose is to limit, adjust or stabilize electrical current. One of the most popular types of through hole resistors are the 85F40K2.

The 85F40K2 is a Through Hole Resistor that has a power rating of 40K (Kilo) ohms, and a tolerance of +/- 5%. These Resistors have a 0.2W (watt) power rating, and maximum exposure temperature of 85°C. The operating temperature range is -55°C to +125°C.

The general application fields of the 85F40K2 are for general purpose electrical applications such as adjusting current and providing protection for transistor and circuit boards. These resistors are also used in the protection of shunt sensing circuits, where a current limiting effect is needed.

In order to understand the working principle of the 85F40K2, it’s important to first understand the concept of Ohm’s law. Ohm’s law defines the amount of voltage which is needed to create a certain amount of current in a circuit. The amount of voltage required to create the desired current is equal to the amount of resistance in the circuit, multiplied by the amount of current needed. Knowing this, one can understand how the 85F40K2 works.

The main purpose of the 85F40K2 is to provide a stable amount of resistance in order to limit the current in a given circuit. The amount of resistance the 85F40K2 provides in a given circuit is fixed, or described by it’s resistance value. The resistance value of this resistor is 40K ohms, meaning that the resistor is providing a resistance of 40K ohms in the circuit.

The 85F40K2 is designed to operate under high temperatures, and it’s maximum temperature is 85°C. This feature makes it perfect for applications which require high temperature environments. Due to its high temperature range, this resistor is suitable for use in equipment such as amplifiers, motors, and other heat generating electrical equipment.

Due to its 40K resistance value, the 85F40K2 is often used in current limiting circuits. It acts as a buffer in the circuit, and helps to prevent excessive current from passing through the circuit. This helps to protect both the circuit and any components connected to it. The 85F40K2 is also suitable for use in voltage dividers, temperature measurements, and as a base resistor for other components.

In conclusion, the 85F40K2 is a Through Hole Resistor with a power rating of 40K ohms and a tolerance of +/- 5%. It has a power rating of 0.2W and a maximum exposure temperature of 85°C. It is generally used in general purpose electrical applications, such as adjusting current,providing protection for transistor and circuit boards, and in shunt sensing circuits. This resistor is also suitable for use in current limiting circuits and voltage dividers.
