Through Hole Resistors

FMP-50FR-52-20K Application Field and Working Principle

Through-hole resistors, referred to as through-hole resistors, are resistors with metal wires threaded through a hole in the middle of the resistor and soldered to the circuit board. The resistance value is determined by the length, cross-sectional area, and material of the metal wire. The greatest feature of through-hole resistors is that they can be used in circuits that are more sensitive to high temperatures, allowing them to be more widely used in harsh environments. The other advantage of through-hole resistors is that they are easier to replace than regular resistors, since it is much easier to remove the terminal wires than to remove the legs of the resistor.

FMP-50FR-52-20K resistors are one of the types of through-hole resistors available. The resistance value of this type of resistor is 20kΩ. These resistors are made from a nickel alloy construction, which makes them less susceptible to noise and vibration, as well as temperature changes. These resistors are ideal for high power applications, such as in automotive, industrial, and aerospace systems, as they can withstand up to 7 watts of power without damage. The temperature range for these resistors is -55°C to 155°C, and they have a vibration resistance range of 20G.

The working principle of through-hole resistors is relatively simple. The resistor contains a thin metal wire that is threaded through the center of the resistor, which is usually made of a ceramic or plastic material. The metal wire is then soldered to the circuit board. When a current passes through the wire, the resistance of the wire causes the current to be reduced, thus allowing for the current to be regulated or used to change the voltage. Through-hole resistors are used in a variety of applications, such as regulating voltage in a circuit, providing a constant current source, and filtering out noise.

In summary, FMP-50FR-52-20K resistors are a type of through-hole resistor that is designed for high-power applications. The resistance value of these resistors is 20 ohms and they are made from a nickel alloy construction, making them less susceptible to noise and vibration, as well as temperature changes. These resistors are ideal for automotive, industrial, and aerospace systems, as they can handle up to 7 watts of power without damage. The working principle of these resistors is relatively simple and involves the use of a thin metal wire that is threaded through the center of the resistor and soldered to the circuit board, which is then used to regulate current and voltage in a circuit.
