Through hole resistors provide a reliable method of attenuating or dissipating power to electrical and electronic circuits. A 41F470 is an example of a through hole resistor that is designed for use in a particular application and works through a specific principle.

Specifications

The 41F470 is a radial leaded through hole resistor with an insulated body and features high adherence to flame. The resistance range gives 380 ppm/K, ±5-25%, NTC 10KΩ~ 100KΩ, insulating to 400V, and with curve to 60/40. It also features low resistance values and low thermal electrical noise. Additionally, it is RoHS-compliant and halogen-free.

Applications

The 41F470 is often used as a low thermal electrical noise resistor for power distribution, motor control, noise suppression, and inverter power control in various automotive and manufacturing electronics. With its flame retardancy, the 41F470 is also well suited to provide protective overcurrent limiting during the fusion welding process in manufacturing. Additionally, it is employed in household appliances and equipment, heating and air conditioning units, electric vehicle power electronics, and LED lighting, among other devices.

Working Principle

The operating principle of 41F470 is based on Joule heating. When voltage is applied on the resistor (which is made up of a metal film), an electric current traverses it, producing a drop in voltage that is proportional to the value of the resistance. This voltage drop generates heat due to the resistive nature of the material. The heat is dissipated to the outside world due to its insulation. The larger the current, the more heat dissipated.

The resistor also responds to changing temperatures by modifying its resistance. As a result, the material\'s characteristics are important for the resistor to more efficiently dissipate the heat produced. The 41F470 is specifically designed to have a lower thermal coefficient of resistance, resulting in better heat dissipation with low thermal electric noise.

Benefits

The 41F470 provides a reliable and robust means of attenuating and dissipating power to the circuit. Its insulation allows for operations even under high temperature and high voltage applications. As an important electrical component, it has low resistance values and low thermal electrical noise. This makes it suitable for multiple uses in the protection of circuit boards and other sensitive electronic appliances.

In conclusion, the 41F470 is a through hole resistor that is designed to offer high durability and adhesion to flame. It finds application in many different devices, including motor controls, power distribution, inverter power control and noise suppression. The operating principle of the device is based on Joule heating and is designed to have a low thermal coefficient of resistance, making it an ideal device for power attenuation or dissipation.
