Through Hole Resistors are a type of component used to control and limit the current running through an electric circuit. The RSMF3JT2K40 from Vishay/Dale is one such series. This versatile through hole resistor is used in various power delivery, telecom, wireless communications and other applications.

The RSMF3JT2K40 is a 3 watt, 0.25 ohm, non-inductive, through hole resistor that is being manufactured to a J-lead configuration. It utilizes a power plane for heat dissipation which makes it suitable for high power applications. The power rating and power dissipation capabilities of this component are impressive for its small size.

This series of resistor also features a ceramic-coated flammability rating of UL 94V-O so it can easily be incorporated into consumer and automotive applications. The overvoltage protection feature also makes it ideal for use in a variety of high voltage applications. The resistor is engineered to handle up to 200V peak surge without compromising safety and its high thermal conductivity ensures that heat is effectively removed from the component.

The RSMF3JT2K40 also has a wide operating temperature range of -55°C to +205°C. This makes it well suited for use in extreme temperature environments. This component is available in both axial and surface mount packages. It is rated for a maximum power dissipation of 3 watts, making it ideal for a variety of applications including power conversion, telecommunications, industrial control, and automotive.

The working principle of the RSMF3JT2K40 is relatively simple. It is a Resistive-Capacitive (RC) or resistive-Inductive (RL) component that acts as a resistor in a circuit. When a voltage is applied across its terminals, current flows through its resistor element, resulting in a drop in voltage across the resistance. This voltage drop is known as the Voltage Drop Across the Resistor (VDAR). The resistance value of the resistor is proportional to its current carrying capacity, and is determined by its resistance value. As VDAR increases, the current through the resistor also increases, resulting in increased power dissipation.

The RSMF3JT2K40 is an ideal component to use in various applications including power conversion, telecommunications, industrial control, and automotive. Its small size and high power rating make it ideal for a variety of applications. Its good thermal conductivity ensures that heat is effectively dissipated, while its high voltage protection feature keeps it safe from potential over-voltage failures. The series is available in both axial and surface mount packages, making it suitable for many different types of applications.
