Working Principle of MFR100FTF52-56R

The MFR100FTF52-56R is based on the standard two-terminal resistor design. It uses metal films as the resistive medium instead of the traditional carbon composition resistors. These metal films provide a low resistance value and higher power rating. The resistor has a thicker film on the top and bottom lay of the resistor which provides the heat sinking capability.

The resistance of the metal film in the MFR100FTF52-56R varies with the temperature. The resistance of the metal film increases with increase in temperature. This behavior is known as the positive temperature coefficient. This behavior is beneficial in applications where the temperature of the circuit needs to be controlled.

The MFR100FTF52-56R also has an epoxy coating over the metal film which protects it against abrasion and short circuits. The epoxy also protects against moisture and other contaminants. The epoxy also increases the voltage rating of the resistor.

The MFR100FTF52-56R has a wide operating temperature range from -55℃ to +150℃. It has a high power rating of 1W and the resistance value ranges from 150 ohms to 5.6K ohms.
