Through Hole Resistors – MFR-25FRFPN61K9

Through hole resistors are passive electronic components that are used to control and limit the flow of current through an electronic circuit. The MFR-25FRFPN61K9 is a through hole resistor that has a power rating of 25W and a resistance value of 6.1 kilohms. It is used to limit the current in high current applications such as electric motor control, power supplies, and other high-power industrial or automotive applications.

Features of MFR-25FRFPN61K9

The MFR-25FRFPN61K9 is a through hole resistor that has a power rating of 25W and a resistance value of 6.1 kilohms. It has a high thermal stability and is designed to provide reliable performance in a wide range of operating temperatures. The resistor also has a high ripple current rating and a low voltage coefficient which makes it usable in high voltage applications. Its component structural features include a planar coil element with two-straight element pins, an embedded thermistor to protect the device against short-circuit and overload, and a ceramic case to prevent heat buildup.

Applications

The MFR-25FRFPN61K9 is commonly used in various high current applications such as electric motor control, power supplies, and other high-power industrial and automotive applications. In electric motor control applications, the resistor can be used for current limiting and motor speed control. In power supplies, the resistor can be used to limit the current through the power supply when the load is heavy. It can also be used to limit the inrush current to the power supply during startup or when the voltage is increased. In other high-power industrial or automotive applications, the resistor can be used for current limiting, and to provide protection against overloads, shorts, and surges.

Working Principle

The MFR-25FRFPN61K9 works on the principle of Ohm\'s Law. Ohm\'s Law states that the current through a resistor is equal to the voltage across it divided by its resistance value. Thus, by controlling the voltage applied across it, the resistor can be used to limit the current through the circuit. When the resistor is placed in a circuit, the voltage across it is proportional to the current through it. By adjusting the resistance value of the resistor, current can be limited to a safe level for the components in the circuit.In addition, the embedded thermistor in the resistor is designed to protect the device against overloading, short-circuiting, and thermal overload. When the temperature of the resistor exceeds its rated value, the thermistor will activate, limiting the current and protecting the device.

Conclusion

The MFR-25FRFPN61K9 is a through hole resistor with a power rating of 25W and a resistance value of 6.1 kilohms. It is suitable for high current applications such as electric motor control, power supplies, and other high-power industrial or automotive applications. Its working principle is based on Ohm\'s Law and its embedded thermistor helps to protect the device against short-circuit and overload.
