MFR-25FRFPN12K4

Through Hole Resistors

Through-hole resistors, also called leaded resistors, are components that are used to provide resistance to a circuit. The name ‘through-hole’ is because these resistors are fitted by passing their leads through a hole in the component board, and then securing them to the board with a soldering tool. Through-hole resistors are easier to use than other types of resistors because their leads can be bent into position and securely soldered in place on the board. They are also easier to inspect and can come in a variety of sizes and configurations.

MFR-25FRFPN12K4 application field and working principle

The MFR-25FRFPN12K4 is a through-hole resistor with a nominal value of 12 kilo-ohm (K4). It is available in several sizes and has a tolerance rating of ±2%. This device is used in a wide variety of applications, including automotive, communications, industrial and medical, where a relatively high resistance is needed. The working principle behind this resistor is simple: when a current passes through, the resistor ‘resists’ it and dissipates the energy as heat. The higher the resistance, the less current will flow through, and the more heat that will be generated.

MFR-25FRFPN12K4 can be used in circuit designs where a relatively high resistance is desired. This could be in an electronic circuit that requires a specific resistance to be maintained, or in a circuit that controls the current flow in an LED or other device. The device is also suitable for use in high voltage applications, as it has high stand-off voltage, and is capable of handling much higher voltages than lower resistance devices.

The MFR-25FRFPN12K4 can be used in conjunction with other devices, such as capacitors or voltage regulators. When used with a voltage regulator, it can be used to reduce the voltage output to a desired level. When used with a capacitor, it can be used to control the output current from the capacitor.

It is important to note that the MFR-25FRFPN12K4 is a through-hole resistor, which means that it must be mounted securely to the board. It should be handled carefully when being soldered in place, to prevent any damage to the device. The leads should be bent into position and securely soldered in place, and the device should be mounted on the top side of the board to ensure that it is in contact with the circuit traces.

In conclusion, the MFR-25FRFPN12K4 is a through-hole resistor with a nominal value of 12 kilo-ohm (K4) and a tolerance rating of ±2%. This device is used in a wide variety of applications, and is suitable for use in high voltage applications. It should be handled carefully when being soldered in place, and should be mounted to the top side of the board in order to ensure good contact with the circuit traces.
