Through Hole Resistors (THRs) are among the most common electrical components. They are used in a wide range of applications, ranging from power electronics to consumer electronics. The MFR-25FRF52-1M21 is a THR that is particularly suited to high power applications.
The MFR-25FRF52-1M21 THR is an extremely durable component designed to resist high temperatures and voltage spikes. This makes it ideal for use in power systems such as switchgear, HVAC systems, and other systems which require reliable protection from surges. The MFR-25FRF52-1M21 is also suitable for use in consumer electronics applications, such as for the control of motors or the functioning of solenoids. It is even suitable for use in safety-critical medical applications.
The MFR-25FRF52-1M21 THR has a power rating of up to 1 megawatt, and it is rated for operations of up to 400V AC. It is also rated for an insulation resistance of up to 200 megohms, a current capacity of up to 3.5 amps, and an average life expectancy of up to 5,000 hours.
The MFR-25FRF52-1M21 THR is a through-hole device, meaning that it can be mounted directly on a circuit board with no need for additional support. This eliminates the need for costly inductors, capacitors, or other components that may be associated with integrated solutions. The MFR-25FRF52-1M21 also has broad stable electrical characteristics across a broad range of workloads, making it an ideal choice for a variety of applications.
The working principle of the MFR-25FRF52-1M21 THR is fairly simple. It operates on the principle of two resistors, one in series and one in parallel. With a voltage applied across the device, the resistors in series create a voltage drop (V drop) across the device. This voltage drop determines the amount of current flowing through the remainder of the circuit. The resistor in parallel creates an additional amount of voltage drop (V drop) across the device. This also influences the amount of current flowing through the remainder of the circuit.
The MFR-25FRF52-1M21 THR thus has a wide range of applications, ranging from power electronics and consumer electronics to medical and safety-critical applications. Its durable construction and stable electrical characteristics make it an ideal choice for applications requiring fail-safe protection from voltage surges, and its through-hole design eliminates the need for additional energy-consuming components.
