The applications advantages of fusible resistors


The applications advantages of fusible resistors 

Fusible resistors are used in electrical circuits that may occasionally be exposed to short circuit conditions for a short period of time.  They will blow out like a fuse in the event of a short circuit, protecting the circuit from damage and fire. 
Fusible resistors are used in motor controller systems, automobiles, power supplies, rectifiers and inverters, home appliances, power tools, and other equipment. 
The main benefit of using this resistor is that its resistance function controls inrush current. 
This resistor is used as the main above current component within a charger or a power supply. 
A fusible resistor performs dual functions.  Once the power supply is exceeded, then it works like a resistor limiting current.  Similarly, once the rating of power is exceeded, then it works as a fuse in the circuit to defend different components within the circuit from the surplus current. 
The fusible resistor which is a special kind of resistor used to protect any circuit.  This resistor is very helpful for extremely sensitive circuits which are used for lower power applications where the requirements of surge handling & overload are not too severe.

The advantages of a fusible resistor are discussed below.

One of the key advantages of a fusible resistor is that it allows current to flow through it until a certain maximum value is exceeded, at which point the resistor burns out, preventing damage to other components as a result of an overload.
They are self-limiting, which means they’ll reduce current flow to a safe level if the resistance drops below a certain point. They provide overload protection and do so at an affordable price.
They can be used in both AC and DC circuits. This is particularly beneficial in applications where the power source may vary from AC to DC.
Fusible resistors don’t require monitoring or maintenance—they’re passive components that don’t need any attention at all.
Extremely low inductance.
Excellent high-frequency characteristics, making them a great choice for RF applications.
A wide range of resistance values is available, ranging from 0.1 ohms to two megohms.
Tolerances as tight as 0.05%
High stability.
Good frequency characteristics.
