Anti-Surge Fixed Resistors
Featured with high working voltage and high stability, with flame retarding coating(UL94V-0), our anti-surge fixed resistors can work in humidity and high temperature conditions.
Product Description
Anti-Surge Fixed Resistors
Anti-surge fixed resistors are specially designed to withstand high levels of inrush current, which can occur during power surges or when switching on a device. When these resistors are exposed to a sudden surge of current, they can generate a significant amount of heat and can even burn out if not designed to handle such situations. Anti-surge resistors are constructed to have a higher power rating and can handle a larger amount of current than standard resistors, making them ideal for use in circuits where high surge currents may occur.
Anti-surge fixed resistors are typically made of carbon or metal oxide films and are available in a range of resistance values and power ratings. They are often used in power supplies, motor controls, and other applications where high surge currents are likely to occur. When selecting an anti-surge fixed resistor, it is important to ensure that the resistor is rated for the appropriate power and current handling requirements of the circuit it will be used in.
