Wirewound Fuse Resistor
Product Description
A wirewound fuse resistor is a type of resistor designed to act as both a resistor and a fuse. This component is often used in electronic circuits to limit current flow and provide overcurrent protection. The Wire Wound Resistors construction involves winding a resistive wire around a ceramic or fiberglass core.
1. Good heat-durability,low temperature coefficient,low noise,high load and power,nonflammability
2. Can be Fusible during the stated time for protecting the circuit.once wording at the required overload voltage.
3. Operating ambient temperature:-55℃~+275℃
4. The surface is gray white nonflammable coating and indicate a black ring at the behind of the precision color ring
5. Resistance tolerance:+5%，+10%
