Type FWFU Series Fusible Wirewound Fixed Resistors

TE Connectivity Type FWFU resistors withstand power overloads and surges, preventing overheating and reducing fire risk

Image of TE Connectivity Type FWFU Series Fusible Wirewound Fixed Resistors TE Connectivity (TE) fusible wire wound fixed (FWFU) resistors are a special type of resistor that also functions as a safety fuse. They allow current to flow normally but break the circuit when the current exceeds a safe level, protecting electronic devices from damage. These resistors are commonly used in power supplies, chargers, and household appliances to help prevent overheating and short circuits. Unlike traditional fuses, they provide some resistance before they blow, making them useful for controlling inrush current.
