Product Overview
Over-temperature protected fusible wire-wound resistors are high-reliability resistors that integrate overcurrent protection and over-temperature fusing functions. This series employs a dedicated thermal fusing design, which can quickly disconnect the circuit in the event of overload or abnormal temperature rise, effectively preventing damage to the power supply or charger.
The products possess excellent surge withstand capability (up to 2KV, compliant with IEC 61000-4-5 standard), maintaining stable operation even under transient high-voltage surges. They are also UL1412 certified, ensuring safety and consistency, and are particularly suitable for charger soft short-circuit protection and circuit board over-temperature protection applications.
