Product Description
Product Overview
The Coat-insulated Fusing Resistors (RF series) are designed to function as standard resistors under normal conditions and provide rapid circuit protection by quickly fusing during abnormal overload situations. These resistors feature a flame-retardant coating equivalent to UL94 V-0 and comply with EU-RoHS requirements. They are suitable for general use and offer reliable protection against excessive overload. For applications involving automotive, medical, or aerospace equipment, or any situation where failure could lead to personal injury or significant damage, prior contact with the sales representative is mandatory.
