Product Description
Product Overview
The Fusing Resistor RF series, also known as Coat-insulated Fusing Resistors, are designed to function as standard resistors under normal conditions while providing rapid circuit protection through quick 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 resistor applications and are specifically recommended for use in automotive, medical, and aerospace equipment, where failure could lead to severe consequences. Contact the manufacturer before using in such critical applications.
