The RF16-185F is an over-temperature protection (OTP) blanking device manufactured by AUPO. It features a 1.85 amp Polymer Positive Temperature Coefficient (PTC) fuse, which is designed to limit the temperature in normal operation and protect against excessive temperatures. The RF16-185F is UL recognised, RoHS Compliant, and is rated for a DC voltage of 125/250 VAC. The maximum operating current is 1.85A and the operating temperature is -20°C to 85°C. In the event of a fault, the PTC device melts the internal fuse and eliminates fire hazards associated with traditional fuses. The RF16-185F is a widely used OTP blanking device for use in power supplies, universal motors, industrial motors, and other consumer and communication products.
