AUPO RF30-800F with Fuse: PTC polymer; 8A is a high-reliability circuit protection device designed for use in information and communication systems. The PTC (positive temperature coefficient) polymer fuse is designed to provide overcurrent protection to radio frequency (RF) systems. It features a polymeric-solution embedded PTC element and a silver-oxide fuse element for a combined time-delay and overcurrent protection. It has a rated operating voltage of up to 800V, a rated current of 8A, a 20x rated short-circuit current capacity of over 5000A, and a response time of less than 10 seconds. The PTC element is rated up to 125°C while the silver-oxide fuse element is rated up to 105°C. This product is also UL Recognized, is 360° rotating and is RoHS compliant.
