BK/PCC-1-R is a subminiature radial-leaded fast-acting fuse from the PC-Tron series, rated at 1A with a short lead length of 0.100 inches. It is rated for 250V AC and 450V DC, with an AC interrupting capacity of 10kA at 125V and 50A at 250V, and a DC interrupting capacity ranging from 300A minimum to 5900A maximum. The fuse is UL Recognized (E19180) and CSA certified (42731), board washable, and RoHS compliant per 2002/95/EC. It operates with a minimum opening time of 4 hours at 100% of rated current and a maximum opening time of 10 seconds at 200% of rated current. This fuse is ideal for high-voltage DC applications requiring individual component or internal circuit protection, with optional mounting socket availability and suitability dependent on application-specific time constants and capacitance values.
