Description
• Fast-acting, low breaking capacity subminiature fuse
• Plastic cap and base, flammability UL 94V0
• Lead wire with tin-plated copper, diameter 0.6mm
• Protects against harmful overcurrents in primary and
secondary applications
• Small radial-leaded design minmizes board space and
eliminates need for additional mounting components
(BK/PCS holder optional if field replacement is
desirable)
• Designed to UL 248-14
