SR-5F Series Fast-Acting Subminiature Fuses

  

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
