SR-5F Series Fast-Acting Subminiature Fuses - 伊顿EATON Bussmann series产品资料中心

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
