Description
• Time-delay subminiature fuse with low breaking
capacity
• 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 rectangular-leaded design minmizes board
space and eliminates need for additional mounting
components (BK/PCS holder optional if field
replacement is desirable)
• Designed to IEC 60127-3 Sheet 4 (400mA - 4A) and
extension 5A, 6.3A
