## **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

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
