Matsuo Current Fuse JHB

Product overview

Matsuo Current Fuse JHB is designed for the purpose of external short circuit protection of the lithium ion battery of medium sizes, such as a power tool and an electric assistant bicycle.

Though it was a surface mount type, it was small and realized high current rating, because a fuse element and a terminal adopt the structure of one.

Furthermore perfectly compliant to Lead-free makes environment friendly design.

*Please beware of imitations.



  • High current rating was realized because a fuse element and a terminal adopt the structure of one.
  • Surface mount type and small size of 7358 (7. 3 × 5. 8 × 4. 2mm).
  • Surface temperature rise is 75°C or less when applying rated current . This gives little influence to the peripheral units.
  • Alumina ceramics are adopted as a case, original structure is adopted as the inside of a case, and the safety at the time of fusing is improved. [Application classification by use: 4 ]
  • Suitable for automatic mounting.
  • Complete lead-free.
