Matsuo Current Fuse JAH L Series

Product overview

Matsuo Current Fuse JAH L Series is designed for circuit protection against excessive current in portable electronic equipment, electric circuit around battery, etc. because the demand for high capacity batteries is increasing.

Wire material is adopted for fuse element, and the performance against pulse resistance is improved in spite of compact design. Also, the ecology design of Current Fuse JAH L Series is environmentally friendly because of its complete lead-free.



  • Our original terminal construction eliminates Tombstone phenomenon.
  • Our original construction design provides excellent fusing and quick acting characteristics.
  • Especially, performance against pulse resistance is excellent since wire material is used for fuse element.
  • Surface temperature rise is 75°C or less when applying rated current for fusing. This gives little influence to the peripheral units.
  • Small size of 3216 ( 3. 2×1. 6×1. 2mm ).
  • Suitable for automatic mounting.
  • Precise dimensions allows high-density mounting and symmetrical construction of terminals provide “Self-Alignment”.
  • Resistance to soldering heat: Flow soldering 10 seconds at 260°C and Reflow soldering 5 seconds at 250°C respectively.
  • A tape carrier of 8 mm width will be provided as a standard package material.
  • Complete lead-free.
