Matsuo Current Fuse KAH

Product overview

Matsuo Current Fuse KAH  micro fuse is designed for circuit protection against excessive current in portable electronic equipment, electronic circuit around battery, etc. because the demand for high capacity batteries is increasing.

Further miniaturization and low profile with extended rated range can be used for wider application. Also, the ecology design of Current Fuse KAH Type is friendly to environment due to complete lead free.



  • 5-face terminals structure ensure superior performance of shear strength (10 N for 5-face terminals, 5 N for conventional type).
  • With new development of micro fuse using our original production method, Type KAH, size 1005 can ensure same fusing characteristics of size 1608 of our Type KAH.
  • Complete lead-free Type KAH is designed to eco-friendly.
  • UL file number E170721. (UL248-1 & 14).
  • Surface temperature rise is 75°C or less when applying rated current. This offers less influence on the peripheral units.
  • 1005 is the Ultra-small size. (1. 0 x 0.5 x 0.35 mm).
  • Suitable for automatic mounting.
  • Precise dimensions allows high-density mounting and symmetrical construction of terminals provide “Self-Alignment”.
  • Resistance to soldering heat : Reflow or flow soldering 10 seconds at 260°C.
  • High accuracy carrier tape by using pressed pocket paper ensures excellent mounting.
