Matsuo Current Fuse KAB M Series

Product overview

Matsuo Current Fuse KAB M Series 720 is designed for circuit protection against excessive current in navigation systems, in-vehicle camera systems interior automotive components and other machinery equipments etc, which is significantly reliable type.

It is qualified for AEC-Q200 that the standard is globally applied by automotive industry. Also, the ecology design of Current Fuse KAB M Series 720 is friendly to environment due to complete lead free.



  • New type fuses were developed by our original technology. They show no variation in fusing characteristics and have excellent fast-blow capability.
  • Surface temperature rise is 75°C or less when applying rated current. This offers less influence on the peripheral units.
  • The fuses come in ultra-small size 1608 (1. 6×0.8×0.45 mm) and 2012 (2. 0×1. 25×0.5 mm).
  • Precise dimensions allows high-density mounting and symmetrical construction of terminals makes possible for automatic mounting and “Self-Alignment” by chip placer.
  • 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.
  • LEAD-FREE and RoHS Compliant.
  • Due to its high reliability, KAB M series 720 are suitable for circuit designs for automotive interiors.
