TYPE
KAB
(P-KAB-E003)
Type KAB 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 Type KAB is friendly to environment due to complete lead free.
FEATURES
1. New type fuses were developed by our original technology. They show no variation in fusing characteristics and have excellent
fast-blow capability.
2. Surface temperature rise is 75°C or less when applying rated current. This offers less influence on the peripheral units.
3. The fuses come in ultra-small size 1608 (1.6×0.8×0.45 mm) and 2012 (2.0×1.25×0.5 mm).
4. Suitable for automatic mounting
5. Precise dimensions allows high-density mounting and symmetrical construction of terminals provide “Self-Alignment”.
6. Resistance to soldering heat : Reflow or flow soldering 10 seconds at 260°C
7. High accuracy carrier tape by using pressed pocket paper ensures excellent mounting.
8. LEAD-FREE and RoHS Compliant
