Description:
5TR Slow Blow Micro Fuse is in radial leaded and time-lag thru-hole ,it is international
accepted for primary and secondary overcurrent protection since
designed to IEC 60127-3,Sheet 4 and can mount into PCB or plug into
BK / PCS holder directly, also along with high inrush withstand
capability. It is used to control the current to protect the circuit.Once the
current in the circuit is higher than the rated current of the
appliance, the fuse will automatically cut off the current to
protect the safety of the appliance. 5TR Micro Fuse protect the
circuit by fusing themselves by the joule heat of the current
flowing through the fusible metal. Most electrical appliances have
fuses. 5TR Micro Fuse has the characteristics of small size, high
sensitivity and quick protection. 5TR slow blow micro fuse is widely used in power supplies, computer
power supplies, adapters, switching power supplies, chargers, LED
lighting power supplies, communications products, telephones, home
appliances, various types of equipment, and small home appliances
and electronic products. It is a variety of electrical products
indispensable security element.
