NEC SF Series fuses with their unique electrical properties, thermal stability and mechanical strength, play a crucial role in the circuit. Understanding the key components of the NEC fuse SF series and its role will help us to better understand its working principle and performance.
NEC SF10A, 15A fuse by the fuse, plastic shell and two ends of the fuse is the core part of the fuse, made of low melting point alloy, can be quickly fused in the case of over current, so as to cut off the circuit, protect the circuit board and components, the plastic shell plays the role of insulation, voltage resistance and protect the fuse. The two end leads are connected to the circuit to transmit the current.
The fuse body is the core part of NEC plastic fuse, which is made of low melting point alloy, and can quickly fuse in the case of over-current, which is related to the safety ability of the protection circuit, the plastic shell, as an insulator, can prevent current reflux, and protect the fuse body from the influence of external mechanical forces. Commonly used plastic shell materials are PC, PA, etc., with high insulation performance and heat resistance, both ends of the lead is NEC plastic fuse and circuit connecting the bridge, material for copper wire or aluminum wire. The conductivity and mechanical strength of the lead wire have an important influence on the performance and stability of the fuse.
NEC SF Series fuse assembly and maintenance
When assembling the NEC plastic fuse SF10A15A, note the following points:
Check whether the mounting hole position on the circuit board matches the external size of NEC plastic fuse SF10A15A. During installation, the fuse body, plastic case and the lead shell of NEC plastic fuse SF10A15A have close connection and good contact to avoid loosening or falling off. When connecting the line, ensure that the input and output leads are properly connected to the input and output terminals of the NEC plastic fuse SF10A15A and are fixed and welded with appropriate tools.
For the maintenance of NEC plastic fuse SF10A15A, the following points are noteworthy, regularly check the status of NEC plastic fuse SF10A15A, including appearance, fixation condition, electrical performance, etc., to ensure its normal operation. When the NEC plastic fuse SF10A15A is fused, the new fuse should be replaced in time. Before replacement, the cause of the circuit breaker should be identified and troubleshooting, so as to avoid the same problem again. In the process of use, attention should be paid to avoid the NEC plastic fuse SF10A15A by too large mechanical external force or vibration, so as not to cause mechanical damage or electrical failure. Take care to protect the NEC plastic fuse SF10A15A or interference or damage from other lines or components.
