15W High Power Aluminum Housed Wirewound LED Load Resistors,Surface Mount
Structure :
1.The resistors core components are made of insulating and
high-temperature resistant materials as the resistors
framework,evenly wound with high-quality alloy wires.Metal aluminum
shell potted with high insulation non-combustible electronic
paste,so that the aluminum shell and the resistance core components
are closely combined into a solid entity,not affected by external
air,vibration and dust,high stability and thermal conductivity.
2.The aluminum shell is made of high-quality industrial 6063
aluminum,and the surface is high-temperature anodized to achieve
attractive appearance and great heat dissipation.
Features
1.Attractive appearance & easy installation.
2.High stability,impact resistance,good reliability & high
consistency.
3.Ends outgoing:metal terminals or bolted connection.
4.Inductive or Non-inductive available.
5. 25W ~ 50W used in automotive LED lamp industry; 50W, 100W & 250W
used in medium frequency furnace industry.
6.Used for
loading,braking,pulse,charging,discharging,starting,buffering,
discharging,ect.
