Description

25W High Power Aluminium Cased 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.RH&NH Aluminum Resistor is also called metal aluminum resistor,non-induction aluminum resistor,golden aluminum resistor,LED aluminum Resistor,etc. according to different applications and customs.Aluminum alloy shell with grooves on the surface for better dissipation.
2.Owning small size,high power rating,resistance to high temperature and high over load,high precision,high stability,strong construction,favorable mechanical protection,easy installation,etc.
3.RH&NH aluminum resistor is also the best alternative for current sense resistor,standard low-induction resistor and untra precision resistor.
4.Used for loading,braking,pulse,charging,discharging,starting,buffering, discharging,ect.
