RX20 100W 50ohm 100 Ohm Porcelain Tube Adjustable Resistor Suitable For Loading Braking
Features:
1.Strong overload capacity
2.good heat dissipation, long life, high precision
3.The resistors surface is coated in green
Customization service: Please tell me the power and resistance value you need to customize.
Excellent heat dissipation performance: the porcelain tube is used as the winding matrix, the porcelain tube has high heat dissipation, and then packaged with nano organic silicon coating and other environmental protection materials, which can effectively dissipate the heat generated by the resistance, reduce the surface temperature rise of the resistance body, ensure the stability of the resistor in the long time working process, and greatly improve its load resistance and service life.
High stability and reliability: High-stability resistance wire is selected and wound in accordance with scientific engineering standards and rigorous process methods, making the resistance have strong impact resistance. Meanwhile, the non-combustible paint encapsulation effectively protects the resistance wire, further extending its service life and ensuring stable and reliable operation even in complex working environments.
Strong customizability: It can be customized according to different customer needs, such as adjustment methods, terminal block designs, etc. For instance, some products can be equipped with two or more terminal blocks with good electrical conductivity to facilitate connection with circuits. Products that meet specific requirements can also be designed and manufactured according to customer demands
