400W Wiring Harness Planar Thick Film, Non-inductive High-power Resistor

The lead-out terminals employ extended high-voltage-resistant insulated wires, significantly enhancing the creepage distance and spatial distance between the lead-out terminals, the baseplate, the resistor mounting terminals, and among the lead-out terminals themselves. It is applied in the fields of electrical equipment such as power generation, electric power transmission, and variable-speed drives.

● Filled with special resin material and utilizing high-voltage-resistant insulated wires for the lead-out terminals, the overall creepage distance and spatial distance of the resistor are enhanced.
● Professional design ensures low inductance and capacitance values.
● Special resistor material guarantees the stability of the resistor under high-power and pulsed usage conditions.
● Fixed installation with M4 screws ensures that the attachment pressure on the heatsink is maintained between 120-160 Newtons.
● The raw materials have passed UL94-V0 certification.
