Product Description
Enameled Precision Resistance Wire 0.03mm Konstantan CuNi44 wire with thin insulation for micro resistor
Product Description
These enameled resistance wires have been broadly used for standard resistors, High /Low Voltage Resistor automobile parts, winding resistors, etc. using the insulation processing best suited for these applications, taking full advantage of the distinctive features of enamel coating.
Furthermore, we will carry out enamel coating insulation of precious metal wire such as silver and platinum wire upon order. Please make use of this production-on-order.
