{"title":"0.4mm Heat Resistant Welding Wire (Black)","handle":"0-4mm-heat-resistant-welding-wire-black","url":"/products/0-4mm-heat-resistant-welding-wire-black","description":"This 0.4 mm heat-resistant welding wire is built from seven 0.08 mm silver-plated copper conductors with a PFA insulation jacket. It handles temperatures from −60 °C to +250 °C, making it suitable for fine soldering work, rework, and environments where standard wire insulation would degrade.\n\nAt just 0.4 mm outer diameter, this wire is thin enough for circuit board fly-wiring, jumper connections, and wearable electronics where space is extremely limited. Supplied on a 50 m roll in black.\n\nKey Features\n\n\nSilver-Plated Copper Conductor – Seven 0.08 mm strands for excellent conductivity and flexibility\n\nPFA Insulation – Heat, moisture, and corrosion resistant\n\nWide Temperature Range – Rated from −60 °C to +250 °C\n\nUltra-Thin 0.4 mm OD – Ideal for fine-pitch and space-constrained wiring\n\n50 m Roll – Generous length for multiple projects\n\n\nSpecifications\n\n\nOuter Diameter: 0.4 mm\n\nConductor: 7× 0.08 mm silver-plated copper\n\nInsulation: PFA\n\nTemperature Range: −60 °C to +250 °C\n\nColour: Black\n\nLength: 50 m per roll\n\n\nIdeal For\n\nCircuit board fly-wiring and jumper connections\nPCB rework and repair\nWearable electronics\nHigh-temperature soldering environments\n\n\nPackage Contents\n\n1× 0.4 mm Heat Resistant Welding Wire, Black (50 m roll)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2730,"title":"Default Title","sku":"DF-FIT0751","price":17.14,"on_sale":false,"in_stock":true,"available_quantity":11,"option1":"Default Title"}]}
