0.025 MM CONSTRUCTION CHOICE
UEW, PEW or EIW?
Polyester · PEW
Discuss insulation and thermal requirements with your stripping or joining process; direct soldering is not assumed.
Polyesterimide · EIW
Discuss higher thermal-duty requirements and the approved build; confirm processing and testing before substitution.
These are available material directions supplied by Jinwei. No single test report on this site certifies every 0.025 mm variant.
NATURAL & COLOURED OPTIONS
Choose your colour.
Confirm your specification.
Specify the colour together with the wire type, conductor diameter and insulation build.
