Soderex®/155 - Superior Essex

Essex ® SODEREX ® / 155Magnet Wire / Winding WireNEMA MW 79-CClass 155 - Copper - Round Conductors - Polyurethane coated magnet wire / winding wire.APPLICATIONSoderex ® /155 magnet wire is used when a coil orcomponent design needs to utilize the uniquesolder stripping property of the polyurethane resinconstruction.Soderex ® /155 magnet wire, with its modified polyurethanefilm, has in the past several years become thestandard Class 155 wire for a wide array of fine wirecoil applications.Soderex ® /155 magnet wire is recommended but notlimited to the following applications:• Small motors, armatures, and fields• Appliance controls and relays• Automotive controls and relays• Solenoids• Bobbin wound coils• Electronic coils• Small transformers• Linear motors• Instruments• RF coilsENGINEERING HIGHLIGHTS1. THERMAL CLASSIFICATIONSoderex ® /155 magnet wire is Class 155 when measured inaccordance with the ASTM D 2307 test method. Heat shockresistance meets 175°C.2. THERMOPLASTIC FLOWThermoplastic flow (cut-thru) temperature of Soderex ® /155magnet wire is in the 220°C plus range; well above maximumprocess conditions found in most molded coil work, trickleimpregnation processes and standard pre-heat varnishcycles specified for normal Class 155 systems.3. SOLDERABILITYSoderex ® /155 magnet wire solder strips readily andmuch more easily than MW 77 type products. It soldersconsistently at temperatures as low as 390°C.4. WINDABILITYFlexibility and adhesion properties of the Soderex ® /155magnet wire film are more than adequate for all but the mostsevere fine wire winding applications.5. ELECTRICALSoderex ® /155 magnet wire insulation exhibits high dielectricstrength retention under high humidity conditions. Thelow dissipation factor of Soderex ® /155 magnet wire athigh frequencies makes it a prime candidate for RF coilapplications.6. CHEMICALThe solvent resistance properties of Soderex ® /155 aresuitable for most Class 105, 130, and 155 varnishes,encapsulation materials, and treating resins.7. NORMAL AVAILABILITY• Round Copper Sizes:28-47 AWG, Single and Heavy BuildPlease consult Magnet Wire Marketing for additionalsize (including metric) and build information.
