EXAR® 155 SFX-OR (Non-UL)
EXAR® 155 SFX-OR is the superior heat-defying cable in its class. Its irradiation cross-linked polymeric insulation possesses remarkable mechanical, flame resistance and electrical properties. It is compatible with many types of magnet wire and varnishes at bake temperatures up to 280°C. Exar 155 processes extremely well on the latest high speed cut and strip machines. Processing costs are reduced by avoiding problems such as solder iron shrink-back, insulation creeping and poor abrasion resistance. Cost effective option in countries and applications where UL/CSA is not required.
