    Product features:
  • EXAR 150 SFX
  • Oil Resistant
  • UL3271 -UL3289

EXAR® Oil Resistant SFX is the superior flexible and heat-defying cable in its class. This innovative new irradiation cross-linked polyolefin insulation combines the oil resistance of EXAR 150 with the flexibility and rubber-like feel of SFX.  You can count on the same thermal, size, toughness and varnish release advantages of the original SFX, plus a UL approval for use in oil up to 60°C. SFX can now be the one lead wire you use for multiple applications and environments.  EXAR® SFX is the ultimate lead wire value in the motor and transformer market.
