Probably because the operating temperature is about 0 Kelvin.

  I guess it doesn't have to go quite that low, depending on what you make it out of. Though you have got me wondering whether anyone has put a crumb of high temp superconductor in a smd resistor package yet and if so, for what purpose.

    "High temperature" is relative, they still have to be cryogenically cooled to temperatures around -100C. So no SMD superconductors yet.

      That is still a relatively accessible temperature, given that liquid nitrogen is about the same price as clean water. Off the top of my head, I could think of one use, which would be to trigger a transistor to switch on and off some high power superconducting circuit when the small bit of superconductor gets cold enough to start superconducting.
