Possible uses of a MELF resistor?
The cylindrical construction of MELF
  devices provides an optimal power rating and pulse load
  capability related to the mounting space. Continuous
  development has led to improved long-term stability and
  moisture resistance, and allows high-temperature operation
  to + 175 °C.
  
  This paper explores why this resistor series has become so
  successful, and why there is often no alternative to it today
  in professional applications.
