BS EN 60539-2:2004 Directly heated negative temperature coefficient thermistors - Sectional specification - Surface mount negative temperature coefficient thermistors
This part of IEC 60539 is applicable to surface mount directly heated negative temperature coefficient thermistors, typically made from transition metal oxide materials with semiconducting properties. These thermistors have metallized connecting pads or soldering strips and are intended to be mounted directly on to substrates for hybrid circuits or on to printed boards.
