Directly heated negative temperature coefficient thermistors - Part 2: Sectional specification - Surface mount negative temperature coefficient thermistors (IEC 60539-2:2003 + A1:2010); German version EN 60539-2:2004 + A1:2010
Direkt geheizte temperaturabhängige Widerstände mit negativem Temperaturkoeffizienten - Teil 2: Rahmenspezifikation - Oberflächenmontierbare temperaturabhängige Widerstände mit negativem Temperaturkoeffizienten (IEC 60539-2:2003 + A1:2010); Deutsche Fassung EN 60539-2:2004 + A1:2010
Overview
This part of IEC 60539 applies to directly heated surface mounted negative temperature coefficient thermistors which are usually manufactured from transition metal oxide materials with semi-conductive properties. These thermistors have metallized terminal faces or solder strips and are intended for direct mounting on substrates of hybrid integrated circuits or printed-circuit boards. The responsible Committee is K 614 "Temperatur- und spannungsabhängige Widerstände" ("Temperature- and voltage-dependent resistors") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
