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.

This part of IEC 6051 2 is intended to be used as a basis for tests and measurements specifications for electrical connectors. It provides guidance and reference for tests and measurements within the IEC 6051 2 series. It includes the description and the practice of the various phases of tests and measurements (preparation, tests and

This part of IEC 60384 applies to fixed aluminium electrolytic capacitors with conductive polymer solid electrolyte primarily intended for d.c. applications for use in electronic equipment. Fixed aluminium electrolytic capacitors with solid (MnO 2 ) electrolyte are covered by IEC 60384-4. Fixed aluminium electrolytic surface mount capacitors with conductive polymer solid electrolyte are covered by

This part of IEC 60384 specifies preferred ratings and characteristics,selects from IEC 60384-1 :201 6 the appropriate quality assessment procedures,tests and measuring methods,and gives general performance requirements for this type of capacitor.Test severities and requirements specified in detail specifications referring to this sectional specification are of an equal or higher performance level.Lower performance levels are
