NTC Thermistors Single item NTCDS series (Diode lead type) NTCGF series (Resin DIP cable type) Issue date: October 2011 All specifications are subject to change without notice. Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.(1/3) Conformity to RoHS Directive NTC Thermistors NTCDS Series(Lead Type) NTCGF Series(Resin DIP cable type) FEATURES This series features a glass-sealed construction identical to that of DHDs (Double Heatsink Diodes). They are thus highly reliable and resistant to high relative humidity. Tight tolerances are maintained in resistance vs. temperature characteristics. The application of semiconductor mass production techniques has resulted in considerable size reduction and improved consistency.
