N T C Te m p e r a t u r e M e a s u r e m e n t S e n s o r s March 2016 NTC Thermistors Element NTCDS・NTCGF series NTCDS Glass-encapsulated NTC thermistors NTCGF Resin coated NTC thermistors (2/6) S E N S O R S NTC Thermistors Product compatible with RoHS directive Halogen-free Compatible with lead-free solders Element Overview of the NTCDS・NTCGF Series 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.
