Description
NTC Type AB6 thermistor assemblies consist of small GC (chip-in-glass) or Thermobeads that are welded to insulated extension leads. The Thermobeads or GC (chip-in-glass) are hermetically sealed in glass and have fine diameter 0.0007 in to 0.004 in (0.01778 mm to 0.1016 mm) platinum alloy leads. The platinum leads are cut short and welded to insulated extension leads and the joints are covered in one of several insulation types, depending upon the application or environment. The assembly is then ready for insertion into hypodermic needles, catheters or other small housings that require extended leads. Any of the Thermobeads or GC (chip-in-glass) listed in Table I may be used in a NTC Type AB6 assembly. Please consult the data shown for specific electrical or mechanical properties for the thermistor selected.

APPLICATIONs
   Thermobead and GC (chip-in-glass) assemblies are used where the small thermistor must be further connected to longer leads, for insertion into deep wells and cavities, or threading into long tubes. They may also be used, as is, for applications that require fast response measure-ments in confined spaces. With these assemblies, the fast response of the small thermistor is available without sacrificing ease of insertion. The added leads and insulation allow the minute assemblies to be handled in further assembly operations, such as insertion into catheter lumens. The same electrical characteristics that apply to the selected thermistor (resistance value, resistance ratio, stability) are unaltered in the assembly.
