Similar to the BetaCURVE Thermistor Series I, the
Series II thermistors are small epoxy coated devices. The
same quality thermistor elements are used during assembly.
Series II are manufactured using 30 AWG teflon insulated
lead wires. They offer the same choice of precision
temperature tolerance classifications for a wide variety of
customer applications.
The Series II differs from Series I marginally with
respect to D.C. The typical value of 0.85mW/oC in still air
at 25oC is due to the larger lead wire diameter made of pure
The insulated lead wires offer customers the added
protection of TFE teflon insulation that has the highest
temperature rating (150oC) of the most common insulating
materials. TFE teflon is a material that does not bond easily
with epoxies or adhesives. For this reason the surface of the
teflon wire is etched, which enhances bondability for
applications that require mounting or potting the thermistor
with epoxies or adhesives.
The series is produced in high volume as a
Standard configuration. Other configurations are available
on a custom basis. Larger or smaller lead wires can be used
with the same chip elements and with insulating materials of
PVC, Kynar, Tefzel, Nylon/Polyurethane, etc. Contact
Applications Engineering Group for support if requirements
differ from the standard configuration as shown above.
