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 copper.
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.
