Standard tolerance thermistors A range of 13 negative temperature coefficient bead thermistors and 4 disc thermistors constructed from a compound of nickel manganite. Of the 13 bead thermistors, ten types are sealed in glass and three are incorporated into stainless steel probe assemblies. This range was designed primarily for temperature measurement and control, flow measurement and liquid level detection. The four NTC disc thermistors are intended for use in temperature compensation, measurement and control applications. Disc diameter in all cases is 10mm with a lead pitch of 5mm (nominal). The range of DO-35 packaged NTC thermistors is designed for temperature measurement and control in applications which demand cost effective reliability. Typical applications include domestic appliances, automotive systems, data processing equipment and heating/ventilating/air conditioning control. The hermetically-sealed construction combines the advantages of high temperature operation and high reliability of glass bead types with the closer tolerances associated with chip devices. The glass encapsulation offers the additional benefit of high voltage insulation.
