These thermistors are employed in various applications, including HVAC, automation, battery management systems, automotive and medical equipment, appliances, and electronics.

“Littelfuse has a strong track record of developing custom NTC thermistors for global end markets and applications,” stated Michel Ramirez, Littelfuse industrial business product manager. “To help meet demand, we are creating these series of thermistors to provide customers with a portfolio of accurate, stable, and reliable off-the-shelf products that include a large, easy-to-select inventory with quick quoting and fast delivery times.”

The new series includes:

Glass-Encapsulated NTC Thermistor NGD Series – provides hermetically sealed chips for long-term reliability, stability, and fast response time, even under severe environmental or thermal conditions. Uniform dimensions and axial configuration are particularly suited for use with automatic insertion equipment.

Ring Lug Surface Temperature Sensing NTC Thermistor Probe Assembly NPRL Series – is potted into a ring lug housing with thermally conductive epoxy for exceptional stability. Various mounting stud-hole sizes and lead wire materials and terminations accommodate screw-in-place applications.

Straight Stainless-Steel NTC Thermistor Probe NPSS Series – includes a wide assortment of standard probe housings (less than 1mm to over 9mm in diameter) with various lengths and a large selection of lead wire materials and terminations for application flexibility.

MELF Style Glass-Encapsulated NTC Thermistor NSS Series – has hermetically sealed chips in a glass package for outstanding stability. It has two terminals bonded into a cylindrical body for an extremely reliable surface-mount package that can withstand severe environmental conditions.

Surface-mount End-banded NTC Thermistor NSRA, NSRB, NSKR and NSLR Series – include a solder-coated metallisation suitable for various contact techniques, including wire bond, epoxy, or solder. They have extremely uniform parameters for use with automatic handling and placement equipment and come in various sizes.

Miniature Leaded Epoxy-coated NTC Thermistor NXK Series – provides Kynar-insulated epoxy-encapsulated lead wires for optimal performance. With superior, long-term reliability, these thermistors are ideal for temperature measurement, control, and compensation applications where cost optimisation is a primary consideration.

Leaded Epoxy-coated, Uninsulated NTC Thermistor NXU Series – is epoxy-encapsulated for optimum performance and supplies precision accuracy with a fast thermal response time. It is excellent for temperature measurement, control and compensation applications.
