NTC THERMISTORS: TYPE ND
CHIP THERMISTOR WITH OR WITHOUT WIRES
DESCRIPTION:
A range of resin-coated chips with wires (bare or
insulated) and uncoated, unwired chips with thick
film silver electrodes.
FEATURES:
Designed for accurate temperature measurement,
control & compensation
Tight tolerances on resistance and B value
Operation up to 155°C with excellent stability
Small body size
Fast response
Available with nickel or monel (cupronickel) wires
to limit heat conduction
Epoxy resin provides voltage insulation
Suitable for automotive, HVAC & white goods
applications
