THERMISTORS
-
Description
A range of NTC (Negative Temperature
Coefficient) miniature disc thermistors,
for general purpose applications such as
temperature measurement and thermal
compensation circuits. Also useful in the
classroom for demonstrating how the
resistance changes with temperature. A
thermistor is a temperature dependant resistor
or ‘thermal resistor’. The thermistors are clearly
coded and have a wide working temperature
range of –30°C to +125°C and a tolerance of
10%. Resistance Approx. resistance Max. current
