Kynar Insulated Lead MF52D Black Enameled Wire NTC Thermistor
Temperature Sensor 50K 3950
Description Of The NTC Thermistor Temperature Sensor 50K 3950
Similar to our MF52B Series, AMPFORT’s MF52D series
temperature sensing thermistors are available with a wide range of
resistance values and tolerances ranging from ±1% to ±10% as well
as point matched options. The MF52D thermistors are built with
Kynar insulated lead wire and are capable of withstanding
temperatures up to 135°C. Low cost and highly stable devices make
this sensor an excellent choice for temperature measurement,
control and compensation applications.
