M Series Thermistor Configuration:
Part Number Code:
M Series NTC Thermistor:
Applications:
¥ Temperature sensing and control.
¥ Temperature compensation.
¥ Temperature measurement.
¥ Automotive Applications.
Features:
¥ Low cost.
¥ High stability.
¥ Available on tape and reel or bulk.
¥ 25/85 Beta Value tolerance = +/-3%
¥ High dissipation Constant (min 4.5mW/oC).
The range of M Series Thermistors are
commonly used as a temperature compensation device
because of low cost. This high quality, stable thermistor
can be employed for temperature control sensing
between -30oC and 125oC. The complete series is
available on tape and reel suitable for automatic
assembly.
