Murata Code PTFM04BB471Q2N34BS POSISTOR Cross, Screw Clamp PTC Overheating Sensing Protection Lug Terminal Type 120C 470 Ohm.

AMWEI Ordering Code: AMZ6-101RT120B

Screw Clamp PTC Metal Lug Tag Terminal Probe Features

  • Screw clamp type temperature sensor, for sensing the temperature
    of transistors, thyristors, stereo main amplifiers, and
    other devices having risk of overheat.
  • Limit temperature sensor with epoxy resin coating.
  • Tinned pin leads wire.
  • Metal lug tag screw clamp type easy mounting.
  • Metal tag lug permits good thermal coupling and
    thus short response time.
