Model Description

MF58-103F 3950

  • MF58: Glass-encapsulated temperature measuring NTC thermistor
  • 103: Zero-power resistance at 25 is 10K
  • F: Resistance tolerance code (F-1%, G-2%, H-3%, J-5%)
  • 3950: B25/50 value is 3950K

Usage Precautions

  • Purpose: Temperature measurement and control.
  • Avoid current flow through the thermistor chip causing self-heating and measurement errors.
  • When soldering with a soldering iron, the welding point should be at least 2mm away from the glass bead, with a soldering temperature below 360 and a welding time less than 3 seconds.
  • If the lead wire is bent, the bending point should be more than 2mm away from the glass bead to prevent damage.
  • Storage Temperature: -1040.
  • Storage Humidity: 75% RH.
  • Avoid storage in environments with corrosive gases and direct sunlight.
  • Reseal packaging after opening.
