Product Model Description:

MF58-104F3950

  • MF58: Glass encapsulated temperature sensing type NTC thermistor
  • 104: 25 zero-power resistance value of 100K
  • F: Resistance tolerance code (F-1%)
  • 3950: B25/50 value of 3950K

Usage Precautions:

  • Purpose: Temperature measurement and control.
  • Avoid self-heating due to current flow through the thermistor chip, which can cause measurement errors.
  • When soldering with an iron, the soldering point should be at least 2mm away from the glass end. Soldering temperature should be below 360, and soldering time less than 3 seconds.
  • If leads are bent, the bending point should be more than 2mm away from the glass end to prevent glass damage.
  • Storage temperature: -10 to 40; Storage humidity: 75% RH.
  • Avoid storage in environments with corrosive gases and direct sunlight.
  • Reseal packaging after opening.
