MF58 Transistor NTC Thermistor

　　NTC thermistors are made of specially configured metal oxide ceramic materials, which can be used to suppress high inrush currents. Compared with the protected circuit, the thermistor has a higher resistance; therefore, the inrush current is suppressed for about 1 to 2 seconds, during which time the resistance of the thermistor will decrease due to the increase in temperature, until the thermistor is two The terminal voltage drops to a negligible resistance value. The MF58 transistor is a kind of NTC thermistor.

　　The MF58 transistor NTC thermistor is housed in a glass encapsulated, diode DO35 profile with axially tinned Dumet (copper-clad nickel-iron) wire. Widely used in temperature measurement, detection, indication, monitoring, metering, control, calibration and compensation, etc.

　　Features:

　　• The glass body DO35 package provides hermetic sealing and voltage isolation for operation in high temperature and humidity environments.

　　• Small size, sturdy and easy to install automatically.

　　• Fast induction, high sensitivity.

　　• Operating temperature -45°C to +250°C.

　　• The nominal resistance at 25°C can be 2kΩ-1000k ohms.

　　• Typical resistance at 25℃ 2k, 5k, 10k, 20k, 47k, 50k ohm, 100k ohm, 200k, 500k, 1000k, etc.

　　• Tight tolerances for resistance and B values.

　　• Dissipation factor: ≥2.0mW/C.

　　• Thermal time constant: ≤12 seconds in still air.
