Description
The MF72 series Power NTC Thermistors provide inrush current suppression for sensitive electronics. Connecting a MF72 in series with the power source will limit the current surges typically created at turn on. Once the circuit is energized the resistance of the MF72 will decrease rapidly to a very low value, power consumption can be ignored and there will be no effect on normal operating current. Using the MF72 Power NTC Thermistor is a most cost-effective way to curb surge current and protect sensitive electronics from damage.
Application
Can be installed into the power circuits of:
• Power supplies and inverters
• Uninterruptible Power Supplies
• Energy saving lamps
• Electronic Ballasts
• Filament Protection of various types of lamps
• Some types of heaters
• For higher power circuits ask about the MF73 and MF74 series surge suppressors.
Characteristics
• Small Size and fast response
• High Power handling capability
• Fast response to surge current
• High material constant (B value)
• Low residual resistance
• Wide operating temperature range -55 to +200C
• R25 allowable tolerance is ±20%
• Long-term Stability and Reliability
