The main function of the MF72 series power NTC thermistor is to provide surge current suppression for sensitive electronics. Connecting the MF72 in series with the power supply will limit the current surge that is usually created when turning on. Once the circuit is powered on, the MF72 power NTC thermistor will quickly drop to a very low value, the power dissipation can be ignored and will not affect the normal operating current. Using the MF72 power NTC thermistor is one of the most cost-effective ways to suppress surge current and protect sensitive electronics from damage.
Applications:
• Can be installed in power circuits of:
• Power supplies and inverters
• Uninterruptible power supplies
• Energy-saving lamps
• Electronic ballasts
• Filament protection for various lamps
• Some types of heaters
• For higher power circuits compared to MF73 high power NTC thermistor
Product Features:
• Small size and fast response
• High power handling capability and long-term stability and reliability
• Fast response to surge current
• High material constant (B value)
• Low residual resistance
• Wide operating temperature range -55 to + 200C
• R25 tolerance of ±20%
