Product Description:
MF72 series is designed in circuit to avoid the surge over current occurred at the instant circuits turned on. The device can effectively suppress the surge current, and its resistance and power consumption will be reduced greatly when circuit work in normal condition.
Typical Applications:
1. Protection of the power circuits of conversion power supply.
- switching power supply.
- UPS power supply.
2. electric heaters.
3. electronic energy-saving lamps.
4. electronic ballasts and so on.
Features:
1. Strong power and strong capability of surge current protection.
2. Fast response to the rapidly surge.
3. Big material constant (B value).
4. Small remain resistance.
