Inrush Current Limiter MF73T-110/13 High Power NTC Thermistor 10 OHM 20% 13A 30MM For High Power Switching Power Supplies
Inrush Current Limiters are used to reduce the inrush current that occurs when an electrical device is switched on.
High inrush current is the result of the maximum instantaneous input current drawn by an electrical device during the initial power up.
As technology continues to advance, most systems today run efficiently and maintain a low impedance which in turn contributes to high inrush current.
Characteristics
• Small size, high power, reliable surge current protection.
• High material constant (B value),
• Low residual resistance
• High steady state current, long lasting, high reliability
• Convenient for PCB installation, wide operating range
Applications
• High power switching power supplies, Power conversion, UPS power.
• High power battery charger, electric vehicle battery charger.
• High power LED light, high power electronic energy saving lamps and other lamps.
Technical requirements:
1) Zero Power Resistance: R25:10Ω±20%
2) B-value:B25/50: 3200K±10%
3) Tinned copper wire
4) Black silicon resin
5) Meet environmental protection requirements:RoHS
- 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
- Shock resistance,humidity resistance, heat resistance, good heat dissipation
- Fully insulated, suitable for printed circuit boards.
- The wire is wound on he porcelain rod and then the joint is welded to produce accurate resistance value and prolong the service life.
- Resistance is made of metal oxide film (MO) instead of winding.
- Excellent heat resistance, low resistance temperature coefficient, linear change.
-
It can withstand short-term overload, low noise, and the resistance value has not changed over the
years.
-
Good explosion-proof performance for protection
