Ⅲ.Main characteristics

Effective Inrush Suppression:Features 20 Ohms resistance at 25°C,which can quickly limit the inrush current when the device is powered on,avoiding damage to circuit components caused by instantaneous large current.

Low Steady-State Resistance:Resistance at working current is only 180 mOhms, which reduces power loss during steady-state operation and improves the energy efficiency of the whole circuit system.

High Steady-State Current:Maximum steady-state current reaches 10 A, capable of bearing large working current,meeting the demand of high-power electronic device applications.

Stable Resistance Tolerance:Resistance tolerance is ±25%,with stable electrical parameters and good consistency,ensuring reliable inrush current limiting performance in different working environments.

Standard Series Design: Belongs to Vishay Ametherm’s MegaSurge™ series, adopting mature production technology,with strong product reliability and long service life.

Reasonable Structural Design:Diameter of 31.00mm and lead spacing of 7.80mm, with reasonable size and spacing, easy to install on circuit boards and convenient for welding operation.

 

Ⅳ.Application field

Power Supplies:Installed in the input circuit of industrial power supplies to limit the inrush current when the power supply is turned on, protecting the power supply’s rectifier bridge and filter capacitor from damage.

Household Refrigerators:Used in the power input circuit of household refrigerators to suppress the inrush current when the compressor starts, protecting the refrigerator’s control panel and compressor motor.

Industrial Inverters:Used in the input terminal of small industrial inverters to suppress inrush current during power-on, protecting the inverter’s internal power components and ensuring stable operation.

Uninterruptible Power Supplies:Installed in the power input circuit of UPS devices to limit the inrush current when switching to backup power, protecting the UPS’s battery and power conversion module.

Electric Water Heaters:Applied in the power circuit of electric water heaters to suppress the inrush current when powered on,protecting the water heater’s heating tube and temperature control module.
