Ametherm SURGE-GARD™ Inrush Current Limiters
Ametherm SURGE-GARD™ Inrush Current Limiting devices are manufactured using specially formulated metal oxide ceramic materials. SURGE-GARD devices are capable of suppressing high inrush current surges. These Ametherm inrush current limiters are especially useful in power supplies where the low impedance of the charging capacitor exposes the diode bridge rectifier to an excessively high current surge at turn-on.

- Features tolerances down to 15%
- Offers diameters from 10mm to 32mm
Applications
- Switching power supplies
- AC motors
- Motor drives
- Audio amplifiers
- Battery chargers
