Applications

  • Exempt

The AS32 1R036 inrush current limiting thermistor from Ametherm offers a maximum steady state current of 36A (up to +25°C) and a resistance of 1Ω ±25% (at 25°C). The Ametherm AS series are designed to withstand high steady-state current and input energy. Compared to traditional inrush current limiters, the devices offer lower current density, faster reset times, and a wider temperature range without derating. This lower current density, in combination with a uniform temperature gradient throughout the disc, increases reliability by eliminating hot spots from fatigue. The AS series from Ametherm are suitable for high energy and short term high current applications.

Place holder video for YouTube video Limiting Inrush Current with NTC and PTC Themistors video

Learn how to limit inrush current using NTC and PTC thermistors in this presentation by Ametherm.

Many applications today, including industrial machinery, power tools and other high current equipment, use limiting inrush current as a major design consideration to combat the problematic effects of inrush current.

Inrush current occurs when a system powers on and experiences a spike in current. This current can be substantially higher than standard operating current. If not properly managed, it can reduce the effective operating life and impose damage to equipment. For example, inrush current could disable a cooling fan, eventually leading to total system failure.

Applications that are switched on and off quickly, such as welding equipment, present a particular concern for limiting inrush current. The limiting inrush current circuit must reset instantaneously during each power on to protect the system. This further complicates the management of inrush current.
