The SL15 2R506 inrush current limiting thermistor from Ametherm offers a maximum steady state current of 6A (up to +25ยฐC), resistance of 2.5ฮฉ ยฑ20% (at 25ยฐC) and a maximum recommended energy rating of 40J. The Ametherm SL series suppresses surge currents that occur when electrical circuits are switched on, preventing serious damage to sensitive electronic components if their rated current values are exceeded. Connected in series with the load, at “switch-on” they limit the current due to its relatively high cold resistance. As a result of current flow, the thermistor self-heats and in turn reducing its resistance value so that once the initial surge current has been safely held off, the resistance in the thermistor is maintained at a low value to maximise efficiency
Typical applications for the SL series include:

Limiting Inrush Current with NTC and PTC Thermistors 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. |

DC Motor Inrush Current and What You Need to Know What does inrush current have to do with DC motors? This video answers that question by discussing the cause of DC motor inrush current and how to prevent the inrush of current at startup from possibly damaging the DC motor with the use of Ametherm’s Inrush Current Limiters. They start by explaining how a DC motor functions, its applications and key components, how inrush current factors in, how to solve the problem of inrush current, and how to select the right inrush current limiter for your application with three easy steps. |
