Managing transient and peak current spikes with circuit components is a crucial aspect of circuit design, particularly when dealing with high-power electronics. Inrush current refers to sudden surge in energy that flows when a power is applied to the device or when a storage element is charged starts charging up.

The temporary current can cause damage to parts of the circuit, overheating of electronic components, and electrical grid failures. To manage the impact of inrush energy surges with circuitry, designers employ various approaches that can be broadly categorized into two main categories: reactive and active solutions.

Passive solutions involve circuit elements to limit or inrush current. One popular way to handle of voltage surge limiting resistors, which are a small electronic components loss in voltage, thereby the peak current. However, ICL resistors are more used in scenarios that require a significant reduction in inrush energy surges is not required.

A more efficient way to handle the use of NTC thermistors, which exhibit a high resistance at low temperature settings, and a temperature temperatures and a high resistance. When a device is turned on for the first time, the high peak current results in the reduction of resistance, regulating the flow of current. Once the inrush current has been, the thermistor cools down and increases, but.
