SG200C001

Inrush Current Limiters (ICL) Overview

The SG200C001 is a negative temperature coefficient (NTC) thermistor inrush current limiter from the SURGE-GARD series. It features a nominal resistance of 5 Ohms at 25°C with a tolerance of ±15%. The device supports a maximum continuous current of 7 A and exhibits a nominal hot resistance of 0.07 Ohms at rated current. Physical dimensions include a diameter of 15.24 mm (0.600 inches). It utilizes radial leads for PCB mounting.

Inrush Current Limiters (ICL) FAQ

What is the hot resistance value?

The nominal hot resistance at maximum continuous current is 0.07 Ohms.

Is this component suitable for high-frequency switching?

No, NTC thermistors require thermal recovery time after current flow ceases, making them unsuitable for rapid cycling or high-frequency applications.
