SL1290101

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL1290101 is a Negative Temperature Coefficient (NTC) thermistor inrush current limiter designed for electronic circuit protection. It features a nominal resistance of 900 Ohms with a tolerance of ±20% at 25°C. The component supports a maximum steady-state current of 700 mA and has a physical diameter of 12.00 mm (0.472 inches). These specifications define its electrical performance envelope and mechanical footprint for PCB integration.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to provide high initial resistance that decreases as temperature rises during operation.

Inrush Current Limiters (ICL) Applications

• General electronic circuit inrush current limiting

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix and tolerance requirements against the design schematic before ordering. Confirm thermal management strategies are adequate for the 700 mA continuous current rating. Ensure the 12 mm radial package dimensions fit within the designated PCB area without interference from adjacent components or enclosure constraints.

Inrush Current Limiters (ICL) Selection Notes

Select this component when the application requires a 900 Ohm initial impedance to restrict startup surge currents. The 700 mA current rating must exceed the circuit's operating current. Consider the 12 mm form factor for available board space. Validate that the thermal recovery time aligns with the expected power cycling frequency of the target equipment.

Inrush Current Limiters (ICL) Part Context
