SL187R010361

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL187R010361 is a Negative Temperature Coefficient (NTC) thermistor designed as an inrush current limiter. It features a nominal resistance of 7 Ohms with a tolerance of 20%. The component supports a steady-state current rating of 10 A and operates at voltage ratings of 115 VAC and 230 VAC. It utilizes a radial leaded package with a diameter of 19 mm and a width of 6 mm. The leads have a diameter of 1 mm and a spacing of 7.8 mm. The unit weighs approximately 9.117 g.

Inrush Current Limiters (ICL) Feature Summary

• Provides high initial resistance to limit surge currents during power-up, reducing stress on downstream components.
• Exhibits self-regulating behavior by decreasing resistance as temperature rises during operation.
• Designed for robust PCB mounting with radial leads suitable for through-hole assembly.

Inrush Current Limiters (ICL) Applications

• Protection in AC/DC power supply input stages
• Surge current limiting in industrial control systems
• Inrush protection for consumer electronics

Inrush Current Limiters (ICL) Procurement Notes
