SL2210009

Overview

The Vishay Ametherm SL2210009 is a radial leaded inrush current limiter designed for PCB mounting. It features a 22 mm diameter ceramic body with a nominal resistance of 10 Ohms and a tolerance of ±20%. The component is rated for a steady-state current of 9 A and supports voltage ratings of 115 VAC and 230 VAC. Physical dimensions include a width of 6 mm, lead diameter of 1 mm, and lead spacing of 7.8 mm. It operates within a temperature range of -40°C to +85°C and carries UL approval.

Feature Summary

• Radial leaded construction for through-hole PCB integration
• Thermistor-based mechanism to limit initial surge currents
• UL certified for safety compliance
• RoHS compliant manufacturing

Applications

• Power supply input stages
• Transformer primary circuits
• Capacitor charging protection
