SL2210008BT

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL2210008BT is a negative temperature coefficient (NTC) inrush current limiter belonging to the SL22 series. It features a nominal resistance of 10 Ω with a tolerance of ±25% at 25°C. The device supports a maximum steady-state current of 8 Amps and can withstand a maximum recommended energy of 200 Joules. Designed for robust performance, it utilizes a 22 mm custom package configuration suitable for high-power applications.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of inrush currents during power-up sequences
• Utilizes NTC technology for automatic resistance adjustment based on temperature
• Engineered for high thermal stability and long-term reliability

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Industrial automation systems
• Embedded system power management

Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific ordering suffix BT matches the required packaging format, as suffixes often denote bulk or tape-and-reel configurations rather than functional changes. Confirm the 22 mm physical dimensions align with the target PCB layout constraints. Ensure the 8A steady-state rating exceeds the circuit's continuous operating current to prevent thermal failure. Cross-reference the UL certification status if safety compliance is mandatory for the end product.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10 Ω initial resistance is required to limit peak charging currents effectively. The 8A capacity suits moderate-to-high power loads where standard limiters may overheat. Consider the 200 Joule energy rating against the capacitive load characteristics of the application. The SL22 series offers a balance of size and performance for through-hole or specialized mounting scenarios.
