• Provides simple one-component alternative to wire wound resistors with timers and relays
• Increases safety by eliminating fire hazards associated with traditional limiting methods

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Electronic equipment requiring surge protection
• Circuits replacing resistor-timer relay combinations

Inrush Current Limiters (ICL) Procurement Notes

Verify the exact physical dimensions and lead configuration against the official datasheet before integration, as this part is designated as a custom item. Confirm that the 20-ohm resistance and 5-amp current ratings align with your system's steady-state operational requirements to ensure reliable performance without premature failure or excessive voltage drop.

Inrush Current Limiters (ICL) Selection Notes

Select this component when standard off-the-shelf limiters do not meet specific spatial or electrical constraints. The 23mm form factor allows for tailored mechanical integration. Ensure the application does not exceed the 180-joule energy limit to maintain device integrity during startup transients.
