Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version from Songtian Electronics to confirm thermal characteristics and pulse rating specifications. Ensure the application environment temperature aligns with the component's derating curves. Confirm that the 2.5 Ohm resistance value meets the system's inrush current requirements without causing excessive voltage drop during normal operation.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 2.5 Ohm resistance is required to manage surge currents in applications handling up to 8 Amperes. The 20 mm form factor suits standard through-hole PCB layouts. Consider the thermal dissipation capabilities relative to the duty cycle and ambient temperature conditions of the target equipment.

Inrush Current Limiters (ICL) Part Context

This part belongs to the series of ceramic inrush current limiters produced by Songtian Electronics. These components utilize positive temperature coefficient materials to increase resistance as current flows, thereby protecting downstream sensitive electronic components from damage caused by sudden power surges.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 2.5 Ohm nominal resistance, 8 A current rating, and 20 mm diameter. Verify that alternative manufacturers offer identical thermal and electrical performance profiles to ensure circuit reliability without modification.
