ICL201D13MIC

Inrush Current Limiters (ICL) Overview

The ICL201D13MIC is a negative temperature coefficient (NTC) thermistor from the Eaton ICL family, designed as an inrush current limiter. It features a nominal resistance of 20 Ohms at standard reference conditions and utilizes a Beta value of 3000 K for thermal characterization. The component has a physical size of 13 mm with lead spacing of 7.50 mm. It supports a maximum steady-state current of 3 A and exhibits a resistance tolerance of ±20%. The device is packaged in bulk format and complies with RoHS3 standards.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect electronic circuits during power-up phases
• Utilizes NTC characteristics to provide high initial resistance that decreases as temperature rises
• Supports continuous operation up to a maximum steady-state current of 3 A

Inrush Current Limiters (ICL) Applications

• Power supply input stages for inrush current suppression
• Protection of capacitive loads during startup
• Electronic equipment requiring controlled current ramp-up

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific order code against the manufacturer's official documentation to ensure correct Beta constant and tolerance specifications. Confirm that the 13 mm package dimensions and 7.50 mm lead spacing match the target PCB layout requirements. Check for RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the 3 A steady-state current rating exceeds the operational load of the intended circuit.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 20 Ohm initial resistance is required to limit peak charging currents in low-power applications. The 3000 K Beta value indicates a specific sensitivity profile suitable for general-purpose thermal compensation or limiting. Consider the 13 mm form factor for space-constrained designs where larger 20 mm variants are unsuitable. Validate that the ±20% resistance tolerance aligns with the circuit's design margins for inrush protection.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of NTC thermistors specifically engineered for inrush current limiting. The series offers various resistance values and physical sizes to accommodate different power levels. The ICL201D13MIC represents a mid-range option within the 13 mm size category, balancing resistance and current handling capabilities for consumer and industrial electronics.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other ICL family members such as ICL801D13MIC or ICL400D13MIC for similar form factors but different resistance values. Verify electrical compatibility before substituting, as Beta constants and steady-state current ratings vary significantly across the series.
