NTD03-010LF

Inrush Current Limiters (ICL) Overview

The YAGEO NTD03-010LF is an inrush current limiter (ICL) utilizing negative temperature coefficient (NTC) thermistor technology. It features a nominal resistance of 10 Ohms with a tolerance of ±15% and a rated current capacity of 3 Amperes. The component measures 11.00 mm (0.433 inches) in diameter. Designed for robust circuit protection, it operates within a temperature range of -40°C to +85°C.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high inrush currents during power-up sequences
• Utilizes NTC thermistor characteristics to transition from high cold resistance to low hot resistance
• Offers reliable protection against thermal stress and electrical surges

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Consumer electronic device power inputs
• Industrial control system protection circuits

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'LF' indicates lead-free compliance when sourcing. Confirm that the 10 Ohm resistance value aligns with the target inrush current requirements. Ensure the 3 A continuous current rating exceeds the maximum steady-state operating current of the application to prevent thermal runaway or component failure during normal operation.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on its 10 Ohm initial resistance to limit peak charging currents effectively. The 3 A rating suits moderate-power applications requiring surge protection. Consider the 11 mm diameter for adequate heat dissipation and mechanical fit within the enclosure constraints of the target electronic assembly.
