NTG04-020M

Inrush Current Limiters (ICL) Overview

The NTG04-020M is a leaded Negative Temperature Coefficient (NTC) thermistor manufactured by YAGEO, designed for inrush current limiting applications. It features a nominal resistance of 20 Ohms at standard reference temperature and supports a steady-state current rating of 4 Amperes. The component utilizes a 13 mm bead form factor suitable through-hole mounting. It operates within a standard industrial temperature range, providing effective surge suppression during power-up sequences to protect downstream electronic circuits from high initial current spikes.

Inrush Current Limiters (ICL) Feature Summary

• Provides reliable inrush current limitation for sensitive electronic loads
• Utilizes NTC technology for automatic resistance adjustment based on thermal state
• Supports high steady-state current handling capabilities

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Consumer electronics protection
• Industrial equipment surge suppression

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version with the manufacturer or authorized distributor before procurement. Confirm that the 13 mm bead package dimensions align with the target PCB layout requirements. Ensure the 4 A steady-state current rating meets the operational demands of the intended circuit design without exceeding thermal limits under worst-case ambient conditions.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 20 Ohm nominal resistance and 4 A current capacity are required for inrush control. Consider the 13 mm physical size constraints for board space allocation. Evaluate the thermal dissipation characteristics relative to the enclosure environment to ensure long-term reliability during repeated power cycling events.

Inrush Current Limiters (ICL) Part Context

This part belongs to YAGEO's NTC thermistor portfolio focused on circuit protection. It complements other series like RC and AA resistors by addressing transient energy management rather than passive signal conditioning. The product line targets industries requiring robust surge protection solutions for AC/DC power inputs.
