• Functions as an inrush current limiter using NTC thermistor technology
• Provides high steady-state current handling capability
• Features low initial resistance for effective surge suppression
• Complies with RoHS directives and lead-free termination requirements

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive circuits
• Transformer protection systems
• General electronic equipment surge suppression

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix 'M' against the manufacturer's official datasheet to confirm exact tolerance and packaging specifications. Ensure that the required steady-state current rating of 12 A aligns with the application's operational limits. Confirm TUV certification requirements if mandated by the end-product safety regulations. Cross-reference the 20 mm disc dimensions with PCB layout constraints prior to procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a robust inrush current limiting solution is needed for circuits drawing up to 12 A. The 2-ohm initial resistance offers a balance between surge suppression and power loss. Consider the thermal environment, as steady-state performance depends on ambient temperature. The 20 mm form factor suits through-hole mounting applications where space allows for larger thermal mass components compared to smaller surface-mount alternatives.

Inrush Current Limiters (ICL) Part Context

The NTL12-002M is part of YAGEO's NT Series of NTC thermistors. This series is engineered specifically for inrush current limiting applications in power electronics. The component utilizes ceramic semiconductor materials to achieve negative temperature coefficient characteristics, allowing it to transition from high resistance at cold start to low resistance during normal operation.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 2-ohm resistance, 12 A current rating, and 20 mm diameter. Verify that alternative manufacturers offer equivalent TUV approvals and RoHS compliance. Ensure the replacement part maintains similar energy absorption capabilities and thermal recovery times to prevent circuit damage during repeated power cycles.
