NTL12-002MF

Inrush Current Limiters (ICL) Overview

The YAGEO NTL12-002MF is a Negative Temperature Coefficient (NTC) thermistor designed for inrush current limiting applications. It features a nominal resistance of 2 Ohms with a tolerance of ±20%. The component is rated to handle a steady-state current of 12 Amperes. It utilizes a disc package configuration with a diameter of 20mm, specifically sized at 24.00mm (0.945 inches). This device is engineered to protect electronic circuits from high initial surge currents during power-up phases.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to suppress high startup surges
• Utilizes negative temperature coefficient characteristics for self-regulating protection
• Constructed with a robust 20mm disc form factor for thermal stability

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix and marking codes against the manufacturer's official datasheet to ensure compatibility with existing board layouts. Confirm that the 2 Ohm resistance value aligns with the system's steady-state operational requirements. Check for any recent product lifecycle notifications or discontinuation alerts from YAGEO prior to finalizing procurement plans.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state current rating of 12A and the specific cold resistance value of 2 Ohms. Ensure the physical dimensions fit within the designated PCB footprint. Evaluate the thermal environment to guarantee the thermistor can dissipate heat effectively during continuous operation without exceeding its maximum operating temperature limits.

Inrush Current Limiters (ICL) Part Context

This part belongs to the NT series of NTC thermistors manufactured by YAGEO. These components are specialized for protecting sensitive electronic components from damage caused by excessive current flow during the initial energization of a circuit. The series is known for providing reliable performance in industrial and consumer electronics applications requiring surge protection.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 2 Ohm resistance, 12A current rating, and 20mm diameter. Verify that alternative parts meet AEC-Q200 automotive qualification standards if used in automotive contexts. Cross-reference mechanical mounting requirements to ensure interchangeability.
