NTE03-012L

Inrush Current Limiters (ICL) Overview

The YAGEO NTE03-012L is a Negative Temperature Coefficient (NTC) thermistor designed for inrush current limiting applications. It features a nominal resistance of 12 Ohms with a tolerance of ±15%. The component supports a steady-state current rating of 3 Amperes and operates within a temperature range of -40°C to +170°C. It utilizes a radial leaded package with a 5 mm lead spacing and a body diameter of 10 mm, suitable for through-hole PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high inrush currents during power-up sequences
• Utilizes negative temperature coefficient characteristics to reduce resistance as temperature increases
• Designed for robust thermal performance across wide operating temperature ranges

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive circuits
• Transformer protection systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix and packaging configuration against the manufacturer's latest datasheet before procurement. Confirm that the selected variant matches the required resistance tolerance and current rating for the target application. Ensure compliance with RoHS directives if environmental standards are mandated. Cross-reference the Mouser or distributor part number to confirm availability status and lead times.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required nominal resistance value and maximum steady-state current capacity. Ensure the physical dimensions fit the available PCB footprint and lead spacing constraints. Evaluate the thermal environment to confirm the device can handle the expected energy dissipation without exceeding maximum temperature limits. Consider the switching frequency and duty cycle if used in repetitive cycling applications.

Inrush Current Limiters (ICL) Part Context

This part belongs to the NT series of NTC thermistors manufactured by YAGEO. These components are specialized for inrush current limiting rather than temperature sensing. The series offers various resistance values and package sizes to accommodate different power levels and form factors in electronic equipment design.

Inrush Current Limiters (ICL) Replacement Considerations

Equivalent parts from other manufacturers may include similar radial NTC inrush limiters with matching 12 Ohm resistance and 3A current ratings. Verify mechanical dimensions and lead spacing compatibility when substituting. Check electrical parameters such as B-value and energy absorption capability to ensure functional equivalence.
