MF0703002M4BP0CST0

Inrush Current Limiters (ICL) Overview

The MF0703002M4BP0CST0 is an inrush current limiter manufactured by Songtian Electronics Co., Ltd. It features a nominal resistance of 3 Ohms with a tolerance of ±20%. The component is rated for a maximum steady-state current of 2 Amperes and has a physical length of 7 millimeters (0.276 inches). It belongs to the negative temperature coefficient thermistor category designed for circuit protection applications.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect electronic circuits from high initial surge currents during power-up phases.
• Utilizes negative temperature coefficient characteristics where resistance decreases significantly as temperature rises, allowing normal operating current flow.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Consumer electronics protection
• Industrial control circuit safeguarding

Inrush Current Limiters (ICL) Procurement Notes

Verify the manufacturer designation matches Songtian Electronic Technology (HK) Limited or Shantou Free Trade Zone Songtian Electronic Technology Co., Ltd. Confirm the part number includes the specific suffix CST0 to ensure correct packaging and specifications. Cross-reference the 3 Ohm resistance and 2A current rating against your circuit requirements before procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 3 Ohm initial resistance is required to limit inrush current in low-power applications up to 2 Amperes. Ensure the 7mm form factor fits the available board space. Consider the thermal environment to guarantee the NTC reaches its low-resistance state effectively during operation without overheating.

Inrush Current Limiters (ICL) Part Context

This part is part of Songtian's ICL product line, which also includes variants like MF0920001M4BN0CSB0 and MF1105004M4EP0CST0. These components are distributed by entities such as DigiKey and WIN SOURCE. The company specializes in ceramic capacitors, film capacitors, metal oxide varistors, and NTC thermistors.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include MF0705002M4BP0CST0 if higher current handling is needed, or MF0920001M4BN0CSB0 for different resistance values. Verify that any replacement maintains the 7mm axial leaded package and compatible thermal characteristics.
