MF2503009M1DN0CSB0

Inrush Current Limiters (ICL) Overview

The MF2503009M1DN0CSB0 is an inrush current limiter (ICL) manufactured by Songtian Electronics Co., Ltd. This component utilizes negative temperature coefficient (NTC) thermistor technology to manage electrical surges during power-up sequences. It features a nominal resistance of 3 ohms with a tolerance of ±20%. The device is rated for a maximum steady-state current of 9 amperes and has a cylindrical body diameter of 25 millimeters. These specifications define its capacity to absorb initial energy spikes while maintaining operational stability in connected circuits.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high inrush currents during initial power application
• Utilizes NTC thermistor characteristics to reduce resistance as temperature increases
• Designed for reliable protection against electrical stress in sensitive electronic systems

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Consumer electronics devices
• Industrial control equipment

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix and package configuration when sourcing this component, as manufacturers may update packaging formats or revision codes without altering core electrical performance. Confirm that the supplier provides original manufacturer documentation to ensure authenticity. Cross-reference the part number with official distributor catalogs to validate availability status and lead times prior to finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required resistance value and current handling capacity for the target circuit design. Ensure the physical dimensions fit within the available board space constraints. Evaluate the thermal management requirements to guarantee the thermistor operates within safe temperature limits during continuous operation and surge events.

Inrush Current Limiters (ICL) Part Context

This part belongs to the MF series of inrush current limiters produced by Songtian Electronics. The series offers various resistance and current ratings to suit different power levels. The company specializes in manufacturing ceramic capacitors, film capacitors, varistors, and NTC thermistors, serving industries such as power supplies, lighting, home appliances, and automotive applications.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 3-ohm resistance, 9A current rating, and 25mm diameter. Verify compatibility with equivalent NTC thermistor models from other manufacturers if supply chain constraints require alternative sourcing.
