MS3210015BE

Inrush Current Limiters (ICL) Overview

The MS3210015BE is a MegaSurge NTC thermistor inrush current limiter from Vishay Ametherm. It features a nominal resistance of 10 ohms with a tolerance of ±25%. The component supports a maximum steady-state current of 15 A and has a diameter of 31 mm. It utilizes radial leads with a pitch spacing of 6.75 mm for PCB mounting. The device offers a dissipation factor of 63.7 mW/°C, providing efficient thermal management during operation.

Inrush Current Limiters (ICL) Feature Summary

• Provides simple one-component surge protection as an alternative to wire-wound resistors combined with timers or relays
• Utilizes negative temperature coefficient characteristics to limit initial charging currents effectively
• Designed for radial leaded through-hole PCB mounting applications

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive circuits
• Transformer primary side protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'BE' against official Vishay documentation to confirm custom specifications. Standard MS3210015B variants may differ in packaging or marking. Confirm availability status as distribution channels may indicate restricted supply. Ensure the selected component matches the required 10-ohm resistance and 15-ampere current rating for the target circuit design.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10-ohm initial resistance and 15-ampere continuous current capacity are required. The 31 mm diameter provides sufficient thermal mass for moderate energy absorption. Consider the 6.75 mm lead pitch for standard PCB layouts. This series serves as a direct replacement for discrete resistor and relay combinations in compact designs.

Inrush Current Limiters (ICL) Part Context

The MS3210015BE belongs to the Vishay Ametherm MegaSurge MS series of NTC thermistors. These components are engineered specifically for inrush current limiting in electronic power systems. The series replaces complex active or passive switching solutions with a single passive element, simplifying circuit topology while maintaining reliable surge suppression performance.

Inrush Current Limiters (ICL) Replacement Considerations

The MS3210015B is a closely related variant within the same series. Verify if the 'E' suffix denotes specific packaging or marking differences rather than electrical changes. Cross-reference datasheets to ensure identical resistance, current ratings, and physical dimensions before substitution.
