MS3250006L

Inrush Current Limiters (ICL) Overview

The MS3250006L is a MegaSurge NTC inrush current limiter manufactured by Vishay Ametherm. It features a nominal resistance of 50 ohms with a tolerance of ±25% at 25°C. The device supports a maximum steady-state current of 6 A and can withstand up to 250 Joules of recommended energy, with an actual energy failure threshold of 500 J. It utilizes 16 AWG leads and has a diameter of approximately 32 mm.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient (NTC) technology for effective inrush current suppression
• Designed to handle high energy pulses without permanent damage
• Features leaded construction for through-hole mounting applications

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits
• Capacitor charging protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the official Vishay datasheet to ensure correct lead configuration and packaging. Confirm that the required thermal characteristics align with the application's ambient temperature conditions. Check for RoHS compliance status if restricted substances are a concern for the target market.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state current rating and initial resistance value. Ensure the expected inrush energy does not exceed the 250 Joule recommendation to maintain reliability. Consider the physical size constraints due to the 32 mm diameter when designing the PCB layout.

Inrush Current Limiters (ICL) Part Context

This part belongs to the MS series of MegaSurge inrush current limiters. These components are specifically engineered to protect electronic equipment from high surge currents during power-up. The series offers various resistance and current ratings to suit different power levels.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Vishay Ametherm parts within the MS32 series with matching electrical parameters. Verify compatibility with equivalent NTC thermistors from other manufacturers only if they meet the exact resistance, current, and energy specifications.
