SL0350001

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL0350001 is a Negative Temperature Coefficient (NTC) thermistor designed as an inrush current limiter. It features a nominal resistance of 50 Ohms with a tolerance of ±20%. The component supports a maximum steady-state current of 1 Ampere at temperatures up to 65°C. Its physical dimensions include a diameter of 3mm, and it is classified under the MegaSurge series for surge protection applications.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to provide high initial resistance that decreases as temperature rises during operation.
• Engineered to suppress high inrush currents during power-up phases in electronic circuits.
• Offers robust energy absorption capabilities to withstand transient surge events without failure.

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for the SL0350001 to confirm thermal characteristics and mechanical tolerances. Ensure the application environment does not exceed the maximum recommended energy limits of 2 Joules or the actual energy failure threshold of 4 Joules. Confirm radial lead compatibility with the target PCB layout before procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when circuit design requires limiting initial surge currents to protect downstream components. The 50-Ohm resistance value is suitable for moderate voltage inputs where 1-Ampere continuous current is sufficient. Consider the 3mm diameter for space-constrained PCB layouts requiring radial mounting.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Vishay Ametherm SL03 series of MegaSurge inrush current limiters. These components are specialized NTC thermistors distinct from standard resistive elements, focusing on transient suppression rather than steady-state signal processing or power dissipation.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes within the same series include parts with matching 50-Ohm resistance and 1-Ampere current ratings. Verify dimensional compatibility and thermal performance curves when considering alternative manufacturers' NTC thermistors for inrush limiting.
