SL10 25002-B

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL10 25002-B is a Negative Temperature Coefficient (NTC) thermistor belonging to the SL10 series, designed specifically as an inrush current limiter. This component features a disc diameter of 10 mm and provides a nominal resistance of 25 Ohms at 25°C with a tolerance of ±25%. It is rated for a steady-state current of 2 A and utilizes radial leads for through-hole mounting. The device is engineered to protect sensitive electronic circuits from high initial charging currents during power-up.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an NTC inrush current limiter to suppress peak charging currents
• Features a compact 10 mm disc body suitable for space-constrained designs
• Utilizes radial leaded construction for standard through-hole PCB integration

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct tolerance and thermal characteristics. Confirm that the 2 A current rating aligns with the application's steady-state requirements. Check RoHS compliance status via the datasheet. Ensure the 10 mm package size fits the designated PCB footprint. Validate lead spacing compatibility before procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 25 Ohm resistance value and 2 A current handling capability. Consider the SL10 series' thermal time constant relative to the load's charging profile. Evaluate the maximum allowable body temperature under continuous operation. Compare physical dimensions against available board space. Assess environmental operating conditions against the component's specified temperature range.

Inrush Current Limiters (ICL) Part Context

The SL10 series represents Vishay Ametherm's line of small-diameter inrush current limiters. These components are widely used in consumer electronics and industrial power supplies where moderate current limiting is required. The SL10 25002-B is part of this established family, offering reliable performance for general-purpose AC/DC conversion applications.

Inrush Current Limiters (ICL) Replacement Considerations

Consult the official Vishay Ametherm cross-reference guide for verified substitutes. Ensure any replacement maintains identical 25 Ohm resistance and 2 A current ratings. Verify mechanical compatibility including the 10 mm diameter and lead configuration. Confirm electrical parameters match the original design specifications.
