SL08 5R002-A

Inrush Current Limiters (ICL) Overview

The SL085R002-A is an NTC thermistor-based inrush current limiter (ICL) from the SL08 series, manufactured by Vishay Ametherm. It features a nominal resistance of 5 Ohms with a tolerance of 20% and a steady-state current rating of 2 A. The component utilizes an 8 mm diameter disc design suitable for PCB mounting. It operates within a standard temperature range and is UL approved for safety compliance.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient (NTC) thermistor technology to limit initial surge currents
• Provides automatic reset functionality after power cycle or fault clearance
• Designed for radial leaded surface mount installation on printed circuit boards

Inrush Current Limiters (ICL) Applications

• Power supply input stages for surge protection
• Consumer electronics AC/DC adapter circuits
• Industrial control system power inputs

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm package dimensions and lead configuration. Ensure the selected variant matches the required steady-state current and voltage ratings for the target application circuit. Cross-reference the UL file number if regulatory certification is mandatory for the end product.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the 5 Ohm nominal resistance value which balances inrush limiting effectiveness with steady-state power dissipation. Confirm that the 2 A current rating exceeds the maximum operating current of the load. Evaluate the thermal environment to ensure the device can dissipate heat without exceeding its maximum operating temperature limits during continuous operation.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL08 series of inrush current limiters, characterized by compact 8 mm disc geometry. The series offers various resistance values tailored for different current requirements. Vishay Ametherm produces these components using specialized ceramic materials optimized for high reliability and consistent performance across industrial and consumer applications.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other 5 Ohm, 2A, 8mm ICLs from the same family such as SL085R002. Verify mechanical footprint compatibility and electrical parameters before substitution. Alternative manufacturers may offer similar specifications but require validation of thermal and safety certifications.
