SL2230005B

Inrush Current Limiters (ICL) Overview

The SL2230005B is a negative temperature coefficient (NTC) thermistor inrush current limiter from the Vishay Ametherm SL22 series. It features a nominal resistance of 30 ohms at 25°C and supports a steady-state current rating of 5 A. The component utilizes a 22 mm disc diameter with a specialized kinked lead configuration for mechanical stability. Designed for robust performance, it effectively limits initial surge currents while maintaining low power dissipation during normal operation.

Inrush Current Limiters (ICL) Feature Summary

• Kinked lead design provides enhanced mechanical retention on printed circuit boards
• Negative temperature coefficient characteristic enables automatic resistance reduction after startup
• Disc form factor allows for compact integration into high-current power supply circuits

Inrush Current Limiters (ICL) Applications

• Switching mode power supplies
• AC/DC converter input stages
• Industrial control systems
• Consumer electronics power inputs

Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific part number suffix 'B' corresponds to the kinked lead variant as documented in the official Vishay datasheet. Confirm that the 30-ohm resistance and 5-ampere current ratings align with the target application's thermal and electrical requirements before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 30-ohm initial impedance is required to suppress inrush currents up to 5 amperes. The 22-millimeter size accommodates higher energy absorption compared to smaller packages. Ensure the operating environment does not exceed the maximum allowable surface temperature specified in the technical documentation.

Inrush Current Limiters (ICL) Part Context

This device belongs to the SL22 series of NTC thermistors manufactured by Vishay Ametherm. The series offers various resistance values and current ratings tailored for different power levels. The SL2230005B specifically addresses applications requiring moderate surge suppression with a standardized 22-millimeter footprint.

Inrush Current Limiters (ICL) Replacement Considerations

Consult the official Vishay Ametherm cross-reference documentation for verified substitute part numbers. Do not assume interchangeability based solely on similar resistance or current ratings without verifying package dimensions and thermal characteristics.
