SL10 5R004-B

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL10 5R004-B is a Negative Temperature Coefficient (NTC) inrush current limiter designed for PCB mounting. It features a nominal resistance of 5 Ohms with a tolerance of ±20%. The component supports a maximum steady-state current of 4 A at 25°C and withstands up to 110 VAC to 126 VAC. Physical dimensions include a diameter of 10.00 mm (0.394 inches). It operates within a temperature range of -40°C to +150°C.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to provide high initial resistance that decreases as temperature rises, effectively limiting surge currents during power-up.
• Designed for radial leaded through-hole installation on printed circuit boards.
• Capable of absorbing significant energy pulses without failure, ensuring reliable protection against repetitive inrush events.

Inrush Current Limiters (ICL) Applications

• Protection of AC/DC power supplies against high startup currents
• Surge current limitation in consumer electronics equipment
• Inrush current control in industrial power distribution systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official datasheet to confirm physical dimensions and electrical characteristics match the design requirements. Ensure the operating environment stays within the specified -40°C to +150°C range. Confirm that the 4 A steady-state current rating is sufficient for the target application's continuous load conditions.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 5 Ohm cold resistance and 4 A current handling capability. Consider the 10 mm body size for PCB layout constraints. Evaluate the thermal dissipation constant of 11.0 mW/°C to ensure adequate heat management in the final assembly. Verify voltage ratings align with the system's peak operating voltage.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL10 series of inrush current limiters from Vishay Ametherm. The series offers various resistance and current combinations tailored for different power levels. These components are widely used in general-purpose electronic devices requiring robust surge protection during initialization phases.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 5 Ohm resistance, 4 A current rating, and 10 mm diameter. Check alternative manufacturers like EPCOS or Murata for equivalent NTC inrush limiters with identical form factors and electrical specifications.
