SL22 14005-A

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL2214005A is a Negative Temperature Coefficient (NTC) thermistor designed as an inrush current limiter. It features a nominal resistance of 14 Ohms with a tolerance of ±25% at 25°C. The component supports a maximum steady-state current of 5 A and has a diameter of 22 mm. It utilizes radial leads with a spacing of 7.8 mm for through-hole PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to absorb high inrush currents during equipment startup
• Provides effective protection for transformers against surge damage
• Features radial kinked lead configuration for secure PCB installation

Inrush Current Limiters (ICL) Applications

• Transformer protection from inrush current
• DC inrush current limiting circuits
• General electronic equipment power supply input stages

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'A' corresponds to the kinked lead variant, as standard versions may differ in termination style. Confirm RoHS3 compliance status and check for any specific UL approval markings required for your target market. Ensure the 5 A steady-state rating aligns with your circuit's operational requirements before finalizing the order.

Inrush Current Limiters (ICL) Selection Notes

Select this part when a 14 Ohm initial resistance is required to limit surge current to approximately 5 A. The 22 mm diameter provides sufficient thermal mass for repeated cycling. Consider the ±25% resistance tolerance in your design margins. Verify that the radial kinked lead form factor fits your PCB layout constraints compared to straight lead alternatives.

Inrush Current Limiters (ICL) Part Context

This component belongs to the SL22 series of BigAMP inrush current limiters manufactured by Vishay Ametherm. The series offers various resistance and current ratings within the 22 mm package size. The SL2214005A specifically addresses applications needing moderate surge suppression with a 14 Ohm baseline resistance.

Inrush Current Limiters (ICL) Replacement Considerations

The SL2214005 is a related part number within the same series but may feature straight leads instead of kinked ones. Verify lead configuration compatibility before substitution. Other SL22 variants with different resistance values are not direct replacements due to differing current limiting characteristics.
