SL3210015B227

Overview

The Vishay Ametherm SL3210015B227 is a radial leaded NTC thermistor designed for inrush current limiting. It features a nominal resistance of 10 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 15 Amps and can absorb up to 150 Joules of energy. It is rated for operation up to 65°C ambient temperature.

Feature Summary

• Radial leaded construction for through-hole PCB mounting
• Negative temperature coefficient (NTC) behavior for surge suppression
• High energy absorption capacity for circuit protection

Applications

• Power supply input stages
• Transformer primary circuits
• Capacitive load switching

Procurement Notes

Verify the specific suffix B227 against the manufacturer's official datasheet to confirm physical dimensions and lead configuration. Ensure the selected variant matches the required thermal characteristics and mechanical constraints for the target assembly process.

Selection Notes

Select this component when a 10 Ohm initial resistance and 15 Amp steady-state current are required. Consider the 150 Joule energy rating for capacitive loads. Verify that the operating environment does not exceed the specified thermal limits for reliable performance.

Part Context

This part belongs to the SL32 series of inrush current limiters from Vishay Ametherm. These components utilize NTC technology to protect electronic circuits from high initial charging currents during power-up, ensuring stable operation and preventing damage to sensitive downstream components.

Replacement Considerations

Cross-reference with other Vishay Ametherm SL32 series variants such as SL3210015B if identical electrical parameters are needed but different packaging or lead configurations are preferred. Verify compatibility with existing board layouts.
