Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pin configuration and mechanical tolerances. Confirm that the selected variant matches the required thermal characteristics and voltage ratings for the target application environment. Cross-reference the part number with authorized distributors to ensure authenticity and compliance with RoHS standards.

Selection Notes

Select this component based on the required nominal resistance and maximum current handling capabilities. Ensure the physical footprint fits the PCB layout constraints regarding lead spacing and body diameter. Evaluate the thermal environment to confirm the device can dissipate heat effectively during normal operation without exceeding temperature limits.

Part Context

This component belongs to the MS35 series of MegaSurge inrush current limiters manufactured by Vishay Ametherm. The series is designed to protect electronic circuits from high initial charging currents when power is applied. These NTC thermistors provide effective surge protection while maintaining low power consumption during steady-state operation.

Replacement Considerations

Direct substitutes within the same series include MS3510018. Verify compatibility by comparing electrical parameters such as resistance, current rating, and energy absorption capacity.
