AS352R035

Overview

The AS352R035 is a radial leaded inrush current limiter from the MS35 series, manufactured by Vishay Ametherm. It features a nominal resistance of 2 Ohms with a tolerance of ±25% and a continuous current rating of 35 A. The component supports voltage ratings of 120 VAC, 240 VAC, 480 VAC, and 680 VAC. Physical dimensions include a diameter of 37 mm (approx. 36 mm per distributor data) and a width of 6.5 mm to 8.5 mm. Lead spacing is 19 mm with a pitch distribution of 7.5 mm. It has a loss factor of 96 mW/C and weighs approximately 31 g.

Feature Summary

• Designed to absorb and minimize high input energy during power-up sequences
• Capable of withstanding significant steady-state current loads without degradation
• UL recognized for safety compliance in electronic applications

Applications

• Power supply input stages
• Transformer primary circuits
• Motor drive inputs

Procurement Notes

Verify the specific suffix against official datasheets, as variations may exist between MS35 and AS35 designations. Confirm physical dimensions and lead spacing match PCB layout requirements. Ensure thermal management allows for adequate heat dissipation during operation. Check RoHS compliance status if required by project specifications.

Selection Notes

Select based on the 2 Ohm resistance value and 35 A continuous current capability. Consider the 750 Joules inrush energy absorption capacity for circuit protection. Evaluate the radial leaded package for through-hole mounting compatibility. Compare loss factor and thermal characteristics against similar components in the MS35 family.

Part Context

This component belongs to the MS35 series of NTC thermistors designed specifically for inrush current limiting. The series offers various resistance and current ratings to suit different power levels. Vishay Ametherm manufactures these devices to provide reliable protection against high initial charging currents in AC and DC circuits.

Replacement Considerations

MS352R035 is a confirmed substitute part number within the same product line.
