AS32R036

Overview

The AS32R036 is a negative temperature coefficient (NTC) thermistor inrush current limiter manufactured by Vishay Ametherm. Designed for PCB mounting with radial termination, this component features a nominal resistance of 1 Ohm with a tolerance of ±25%. It supports a continuous current rating of 36 A and withstands voltage ratings up to 480 VAC. The unit has a cylindrical body diameter of 30.00 mm (1.181 inches) and utilizes a bulk packaging format.

Feature Summary

• Utilizes NTC thermistor technology to provide high initial resistance that decreases as temperature rises during operation
• Radial leaded construction enables direct through-hole PCB mounting without requiring additional hardware
• Engineered to absorb high energy surges during power-up phases to protect downstream circuitry

Applications

• Power supply input stages
• Motor drive circuits
• Industrial control systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct resistance and current ratings. Confirm package dimensions and lead spacing match the target PCB footprint. Check RoHS compliance status and manufacturing origin requirements before finalizing procurement orders.

Selection Notes

Select this component based on the required steady-state current capacity and peak inrush energy absorption needs. Ensure the operating environment allows sufficient thermal dissipation around the 30 mm diameter body. Verify that the 1 Ohm initial resistance aligns with the system's startup current limiting specifications.

Part Context

This part belongs to the AS32 series of inrush current limiters from Vishay Ametherm. The series offers various resistance values and current ratings tailored for different power levels. These components are standard solutions for managing capacitive load charging currents in electronic equipment.

Replacement Considerations

Consult the official Vishay Ametherm cross-reference documentation for verified substitute part numbers. Do not assume interchangeability with generic NTC thermistors due to specific energy handling capabilities.
