AS3210015

Overview

The AS3210015 is a radial leaded negative temperature coefficient (NTC) thermistor designed as an inrush current limiter. It features a nominal resistance of 10 Ohms with a tolerance of ±25% at 25°C. The component supports a maximum steady-state current of 15 Amperes and operates within a thermal environment up to 65°C. Mechanically, it has a diameter of approximately 30mm with a pitch spacing of 6.8mm.

Feature Summary

• Provides inrush current protection for input energy levels ranging from 250 to 1000 joules
• Utilizes NTC characteristics to limit initial surge currents during power-up
• Supports steady-state currents between 10A and 50A depending on specific series configurations

Applications

• Power supply input stages
• Transformer primary circuits
• Capacitor charging protection

Procurement Notes

Verify the exact part number suffix against official Vishay Ametherm documentation to ensure correct resistance and current ratings. Confirm availability status as distribution channels may indicate restricted supply or regional limitations. Cross-reference mechanical dimensions and lead spacing with PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component based on the required nominal resistance value of 10 Ohms and the maximum steady-state current capacity of 15 Amperes. Ensure the application's input energy does not exceed the specified 1000 joules limit. Verify that the operating temperature range accommodates the device's thermal dissipation factor and ambient conditions.

Part Context

This component belongs to the AS32 series of inrush current limiters manufactured by Vishay Ametherm. These devices are specialized thermistors intended for circuit protection applications where high initial surge currents must be controlled to prevent damage to downstream components.
