B57236S0160M000

Overview

The B57236S0160M000 is a radial leaded NTC thermistor designed for inrush current limiting. It features a 16 Ω resistance at 25 °C with a ±20% tolerance and a rated AC voltage of 230 VAC. The component supports a maximum continuous current of 2.9 A and dissipates up to 2.1 W. Operating within a temperature range of -55 °C to +170 °C, it utilizes a disk package measuring 11.5 mm in diameter and 6 mm in depth.

Feature Summary

• Provides effective suppression of high inrush currents during power-up sequences
• Features self-resetting capability that automatically returns to high resistance after thermal cooling
• Constructed with coated disk design suitable for through-hole mounting applications

Applications

• Inrush current limiting in AC/DC power supplies
• Protection circuits for switching power modules
• Surge current suppression in consumer electronic devices

Procurement Notes

Verify the manufacturer designation on the component marking, as TDK has discontinued the EPCOS brand name for passive components. Ensure the specific part number matches the required electrical parameters, particularly the 16 Ω resistance and 2.9 A current rating, to confirm compatibility with the intended circuit design.

Selection Notes

Select this component when designing circuits requiring robust protection against initial surge currents. The 16 Ω resistance value and 2.9 A current rating define its operational limits. Consider the thermal time constant and steady-state resistance characteristics to ensure proper circuit performance and adequate heat dissipation under continuous load conditions.

Part Context

This component belongs to the B57236S series of NTC thermistors specifically engineered for inrush current limiting. Manufactured by TDK (formerly EPCOS), these leaded disk thermistors are standard passive elements used to protect sensitive downstream electronics from damaging current spikes during system initialization.
