B57236S0800M000

Overview

The B57236S0800M000 is a leaded NTC thermistor disk designed for inrush current limiting. It features an 80-ohm resistance at 25°C with a ±20% tolerance and supports up to 1.6A steady-state current. Rated for 265 VRMS, it operates between -55°C and +170°C. The component utilizes tinned copper wire leads and a coated body.

Feature Summary

• Provides effective protection against high initial surge currents during equipment startup
• Utilizes a coated thermistor disk construction for environmental durability
• Supports series connections within specified voltage limits

Applications

• Protection of electronic equipment from power supply surge currents
• Inrush current limitation in AC mains input circuits
• Series connection applications requiring voltage ratings up to 265 VRMS

Procurement Notes

Verify the specific resistance value and steady-state current rating against the target circuit requirements. Confirm that the operating temperature range aligns with the application environment. Ensure the through-hole mounting style fits the PCB layout constraints.

Selection Notes

Select this component when a low-resistance path is needed initially, transitioning to higher resistance as current flows. Consider the maximum allowable inrush current and the thermal recovery time required for repeated switching cycles. Ensure the rated voltage exceeds the peak line voltage.

Part Context

This part belongs to the B57236S series of NTC inrush current limiters manufactured by EPCOS (TDK). These components are widely used in consumer electronics and industrial power supplies to protect sensitive downstream components from damage caused by high charging currents.

Replacement Considerations

Compatible substitutes include other B57236S series variants with matching resistance and current ratings. Verify that any replacement maintains the same package dimensions and lead configuration for direct board compatibility.
