B57213P0600M301

Overview

The B57213P0600M301 is a leaded inrush current limiter (ICL) from the EPCOS P13 series. It features a 14.5mm disk diameter with a nominal resistance of 0.695 Ohms at 25°C and a tolerance of ±20%. The component supports a maximum steady-state current of 2A. Key electrical parameters include a residual resistance of 197 mOhms at specific current levels. Physical dimensions include a 7.50mm lead spacing and a minimum lead length of 25.00mm. It operates within a temperature range of -40°C to +170°C.

Feature Summary

• Provides effective limitation of high inrush currents during power-up sequences
• Offers stable thermal performance across a wide operating temperature range
• Features robust construction suitable for through-hole mounting applications

Applications

• Power supply input stages for consumer electronics
• Industrial equipment power interfaces
• Automotive electronic control unit protection

Procurement Notes

Verify the specific ordering suffix against official TDK documentation to confirm exact resistance values and package variants. Ensure compatibility with target PCB footprint dimensions, specifically the 7.50mm lead spacing. Confirm that the 2A steady-state current rating meets the circuit requirements without exceeding thermal limits.

Selection Notes

Select this component based on the required nominal resistance of 0.695 Ohms and the 2A current handling capability. Consider the 14.5mm body size for spatial constraints. Evaluate the -40°C to +170°C operating range against environmental conditions. Compare residual resistance specifications to minimize power loss during normal operation.

Part Context

This part belongs to the B57213P series of NTC inrush current limiters manufactured by EPCOS, now integrated into TDK Electronics. These components are designed to protect sensitive electronic circuits from damage caused by high initial charging currents when connected to a power source.
