B57211P0160M351

Overview

The B57211P0160M351 is a leaded and coated inrush current limiter (ICL) from the P13 series. It features a resistance of 16 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 3A and has a diameter of 13mm (0.51 inches). It includes a nickel barrier termination for surface mounting compatibility.

Feature Summary

• Leaded and coated disk construction designed for robust inrush current limiting applications
• Nickel barrier termination structure ensuring superior resistance stability during soldering processes
• High accuracy resistance rating suitable for precise thermal management requirements

Applications

• AC mains front ends within thermal operating range
• Mobile phone battery packs
• Data systems power inputs
• Automotive electronics circuits

Procurement Notes

Verify the specific part number against official TDK Electronics documentation to confirm the 3A steady-state current rating and 13mm diameter dimensions. Ensure the nickel barrier termination matches the required soldering profile. Cross-reference the P13 series datasheet for accurate thermal derating curves and certification details such as UL or VDE compliance before finalizing procurement specifications.

Selection Notes

Select this component when the application requires a leaded inrush current limiter with a 16 Ohm nominal resistance. It is appropriate for AC mains interfaces where the steady-state current remains below 3A. Consider the 13mm form factor for board space constraints. Verify that the inrush profile aligns with the device's thermal capabilities and that the nickel barrier termination is compatible with the assembly process.

Part Context

This component belongs to the B57211 series of SMD NTC thermistors with nickel barrier termination, manufactured by EPCOS (TDK). While often categorized under temperature measurement, this specific variant functions as an inrush current limiter. The P13 series designation indicates its physical size and coating type, distinguishing it from other leaded or uncoated variants within the broader TDK passive component portfolio.
