B57213P0160M301

Overview

The B57213P0160M301 is a leaded inrush current limiter (ICL) from the S236 series, manufactured by EPCOS (TDK Electronics). It features a nominal resistance of 16 Ohms with a tolerance of ±20%. The component is rated for a maximum continuous current of 4 Amperes and has a disk diameter of 14.50mm (0.571 inches). Designed for thermal protection applications, it utilizes negative temperature coefficient characteristics to limit surge currents during power-up phases.

Feature Summary

• Provides effective suppression of high inrush currents during initial power application
• Utilizes thermistor technology to transition from high resistance to low resistance state
• Supports reliable operation within specified thermal limits for circuit protection

Applications

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

Procurement Notes

Verify the specific ordering suffix and manufacturer branding, as TDK Electronics has discontinued the EPCOS brand name for passive components. Confirm that the requested part number aligns with current production lines or valid legacy stock. Ensure compatibility with required thermal ratings and mounting configurations before finalizing procurement orders.

Selection Notes

Select this component based on the required steady-state resistance and maximum continuous current rating. Evaluate the energy absorption capability relative to the system's surge profile. Consider the physical dimensions and lead spacing for PCB layout constraints. Ensure the operating temperature range meets the environmental requirements of the target application.
