B57213P0100M351

Overview

The B57213P0100M351 is a leaded and coated inrush current limiting thermistor from the P13 series, manufactured by EPCOS (TDK). It features a nominal resistance of 10 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 4A and exhibits a resistance of 197 mOhms under specific current conditions. It has a disk diameter of 14.5mm (0.571 inches) and a lead spacing of 7.50mm (0.295 inches). Certified by CQC, UL, and VDE, this NTC thermistor is designed for robust circuit protection against high initial currents.

Feature Summary

• Provides effective inrush current limitation to protect sensitive electronic components during power-up phases.
• Features a leaded and coated disk construction suitable for through-hole mounting applications.
• Complies with international safety standards including UL, VDE, and CQC certifications.

Applications

• Power supply input stages
• Switching mode power supplies
• Consumer electronics circuits

Procurement Notes

Verify the exact part number suffix to ensure correct resistance value and tolerance specifications. Confirm that the required steady-state current rating of 4A aligns with the application's operational limits. Check for updated branding as TDK may have transitioned product labeling from EPCOS to TDK Electronics. Ensure compliance with RoHS directives if required by the target market regulations.

Selection Notes

Select this component based on the required 10 Ohm nominal resistance and 14.5mm diameter constraints. Evaluate the thermal characteristics to ensure the device can handle the expected energy dissipation without degradation. Consider the lead spacing of 7.50mm for PCB layout compatibility. Verify that the ±20% tolerance meets the circuit design requirements for inrush current control precision.

Part Context

This component belongs to the B57213 series of inrush current limiters, which are negative temperature coefficient (NTC) thermistors. These devices are widely used in various electronic equipment to suppress surge currents. The P13 series designation indicates a specific form factor and coating type optimized for general-purpose industrial and consumer applications.

Replacement Considerations

Check for direct substitutes within the B57213 series with matching resistance values. Verify equivalent thermal and electrical ratings when considering alternative manufacturers. Note that TDK may use updated part numbering or branding conventions following the integration of EPCOS products into the TDK portfolio.
