Procurement Notes

Verify the specific part number against official TDK Electronics documentation to ensure accuracy. Confirm that the required resistance value, current rating, and physical dimensions align with the design specifications. Check for updated branding as EPCOS passive components may now carry the TDK brand name. Ensure the component meets the necessary safety certifications for the target market.

Selection Notes

Select this component when a through-hole NTC thermistor is required for inrush current suppression. Consider the 16 Ohm initial resistance and 4A steady-state current limit relative to the circuit's peak load. Evaluate the 14.5mm diameter and 7.50mm lead spacing for PCB layout constraints. Verify that the operating temperature range and thermal characteristics suit the application environment.

Part Context

This component belongs to the B57213 series of inrush current limiting thermistors manufactured by EPCOS, now part of the TDK Group. The P13 series specifically denotes leaded and coated disk variants designed for reliable performance in various electronic applications. These components are engineered to protect sensitive electronics from high initial charging currents.

Replacement Considerations

Consult official TDK Electronics substitution guides for verified alternatives. Cross-reference parameters such as resistance at 25°C, steady-state current capacity, and physical dimensions. Ensure any substitute maintains equivalent safety certifications and thermal performance characteristics.
