B57213P0800M351

Overview

The B57213P0800M351 is an NTC inrush current limiter from the P13 series, manufactured by TDK EPCOS. It features a nominal resistance of 80 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 2A and exhibits a low-temperature resistance of 197 mOhms. Its physical dimensions include a diameter of 14.5mm (0.571 inches) and a lead spacing of 7.50mm (0.295 inches). The device carries CQC, UL, and VDE certifications for safety compliance.

Feature Summary

• Leaded and coated disk design for robust inrush current limiting
• High steady-state current handling capability
• Low cold resistance to minimize power loss during operation

Applications

• Power supply input protection
• Consumer electronics circuit protection
• Industrial equipment surge suppression

Procurement Notes

Verify that the specific part number B57213P0800M351 matches the required 80 Ohm resistance and 2A current rating for your application. Confirm that the package type and lead spacing align with your PCB layout requirements. Ensure that the manufacturer source is authorized to guarantee component authenticity and traceability according to TDK EPCOS standards.

Selection Notes

Select this component when an 80 Ohm initial resistance is necessary to limit peak inrush currents in circuits requiring up to 2A steady-state operation. Consider the 14.5mm diameter for available board space and the 7.50mm lead pitch for mounting compatibility. Evaluate thermal management needs based on the specific energy absorption requirements of the target application.

Part Context

This component belongs to the B57213P series of NTC thermistors designed specifically for inrush current limitation. These devices are characterized by their ceramic composition and coated disk structure, providing reliable performance in protecting sensitive electronic components from high startup currents common in AC/DC power supplies and other electrical loads.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. Verify cross-reference availability through official TDK EPCOS channels or authorized distributors to ensure equivalent electrical and mechanical specifications.
