Procurement Notes

Verify that the specific order matches the exact model number B57213P0330M301 to ensure correct resistance and current ratings. Confirm that the required safety certifications such as UL, VDE, or CQC are explicitly listed on the official datasheet or product documentation provided by the manufacturer or authorized distributor before finalizing procurement.

Selection Notes

Select this component when an inrush current limiter with a nominal resistance of 33 Ohms and a steady-state current rating of 3A is required. Ensure the physical dimensions, specifically the 14.5mm diameter and 7.50mm lead spacing, fit the target PCB layout. Verify that the application environment does not exceed the thermal limits specified in the official technical documentation.

Part Context

This component belongs to the B57213 series of inrush current limiters manufactured by EPCOS, which is a subsidiary of TDK Electronics. The P13 series designates leaded and coated disk thermistors intended for circuit protection. These components are widely used across automotive, industrial, and consumer electronics sectors to manage initial surge currents.

Replacement Considerations

Cross-reference with other EPCOS/TKD models in the B57213 series if identical specifications are needed. Ensure any substitute maintains the same 33 Ohm resistance, 3A current rating, and physical footprint to guarantee compatibility with existing designs.
