• Provides effective suppression of high inrush currents during power-up sequences
• Features a robust coated disk design suitable for harsh industrial environments
• Offers reliable thermal protection against overcurrent conditions

Applications

• Switching power supplies
• Industrial motor drives
• Power factor correction circuits

Procurement Notes

Verify the specific ordering code against official TDK documentation to ensure correct tolerance and Beta value specifications. Confirm that the physical dimensions and lead spacing match the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component based on the required steady-state current rating and initial resistance value. Ensure the application environment stays within the specified operating temperature limits. Verify compatibility with the system's peak inrush current profile to prevent component failure.

Part Context

This part belongs to the B57234 series of inrush current limiters manufactured by EPCOS, now part of the TDK Group. These components are designed specifically for protecting electronic circuits from damaging surge currents during initial power connection.

Replacement Considerations

Consult official TDK cross-reference lists for verified substitutes. Do not assume generic NTC thermistors are compatible due to differences in Beta values and current handling capabilities.
