Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix M000 against official TDK documentation to confirm tolerance and packaging details. Ensure the application voltage does not exceed the rated limit. Confirm that the thermal environment remains within the specified operating range to maintain performance integrity.

Inrush Current Limiters (ICL) Selection Notes

Select this component when significant inrush current control is required for AC or DC input stages. Evaluate the steady-state current requirements to ensure the thermistor does not overheat during normal operation. Consider the physical dimensions and lead spacing for PCB layout compatibility.

Inrush Current Limiters (ICL) Part Context

This part belongs to the B57364 series of NTC thermistors manufactured by EPCOS, now integrated into TDK Electronics. These components are widely used in consumer electronics and industrial equipment for circuit protection. The brand transition from EPCOS to TDK has standardized product naming and distribution channels globally.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other 30 Ohm, 18W NTC thermistors from manufacturers such as Murata (NTCLE100E) or Vishay (PTC05). Verify electrical parameters and mechanical footprint before substitution.
