Inrush Current Limiters (ICL) Procurement Notes

Verify the obsolete lifecycle status before finalizing design specifications. Confirm that alternative components are available if long-term supply continuity is required. Ensure compatibility with existing PCB footprints and thermal management requirements. Check for any updated datasheets or replacement recommendations from Murata Electronics to mitigate supply chain risks associated with discontinued parts.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on its specific 3.0-ohm resistance value and high thermal capacity indicated by the 130-second time constant. Consider the ±15% tolerance for circuit design margins. Evaluate the radial package dimensions against available board space. Assess the maximum operating temperature limit of 160°C relative to the ambient environment. Compare the dissipation factor against heat dissipation capabilities in the target application enclosure.

Inrush Current Limiters (ICL) Part Context

This part belongs to the NTP series of NTC thermistors from Murata Electronics, specialized for surge current protection. These components are distinct from temperature sensing variants like the NCP series due to their higher power handling and lower resistance values. The NTP series is engineered for durability in high-energy switching environments common in consumer electronics power stages.
