JK-SMD0603-003-30V

PTC Resettable Fuses

PPTCresettable fuse30 VDC0.03 A holdSMD0603

A 30 V SMD PPTC resettable fuse rated for 0.03 A hold current and 0.09 A trip current at 25°C.

Best for

  • Occasional low-current overcurrent protection
  • 30 VDC electronic circuits
  • Space-constrained SMD assemblies

Avoid if

  • The circuit cannot tolerate high series resistance
  • Repeated fault cycling is expected
  • Circuit voltage can exceed 30 VDC during inductive transients

Check before use

  • Hold-current derating across -40°C to 85°C
  • Trip behavior at the actual fault current
  • PCB footprint and reflow profile
  • Inductive transient voltage
