PTC Resettable Fuses

PPTCresettable fuse30 VDC0.30 A hold1206 SMDRoHS

JK-nSMD030-30 is a 30 VDC surface-mount PPTC resettable fuse rated for 0.30 A hold current and 0.70 A trip current at 25°C.

Best for

  • Low-current 30 VDC circuit protection
  • Surface-mount designs requiring resettable overcurrent protection

Avoid if

  • Repeated fault conditions are expected
  • Prolonged tripped operation is anticipated
  • Circuit inductance can generate voltage above the device rating

Check before use

  • Confirm hold-current margin at the actual ambient temperature
  • Confirm fault current and trip-time requirements
  • Use the recommended reflow profile and pad layout
